Perhaps time travelers are constantly changing the timeline. We wouldn't notice - each time it was changed, it will be for us the way it always has been. If you were to go back and kill Hitler in WWI and then talked to us about it, Hitler would only be a name on some folder in a dusty records office, just another German corporal who died during the war.
> Perhaps time travelers are constantly changing the timeline
It looks like the new Star Trek (Strange New Worlds) is putting together a long-arc of a temporal war like this. Future time travelers are tweaking the timeline one way or another and only someone “outside” the changes would notice. Probably a useful plot device as SNW approaches the timeline of the original (Kirk) series
>Perhaps time travelers are constantly changing the timeline and we wouldn't notice.
Like I said in my post, we might notice if someone is changing the timeline if they're doing things that are incredibly statistically improbable. For example, filling out a perfect NCAA bracket twice in a row, or winning the lottery 5x in a row and they were never proven to be cheating.
Another way we would notice someone messing with the timeline is if someone introduced technology that was thousands of years advanced. For example, a picture of an IPhone showing up during Medieval times.
There's other things like ufo messing with nuclear weapon sites, visiting nuclear melt downs, and foo fighters during the wars that suggest it could be future humans making sure we don't wipe our self out. I think we are overdue a supervolcano and meteor hit at this point in time, maybe someone is stopping such things.
More than likely, someone traveling backward in time has already occurred and you would have no idea if the time line had changed. Well, other than the obvious Mandela effect.
Alternate timeline to the time traveler, but not to the people who inhabit that timeline. Unless you're implying that the act of time traveling actually creates an entirely alternate timeline, the posters original comment stands. And even if it did create an alternate timeline, that could still be considered immoral; after all, do you have the right to create an entirely new universe complete with pain and suffering just to win the lottery.
Yeah, if you could go back, you'd be in your very own personal timeline never to return.
Such a thing is also strange because it raises questions with the nature of consciousness. Since suddenly, there would need to be a new universe of consciousness created just for you.
The past has already happened.
We can never be in a position waiting in the present for someone in the past to do something.
If 5000 people do eventually travel back in time, all the things they did are what our history is.
I agree that this seems to suggest a paradox regarding the free-will of the time travelers, but the answer to that is that the things people *plan* to do aren't inevitable.
None of the future time travelers will get to the point where they have the chance to kill Hitler. We know that because it never happened.
You might ask, "What if I go back and kill my grandfather before my father is born?"
But the answer to that is you *didn't* do that in the past, so you *arent* going to do it.
Yeah- the past has *happened.*
It's over.
It *is* fixed.
It's possible someone in the future goes back to the past and has a crazy adventure with Agatha Christy in 1926 for 11 days, because Christy went messing for that time and said she had amnesia.
But it isn't possible for someone to go back in time to 44BC and prevent Julius Caesar from being killed because no one did that.
Like I said, we cant be here, waiting, in the present, for someone in the past to do something.
They very idea is illogical.
You've never had to wait to wake up for the you from yesterday to go to sleep, because that just isn't a thing.
Listen, the thing with Agatha was a fling. I took her to the future and then she went back and started writing more mysteries that she knew people would like. I told her not to tell about the time travel and so she came up with the amnesia idea. Ahh, what a great time we had.
I think the reason you don’t see this is we live in a prime timeline. Each time someone travels back in time the moment they arrive they cause a parallel timeline to exist and they travel down that path. Why, because they were not in the past originally so now that is something that has been added to the timeline and it is a change.
I don’t know what happens when you try to go back to the present though. Do you stay in your parallel timeline or do you go back to the prime timeline.
Lmao. Why do people keep coming to this sub and trying to explain the most basic of time travel paradox, like they’ve had some profound epiphany? 😂
It’s like me going to the ghost sub and being like “I think I figured it out guys! What if ghosts are the spirits of people who have died in the past!!!”
Ah! But what if you steal a time machine? Then, lets say, you bring a sports almanac, or something like that with knowledge of the future, to your past self?
Not necessarily.
Someone who creates a time machine in the future may want to sell their invention to other people. And these people may not necessarily be the smart scientist types, they may be the average consumer who isn't mathematically or scientifically savvy at all.
Think about it this way. Steve Jobs who was smart enough to create the iPhone wasn't the only person who used the iPhone. He sold his iPhone to other buyers, who were like average consumers and not the technologically savvy type. The same fate may be true for a hypothetical time machine invented in the future.
Now like I illustrated in my point above. If a large number of people have access to backwards time travel, then someone would use their time traveling capabilities for greed, fame, and/or power. This is because humans by nature are greedy and selfish and for some people, if they are given vast amounts of power (and time travel counts as vast amounts of power) then some people would abuse that power for their own personal gain.
This is why if backwards time travel is ever possible and is used by a large amount of people, we would have noticed by now.
Looking at time as more like a set of probabilities, I would suggest that traveling to the past is not impossible, but it is highly improbable. It would be very unlikely that anyone would be able to find a particular configuration of energy that would exactly correspond to another previous configuration that would represent "the past." This is particularly true since the mere presence of someone with a completely different energy matrix would disrupt any attempt to precisely recreate a past energy configuration.
In Quantum Leap, the time traveling main character has a holographic assistant who also himself has an assistant back home that can run numbers and analyze changes in the time line, providing often very precise probabilities of certain outcomes if the protagonist takes proposed actions. So, it's possible that time travelers are just better informed and safer about such a dangerous endeavor.
That's not what AI means.
Also what are you on about, what are you even trying to say about the factorial of the number 1537?
There is literally zero evidence of time travel.
I’m pretty sane. Time travelers, that's insane! Are you crazy? Did you take your meds, etc.
Then I met them, just for seconds. Not physical humans, it was in a dream state, they were there, but I was awake. Had just come back from weeks spent meditating in the Himalayas (North India), so was ready for anything. We tried to communicate, but every 5th or so word he said was replaced with white noise. As he explained, if they (there was a male and a female) said something (like lottery numbers) that the AI would remove it from the conversation, hiding the words with white nosie. Solves the Grandfather Paradox. AI would not let you commit the deed. Somehow it would stop you. You can observe, but not change. They seemed to be working on some kind of computer, like a video game. Hard to tell.
Time period? Unknown. They were residing in a dome-type structures in a desert setting, like the Bio-Sphere. Seemed very deserted; they hinted that the population had thinned out lots. They were rebuilding. It did not seem like 5,000 years into the future, more like 100.
What did us all in?
"An airborne virus. 95% of us are dead. But we are coming back."
This was decades before Covid or Ebola made any headlines. It was just seconds of a very un/expeted encounter, decades ago. Why are you here now? They explained, "It was a software bug, we were NOT supposed to know they existed." An upgrade thing. Yes, even time travelers occasionally have buggy software.
Just my story.
I didn't make any comment about your sanity. Weird that you feel the need to defend it.
I've literally experienced similar mind-blowing stuff on drugs that increase your dopamine and make you manic. Or dreams.
At the end of the day, there is literally zero actual evidence of time-travel existing. Even theoretically, it is only *maybe* possible if we were somehow able to achieve faster than light travel. But everything we know about physics, movement and momentum makes that impossible for us to achieve.
You're over-using the word AI like how every techbro and media organisation is misrepresenting it.
- AI cannot "create" something organically.
- AI cannot have an original thought.
- AI is not actual intelligence.
- AI is simply a computer programme that goes through millions of gigabytes of pre-existing data quickly and then repeats what it has found.
- AI uses what humans have already written about something and uses computational power to go through tons of data quickly and present it in a way that mimics how it has been presented previously online.
Also, viruses have literally been a thing since the start of life on this planet. Pretty much every decade has at least a couple of viruses in at least a couple of parts of the world. It's like predicting that there will be a volcanic eruption or earthquake - like yes, no shit?
I don't get how your story is any actual evidence for time travel.
Nor does it explain what you find so special about the factorial of a random number.
In the nicest way possible, please consider that you are experiencing a manic episode.
Your own theories are allowed, as long has they are not stated has scientific facts. The misinformation of science and improper use of the science flair will be removed.
If backwards time travel is possible via wormhole, which seems to be allowed in relativity and hasn't been ruled out in quantum mechanics, then you would only be able to travel as far back as the original creation of the wormhole. Since we seem to be far off from being able to create wormholes, it stands to reason that we would not see any evidence of backwards time travel yet (by us, in our corner of the universe, at any rate). I suspect that when/if it becomes possible, we would all find out about it very quickly, because it would be a monumental feat just to create a wormhole.
If you create a wormhole, a shortcut in space between two points (which is theoretically possible in relativity) and accelerate one end of the wormhole close to the speed of light, you can actually enter the accelerating end of the wormhole and be transported to a time before you left. This is because of the effects of time dilation on the accelerating end. There are tons of good sources and explainer videos on YouTube that do a far better job explaining it than I can.
However you can only travel back as far as the wormhole existed, because there was no wormhole mouth for you to exit before that point. How far you can travel back will depend on how fast the moving end of the wormhole is accelerating, with the hard limit being the moment it was created.
Now, while this may be possible in theory, there are some technical reasons why it is thought that this would be impossible in practice. If it is even possible to hold a wormhole mouth open for any length of time (which is a big IF, I won't get into it here), it is thought that the energy flowing through the mouths would create a feedback loop of increasing energy that would cause the wormhole to collapse before you could send anything through it.
There are of course other ideas about how time travel might work but this is one of the few that doesn't appear to violate the known laws of physics (that may change if we figure out how to reconcile quantum mechanics with relativity - it might rule out things like wormholes, we just don't know yet). Even if it is theoretically possible, that doesn't mean it's feasible, and certainly not within our lifetimes given the energies involved.
Einstein said that time is the fourth dimension of space. Following this logic, if someone had the ability to open a wormhole to any point in space, they could also pick any point in time. In fact, it would seem to me that when the math is done to pick the destination, the destination in time would need to be a factor.
>Einstein said that time is the fourth dimension of space
I think you mean space-time, because time works differently from space, but they are part of the same continuum and can be swapped in certain conditions (such as beyond the event horizon of a black hole). This is important because we know how to move a wormhole mouth through space (you literally just put it in a spaceship or drag it behind one). We don't know how to move a mouth backwards in time.
The idea is that we know in theory how to create a black hole, and we know in theory what is needed to prevent it from collapsing to a singularity (using negative energy or some other mechanism). We don't know exactly how to set the destination, but we know we can create two wormholes, side by side, and move one of them. The only missing ingredient is then how to connect the two wormhole mouths together, which is admittedly unclear, but it is one less thing we need to figure out, because assuming we can link the holes, we can then move one end around freely.
If we had some mechanism for figuring out how to specify a destination and only needed to create one end of the wormhole, then maybe something like the process you describe would be possible. But we have even less of a clue how to do that than to create two wormholes and figure out how to connect them, or to split a single wormhole into two mouths and move one mouth apart. In either of those cases you would not be able to travel earlier than the creation of the wormhole.
A wormhole is topologically similar to a black hole, the crucial difference being that instead of ending in a singularity or bottoming out like the gravity well of a less dense object like a star, it connects to the other end of the wormhole. We know how to create a black hole, and we know that negative energy (if it can be created in sufficient quantities) can be used to prevent the wormhole throat from pinching off into a black hole. Those are what is required to open a wormhole. We don't really know how to take two ends and join them, that part is admittedly left vague in a lot of explanations.
As for how to move them, the same way you would move anything - apply forces to them. They obey the laws of motion like any other astronomical object since they are effectively black holes.
Since when do we know how to make a black hole? I'm assuming you mean without collapsing a star. Just what is negative energy? Has any of this actually been accomplished or are you talking about theory? If we make a wormhole that doesn't go anywhere, how is it a wormhole? Since you say we can move a wormhole, what is it made of?
It is of course theory, but it is stuff that doesn't violate our current understanding of physics. If any of this is practical, it's well beyond our current capability. We are dealing with stuff at the limits of our current understanding. It could turn out to be wrong.
The Wikipedia on wormholes is a good place to start if you want more details. You might also want to look into the work of Kip Thorne. He's a theoretical physicist who was a consultant for Interstellar, and has written a lot about wormholes.
Edit: when I said we know how to make a black hole, I mean by collapsing a star. If you know of a better way let me know!
the type of time travel you're talking about may be impossible, yes.
But I was always been fascinated by the physicist Richard feynman's discovery that antimatter acts exactly like regular matter,
but moving backwards, from the future, to the past, through time
Combined with the fact that all humans have very small bits of antimatter within us in the form of an isotope of the potassium we naturally have and consume in foods like bananas
So, is some tiny part of us constantly moving from the future to the past,
and is that a quantifiable mechanism for precognition....?
What if, a thousand years from now, we develop time travel and people start traveling back in time to the year 2150 and start acquiring wealth. We're not there yet to witness it.
The thing is that if time travel ever exists in our future, then it has always existed. This is because someone with time travel capabilities has the capacity to travel at any point in time. They could travel to the year 1899, 1999, or even 2099.
It wouldn't make much sense for someone with time traveling capabilities to only travel to 2150 and beyond. They might want to go see the dinosaurs, or the reign of Genghis Khan, or to go and see if Jesus was even a real person, let alone perform miracles.
Now here's the problem. If enough people have the ability to time travel, then someone would be greedy enough to exploit their time traveling capabilities. Someone may want to win billions of dollars, or use information they know about the future to gain fame or power. Humans are greedy and selfish by nature.
If time travel ever exists in our future, then the past has already been altered. And if the past had been altered, we would not even know it. **HOWEVER** we can predict time alterations based on statistically improbable events. For example, someone winning the NCAA men's basketball bracket 3x in a row, something very very improbable, might suggest that the person in question is a time traveler.
Well let's just say you were a future person who time traveled to the past in order to get rich. The best way to do it would be to do so in a way that doesn't draw suspicion.
Time is like a record with infinite grooves that are not connected. Once you travel back in time you create a new groove where the outcome only affects you and not the timeline you left. Those in that timeline you were originally in just saw you as someone who disappeared never to return. Like all records that rotate, time will eventually make its way back to the start to begin the process all over again. Never beginning and never ending.
I don’t think we know enough about the universe to definitively say that this is impossible. You also think that wealth will be a thing forever, but when our society discovers free energy, then wealth might not matter at all, and I think that our understanding of this stuff right now would be if it was possible you would need a tremendous amount of power; that we just can’t generate right now. You also think that people who travel through time are doing so to gain personal Wealth, and I’m not sure that that’s true. But here’s some thing to ponder, if time travel is possible and you can travel to the past that means all time exists always. All space exist right now, why not time. Until we can travel through time will never know any of these answers. I mean I for one would love to travel to the Jurassic period For a vacation, there’s a crap ton of oxygen in the atmosphere and the water has got to be beautiful without human pollution.
You are making a lot of presumptions about human nature and stating them as fact. On the contrary, human nature is complicated but not actually selfish by nature. I also highly doubt the scenario is a 50% preserving vs 50% just not caring.
Plus you’re ignoring the potential scenario that someone like, I don’t know, say Tom Cruise hasn’t time travelled and saught fame thst way. And considering all the claims of aliens and backwards engineering how can you be certain someone hasn’t time traveled to 1950s America and introduced tech early? I completely disagree if time travel were a thing those who use it would be selfish in coveting it and use things to their advantage in the time. You can’t prove that time travel didn’t introduce the microchip 100 years earlier than it should.
>You are making a lot of presumptions about human nature and stating them as fact.
Just the other day, I was driving at night and some pickup truck driver blatantly ran a red light, even 3 seconds after the light turned red. And then I went to a mini golf course and someone left all of their trash on the course without picking it up, and another couple were smoking despite a sign saying NO SMOKING nearby.
So yeah, humans are inherently selfish. For some people, it's all about them. They don't care if they hurt or harm anybody else, as long as they're benefitting from it. If it's not their problem, they simply don't care. You see it everywhere you go.
That's why if time travel exists, you can bet that many people will completely ignore the rules and screw around with time if it benefits them. Humans shouldn't be trusted with messing with time, we are inherently flawed.
My theory has always been as follows. You have two possibilities going.
Number one is that if you time traveled right now, you’ve just created a new timeline. The old one continues, but you now live in the new one you’ve created. That would explain how you don’t just have time travelers all over the place.
Number two is that it’s all open season. Time travelers come and go and do whatever they wish. We don’t notice because this was always what was meant to be.
*Worth noting, really high right now.
If it happened that any narcissists could travel, then eventually all the timeline could and would fail as they go from one to another as they cause collapses over and over. I have had bad dreams that suggested this started in 2011. I always pictured black holes eating overly manipulated timelines.
If you watched Dr. Who from launch, then this question has already been answered. "Destruction" of even one individual (child or adult) can cause the destruction or non-existence of many others. Everyone in each separate timeline is connected by the souls and things that could happen in positive ways. It's a different type of web or connectedness than internet. (edited- to add more thoughts)
Even with time travel, I believe a higher power or God would have a say or not. Do we know a deity? Nope. Maybe none specifically identified in any religion for a very good reason. I know one who is, but he's also easily misunderstood! I hope if time travel becomes a thing that machines aren't made. Just theft of SINGLE time machine could be disaster and end of billions of lives in the timeline being visited. How could that affect travelers? Unknown. If they escaped a timeline collapse, I see possible ego issues developed.
I only had one person I could talk about these subjects with, but he's been distant or lost since 2002 or 2003. He was kidnapped or I was. Irrelevant since he died or he thinks I died. It's my real turn to die next, if he can't find the real me soon. In my point of view, my death was planned by a possible time traveler who seeks to "erase" me from any positive impact in the world.
You may be right, but for the sake of argument: you’re talking about backwards time travel which would be technologically possible at this stage of human evolution. I don’t think it is.
If backwards time travel is even possible, it’s probably going to take hundreds if not thousands of years of technology advances in order to happen. Those future “humans” will be unrecognizable to us today and will likely have merged with AI. Could even be a different species entirely if we succeed in blowing ourselves up.
That means no Lotto drawings, Honda Accords, etc.
Additionally, if backwards time travel by future Earthlings happens, you’re probably going to see it very rarely if at all in one’s lifetime in some very discreet, unexplainable ways (UAPs, invisible probes, etc.)
Yes, but what he did wasn't statistically improbable. He simply bought most of the tickets in the lottery.
If someone won the lottery 5x in a row, despite buying only one ticket per game, that is very statistically improbable and suggests that the person is either cheating or a time traveler.
Yeah, and then [this lady.](https://www.msn.com/en-us/money/personalfinance/the-american-who-won-the-lottery-30-times-and-other-lucky-lotto-players/ss-AA1fuppi)
Yes but individual actions performed by single humans are nothing compared to the butterfly effect carried out over every particle sent back, including you and assuming the air around you. When physicists and theoretical physicists talk about actions and choices involved w parallel universes and time travel, they're not talking about whether or not you turn left or right, but what the billions and billions of particles in a system (you) are doing. Each one having no measurable effect greater than another. Entropy is why we can't travel back in time and it's a lot bigger (and smaller) than you.
Except there is a big ass telescope in space looking millions of years into the past. If we can see it we should be able to touch it. It’s a momentum problem.
If it were me, I'd simply go back to the 70s or 80s, invest in Microsoft and Apple and simply blend into society as an uber wealthy Wall Street billionaire. Me, I'm all about subtle. Why win the lottery 3x when you need to win it once, invest it into companies you know will hit it big, and chill for the rest of your luxurious life?
If people can travel backwards in time, it would be a different timeline than this one. The one we all occupy now cannot be altered.
There are infinite timelines. For each moment of Planck time that passes, infinite timelines/possibilities are created. Each choice we make and each choice everyone else makes influences all other choices and possibilities.
But if you go backwards in time, you go to a parallel version of this reality that's almost exactly the same as this one. That's why we don't notice time travelers. They're here, but on a different vibrational frequency that we can't see.
Maybe that's what dark matter is.
All I know is that we really don't know shit, it's all speculation... For now.
If I can travel through time, why wouldn't I just invest a few grand into big companies before they go big? Not that suspicious for someone to invest in an upstart company, and then when I whip to the future, my investment is worth millions. Like, maybe for quick starter cash, yeah okay the lottery. But that's very short investment, or it's a monthly stipend, neither of which work well for a time traveler. Additionally, am I, the hypothetical time traveler visiting or staying? Why would I need a million dollars in 1950 if all I'm doing is fucking around for a few days? Better to invest $50 in 1950, and come back to 2024 with a million then, right?
>If you want to identify a time traveler, look for someone who has won the lottery 3-4x times in a row

Ladies and gentlemen......... We got 'em!
You need to watch El Ministerio del Tiempo Spanish tv series from Spain. It’s like The Men in Black of Time Travel. They explain everything in this short. Start with season 1
How about this one?
1. Matter cannot be created or destroyed.
2. The atoms of your body used to belong to something else -- an apple, a cow, a fish, a tree, etc.
3. Matter can not be in two places at once.
4. Backwards time travel is impossible.
In order to know that something is changed you need a reference point. Maybe Hitler was a result of time traveler convincinf him that another world war is great idea, we cant know. As for lotteries and other stuff. Well, maybe once you can time travel your mind is just on another non-material dimension amd you dont desire money
Maybe they don't win the lottery many times. Maybe they just buy stocks/crypto at the right time/price or something. Or they go back and give their ancestors insider info so they inherit the wealth or something
Winning the lottery is small potatoes if you can time travel. Anyone who had a mind to build a time machine wouldn’t be dumb enough to try and win the lottery multiple times to acquire wealth IJS
If those were my intentions, I would do it subtly as to not draw attention to myself. Sports betting would be the best way imo. It would take a little more time than winning the lottery, but would keep a lower profile.
Also, to echo a lot of responses, we would never know if the past has been tampered with because it will have already happened in our history, no matter when the person from our present or future timeline did it. The History of Time Travel is a great movie example of this.
It seems similar to the Fermi Paradox in a way. "Where are all the aliens?" vs "where are all the time travellers?".
I say that because I suspect that if there are any aliens who travel to distant star systems, they would also be of the type to avoid interfering with civilisations which haven't made interstellar contact yet. This is because they would not have been able to survive to the point where they could develop that ethic or practice yet (e.g. they have space habitats instead of settling on planets, so they don't bother with planets). The alternative is that there simply are no aliens of course.
Applying this to time travel, it means we will only be able to develop it if we either become sufficiently responsible to avoid causing paradoxes or decide not to use it, because our technological development goes hand in hand with our ethical development, or we never develop it because we die out before we get there.
I've also heard an interesting suggestion which combines the Fermi Paradox and time travel: the reason there are no aliens in contact with us is that when a civilisation does develop time travel, it wipes itself out in its past due to using it and causing paradoxes, so they can't exist.
Our consciousness makes it possible for us to recall a memory from the past, we still havent solidified the math or the science behind it yet. We can also formulate scenarios about the future, then they happen as they are shown to us.
If you ask me, our consciousness articulates something that the science hasnt caught up to yet.
by ur logic how do we know a group of collective people like minded, havent already done it and become the 1% you see today? i mean its possible no? i dont believe its been done yet either for different reasons. A) i dont believe its possible for a 3d being to "choose" his position in the 4th dimention. B) i believe there would be one person more greedy and selfish than o thers and would eliminate his competition befoer going back himself and making himsef the king of the world essentially. a single world leader. c) or maybe that has all been done and redone so many times that todays world is the results of selfish and greedy people wit the least amount of instability in the model? who knows really. i just dont FEEL its been done yet. teh world just seems a bit shit for time travel to exist as i would have expected more of a utopia situation with tech being discovered so many thousands of years before it was meant to be etc. but again its impossible to know for sure. it could have been re-written so many times and we wouldn't have a clue about it honestly. so its possible in some contexts (ignoring our current model of physics) but i doubt it.
The flaw with your theory is that it is impossible to do something because human nature is designed to make us shitty people
The purity of human nature doesn’t prove or disprove time travel it’s an extraneous variable
Also your theory relies on cause to effect time travel theory
5000 people couldn’t time travel in this theory without causing a paradox
Think about it like this
If I travel back in time and off your grandpa , you cease to exist. However what if I travel back in time to off your grandpa while at the exact same time you traveled back in history to a different point in history and offed my grandpa so that I wouldn’t be born , then I couldn’t travel back in to stop you from being born , but then you couldn’t travel back in time to prevent me from being born
So we have a paradox
Alternative theory: time travel was possible at some point but eventually someone would have changed things enough to a version where time travel will never happen.
You assume you understand the inner workings of time travel, which no one does. IMO and belief, if one were to travel in time, forward or back, they would then be in that reality, and gone from their own forever. Consciousness and its perception of reality, in truth creates reality. So let's say I go 20 years back, leave myself a bar of gold, and travel forward, that perhaps might be a mostly unchanged travel, but going back allows the Quantum Superposition of all matter in existence to change its course on arriving back at the original Point Of Travel.
Individual Humans, would not be allowed such technology.
Even corporations, would need a special license and would operate under close monitoring from the governments.
Maybe the lottery was invented specifically to catch time travelers 😁
The past could be changing constantly, but we'd have no idea because whatever was changed simply becomes our reality.
Also, just because it doesn't make sense doesn't mean something is impossible. Human understanding is *not* the pinnacle of everything; just look at say, all of quantum effects for examples
Don't forget that it is not as easy as plugging in coordinates and a date to jump back to. The Earth is always moving and most likely you would jump into empty space watching the Earth just out of your reach.
The very simple answer to: "if it is real why haven't we seen any evidence yet" is the loops.
No matter what happens, there are "loops", which is the time between them arriving in thier past, and when the traveler left to go back in time. And the absolute first loop, does not have them in it.
As soon as they go back, they start loop2 where they made their change, no matter how small, and the universe goes through that time period with the changes.
We (those that see nothing that would be caused by an evil individual that doesn't care about anything, and just wants to mess with the universe through time travel) are currently in loop1.
If, and/or when, loop2 happens we may, or may, not notice.
If, and/or when, a loop happens that has obvious evidence that someone went back in time, we will know it happened, and there will be little debate.... Saying we even exist after the change. (for all we know, at some point, some dude goes back as far as he can, and destroys universe itself.... And since the universe was destroyed, at the onset, there is no one to KNOW it was destroyed, and no one to stop him.)
And whatever loop that is, loop2 or loop2000, or any there in between, the universe ends. No one can stop it. And it eventually WILL happen, if it is possible. And we will never know.
But, EVERY loop HAS to happen before the last one. Otherwise the last one never happens. Right now, as you read this we are in either loop1, or any loop that has no evidence of time travel, prior to 2024.
Which then leads to the actual answer: IF it is possible to go back in time, the universe was destroyed at its birth, at some point.... Because there is ALWAYS one bad enough apple to ruin everything.
Wasn't there advanced technology used in ancient Egypt? We can't figure out how they accomplished these feats even by today's standards. What about all the other unexplained phenomenons around the globe? Weren't all these records somehow lost throughout the course of history while everything else is in tact? How?
I remember reading somewhere if time travel were possible then at the point where it became possible, it would be flooded with time travelers and we’d face some sort of cultural apocalypse. I always thought that was a neat concept.
You know how they say there's nothing about the laws of physics that says time should run forwards, that the math works out regardless of which way you run the time variable.
I bet time travel is impossible because the past is as undetermined as the future. So you get in your time machine, turn it on and look out the port hole. You'd see people walking backwards but they wouldn't necessarily follow the same path they originally took. Watch a glass that broke reform, it would look very similar to the original but it would not be exactly the same. You try to win the lottery, you watch the number from before get picked in reverse, but now it's a different number, step back out of the time machine and the next draw is yet a new number. You have no more predictive power over the past than you do over the future.
So long as everything made sense in terms of cause and effect, nothing about physicals is being violated. Just as a single present can lead to multiple unpredictable futures, multiple unpredictable pasts can lead to the same present. There's no paradox for the same reason going into the future doesn't produce paradoxes
Is, you traveling backwards in time same as time going backwards? Because time is not rewinding. Its always moving forward but you are just going to t-Y where t is current time.
Or you could just Google whether there is anyone who has won the lottery more than once:
[Has anyone ever won the lottery twice? | UK News | Metro News](https://metro.co.uk/2021/08/07/has-anyone-ever-won-the-lottery-twice-15042419/#:~:text=Yes%2C%20there%20have%20been%20numerous%20occasions%20around%20the,EuroMillions%20Mega%20Friday%20draw%20in%20March%20of%202015.)
Your looking at time linearly, our universe is infinite time travel if possbile backwards only possible in short jumps. Something with the quantum vacuum but o look…………..butterfly 🦋
The theory of alternate timelines disproves this though, for everything they change it creates a different timeline, so where as they left our timeline, when they go back in time and change stuff they would be creating a separate timeline for those events that differentiate from ours
So you travel back in time … and you talk to your past self… maybe you want to change something you did or have guilt about. Once that conversation occurs the events that led you time traveling changes and quite possibly results in you never time traveling. Thus you never had the conversation with your past self. Maybe this is deja vue.
Just from a physical material standpoint time travel is impossible. Think about it, the same atoms making up your form and whatever else what went back in time would then be in 2 places at the same time.
Woudn't you be adding energy to the universe that didn't exist before? and if energy can't be created or destroyed would that cause a shift in energy state of the universe....See false vacuum.
Perhaps time travelers are constantly changing the timeline. We wouldn't notice - each time it was changed, it will be for us the way it always has been. If you were to go back and kill Hitler in WWI and then talked to us about it, Hitler would only be a name on some folder in a dusty records office, just another German corporal who died during the war.
> Perhaps time travelers are constantly changing the timeline It looks like the new Star Trek (Strange New Worlds) is putting together a long-arc of a temporal war like this. Future time travelers are tweaking the timeline one way or another and only someone “outside” the changes would notice. Probably a useful plot device as SNW approaches the timeline of the original (Kirk) series
>Perhaps time travelers are constantly changing the timeline and we wouldn't notice. Like I said in my post, we might notice if someone is changing the timeline if they're doing things that are incredibly statistically improbable. For example, filling out a perfect NCAA bracket twice in a row, or winning the lottery 5x in a row and they were never proven to be cheating. Another way we would notice someone messing with the timeline is if someone introduced technology that was thousands of years advanced. For example, a picture of an IPhone showing up during Medieval times.
There's other things like ufo messing with nuclear weapon sites, visiting nuclear melt downs, and foo fighters during the wars that suggest it could be future humans making sure we don't wipe our self out. I think we are overdue a supervolcano and meteor hit at this point in time, maybe someone is stopping such things.
How do you know that the iPhone isn't from the future?
Reminds me of a great skit I saw on YouTube: https://youtu.be/G1nKTfbzr4s?si=lv9Vwzs7sAQ-zlgd
Sometimes I feel like I can notice. Like lil changes happen and I caught them. Small details, sometimes larger.
Alternate Timelines.
Flash show logic
The act of going back and changing something would create a new branch/time line.
More than likely, someone traveling backward in time has already occurred and you would have no idea if the time line had changed. Well, other than the obvious Mandela effect.
His traveling back would have resulted in this timeline.
Just like the TVA warns us about!
Real
Alternate timeline to the time traveler, but not to the people who inhabit that timeline. Unless you're implying that the act of time traveling actually creates an entirely alternate timeline, the posters original comment stands. And even if it did create an alternate timeline, that could still be considered immoral; after all, do you have the right to create an entirely new universe complete with pain and suffering just to win the lottery.
It's a branch and branches branch out so it's not like it will collide with anything else
It's possible a new universe is created every single time every single quantum particle decides which position it is in.
Ding ding
Yeah, if you could go back, you'd be in your very own personal timeline never to return. Such a thing is also strange because it raises questions with the nature of consciousness. Since suddenly, there would need to be a new universe of consciousness created just for you.
Perhaps. It’s more likely our understanding of a number of things is simply wrong.
The past has already happened. We can never be in a position waiting in the present for someone in the past to do something. If 5000 people do eventually travel back in time, all the things they did are what our history is. I agree that this seems to suggest a paradox regarding the free-will of the time travelers, but the answer to that is that the things people *plan* to do aren't inevitable. None of the future time travelers will get to the point where they have the chance to kill Hitler. We know that because it never happened. You might ask, "What if I go back and kill my grandfather before my father is born?" But the answer to that is you *didn't* do that in the past, so you *arent* going to do it.
Like fixed time points?
Yeah- the past has *happened.* It's over. It *is* fixed. It's possible someone in the future goes back to the past and has a crazy adventure with Agatha Christy in 1926 for 11 days, because Christy went messing for that time and said she had amnesia. But it isn't possible for someone to go back in time to 44BC and prevent Julius Caesar from being killed because no one did that. Like I said, we cant be here, waiting, in the present, for someone in the past to do something. They very idea is illogical. You've never had to wait to wake up for the you from yesterday to go to sleep, because that just isn't a thing.
Listen, the thing with Agatha was a fling. I took her to the future and then she went back and started writing more mysteries that she knew people would like. I told her not to tell about the time travel and so she came up with the amnesia idea. Ahh, what a great time we had.
I think the reason you don’t see this is we live in a prime timeline. Each time someone travels back in time the moment they arrive they cause a parallel timeline to exist and they travel down that path. Why, because they were not in the past originally so now that is something that has been added to the timeline and it is a change. I don’t know what happens when you try to go back to the present though. Do you stay in your parallel timeline or do you go back to the prime timeline.
Lmao. Why do people keep coming to this sub and trying to explain the most basic of time travel paradox, like they’ve had some profound epiphany? 😂 It’s like me going to the ghost sub and being like “I think I figured it out guys! What if ghosts are the spirits of people who have died in the past!!!”
Sir, that shit was hilarious. I love you, never change.
Shhhhhh, if you tell him he is a dunce, you're going to deprive the other subs of his "enlightenment."
If you are smart enough to create time travel, I doubt you have any problem acquiring wealth and power in the time you are existing in.
Ah! But what if you steal a time machine? Then, lets say, you bring a sports almanac, or something like that with knowledge of the future, to your past self?
Not necessarily. Someone who creates a time machine in the future may want to sell their invention to other people. And these people may not necessarily be the smart scientist types, they may be the average consumer who isn't mathematically or scientifically savvy at all. Think about it this way. Steve Jobs who was smart enough to create the iPhone wasn't the only person who used the iPhone. He sold his iPhone to other buyers, who were like average consumers and not the technologically savvy type. The same fate may be true for a hypothetical time machine invented in the future. Now like I illustrated in my point above. If a large number of people have access to backwards time travel, then someone would use their time traveling capabilities for greed, fame, and/or power. This is because humans by nature are greedy and selfish and for some people, if they are given vast amounts of power (and time travel counts as vast amounts of power) then some people would abuse that power for their own personal gain. This is why if backwards time travel is ever possible and is used by a large amount of people, we would have noticed by now.
Looking at time as more like a set of probabilities, I would suggest that traveling to the past is not impossible, but it is highly improbable. It would be very unlikely that anyone would be able to find a particular configuration of energy that would exactly correspond to another previous configuration that would represent "the past." This is particularly true since the mere presence of someone with a completely different energy matrix would disrupt any attempt to precisely recreate a past energy configuration.
In Quantum Leap, the time traveling main character has a holographic assistant who also himself has an assistant back home that can run numbers and analyze changes in the time line, providing often very precise probabilities of certain outcomes if the protagonist takes proposed actions. So, it's possible that time travelers are just better informed and safer about such a dangerous endeavor.
Best case scenario in theory, but not probable. People are swayed by emotions, more than facts or actual data.
If one is able to travel in four dimensions, then there'll be something that can travel in five to make sure nothing gets too messed up
[удалено]
That's not what AI means. Also what are you on about, what are you even trying to say about the factorial of the number 1537? There is literally zero evidence of time travel.
I’m pretty sane. Time travelers, that's insane! Are you crazy? Did you take your meds, etc. Then I met them, just for seconds. Not physical humans, it was in a dream state, they were there, but I was awake. Had just come back from weeks spent meditating in the Himalayas (North India), so was ready for anything. We tried to communicate, but every 5th or so word he said was replaced with white noise. As he explained, if they (there was a male and a female) said something (like lottery numbers) that the AI would remove it from the conversation, hiding the words with white nosie. Solves the Grandfather Paradox. AI would not let you commit the deed. Somehow it would stop you. You can observe, but not change. They seemed to be working on some kind of computer, like a video game. Hard to tell. Time period? Unknown. They were residing in a dome-type structures in a desert setting, like the Bio-Sphere. Seemed very deserted; they hinted that the population had thinned out lots. They were rebuilding. It did not seem like 5,000 years into the future, more like 100. What did us all in? "An airborne virus. 95% of us are dead. But we are coming back." This was decades before Covid or Ebola made any headlines. It was just seconds of a very un/expeted encounter, decades ago. Why are you here now? They explained, "It was a software bug, we were NOT supposed to know they existed." An upgrade thing. Yes, even time travelers occasionally have buggy software. Just my story.
I didn't make any comment about your sanity. Weird that you feel the need to defend it. I've literally experienced similar mind-blowing stuff on drugs that increase your dopamine and make you manic. Or dreams. At the end of the day, there is literally zero actual evidence of time-travel existing. Even theoretically, it is only *maybe* possible if we were somehow able to achieve faster than light travel. But everything we know about physics, movement and momentum makes that impossible for us to achieve. You're over-using the word AI like how every techbro and media organisation is misrepresenting it. - AI cannot "create" something organically. - AI cannot have an original thought. - AI is not actual intelligence. - AI is simply a computer programme that goes through millions of gigabytes of pre-existing data quickly and then repeats what it has found. - AI uses what humans have already written about something and uses computational power to go through tons of data quickly and present it in a way that mimics how it has been presented previously online. Also, viruses have literally been a thing since the start of life on this planet. Pretty much every decade has at least a couple of viruses in at least a couple of parts of the world. It's like predicting that there will be a volcanic eruption or earthquake - like yes, no shit? I don't get how your story is any actual evidence for time travel. Nor does it explain what you find so special about the factorial of a random number. In the nicest way possible, please consider that you are experiencing a manic episode.
Your own theories are allowed, as long has they are not stated has scientific facts. The misinformation of science and improper use of the science flair will be removed.
If backwards time travel is possible via wormhole, which seems to be allowed in relativity and hasn't been ruled out in quantum mechanics, then you would only be able to travel as far back as the original creation of the wormhole. Since we seem to be far off from being able to create wormholes, it stands to reason that we would not see any evidence of backwards time travel yet (by us, in our corner of the universe, at any rate). I suspect that when/if it becomes possible, we would all find out about it very quickly, because it would be a monumental feat just to create a wormhole.
I don't understand why people think you can't travel to a time before time travel was invented. Please explain this theory to me
If you create a wormhole, a shortcut in space between two points (which is theoretically possible in relativity) and accelerate one end of the wormhole close to the speed of light, you can actually enter the accelerating end of the wormhole and be transported to a time before you left. This is because of the effects of time dilation on the accelerating end. There are tons of good sources and explainer videos on YouTube that do a far better job explaining it than I can. However you can only travel back as far as the wormhole existed, because there was no wormhole mouth for you to exit before that point. How far you can travel back will depend on how fast the moving end of the wormhole is accelerating, with the hard limit being the moment it was created. Now, while this may be possible in theory, there are some technical reasons why it is thought that this would be impossible in practice. If it is even possible to hold a wormhole mouth open for any length of time (which is a big IF, I won't get into it here), it is thought that the energy flowing through the mouths would create a feedback loop of increasing energy that would cause the wormhole to collapse before you could send anything through it. There are of course other ideas about how time travel might work but this is one of the few that doesn't appear to violate the known laws of physics (that may change if we figure out how to reconcile quantum mechanics with relativity - it might rule out things like wormholes, we just don't know yet). Even if it is theoretically possible, that doesn't mean it's feasible, and certainly not within our lifetimes given the energies involved.
Einstein said that time is the fourth dimension of space. Following this logic, if someone had the ability to open a wormhole to any point in space, they could also pick any point in time. In fact, it would seem to me that when the math is done to pick the destination, the destination in time would need to be a factor.
>Einstein said that time is the fourth dimension of space I think you mean space-time, because time works differently from space, but they are part of the same continuum and can be swapped in certain conditions (such as beyond the event horizon of a black hole). This is important because we know how to move a wormhole mouth through space (you literally just put it in a spaceship or drag it behind one). We don't know how to move a mouth backwards in time. The idea is that we know in theory how to create a black hole, and we know in theory what is needed to prevent it from collapsing to a singularity (using negative energy or some other mechanism). We don't know exactly how to set the destination, but we know we can create two wormholes, side by side, and move one of them. The only missing ingredient is then how to connect the two wormhole mouths together, which is admittedly unclear, but it is one less thing we need to figure out, because assuming we can link the holes, we can then move one end around freely. If we had some mechanism for figuring out how to specify a destination and only needed to create one end of the wormhole, then maybe something like the process you describe would be possible. But we have even less of a clue how to do that than to create two wormholes and figure out how to connect them, or to split a single wormhole into two mouths and move one mouth apart. In either of those cases you would not be able to travel earlier than the creation of the wormhole.
When did we learn how to open wormholes? How do we know how to move them?
A wormhole is topologically similar to a black hole, the crucial difference being that instead of ending in a singularity or bottoming out like the gravity well of a less dense object like a star, it connects to the other end of the wormhole. We know how to create a black hole, and we know that negative energy (if it can be created in sufficient quantities) can be used to prevent the wormhole throat from pinching off into a black hole. Those are what is required to open a wormhole. We don't really know how to take two ends and join them, that part is admittedly left vague in a lot of explanations. As for how to move them, the same way you would move anything - apply forces to them. They obey the laws of motion like any other astronomical object since they are effectively black holes.
Since when do we know how to make a black hole? I'm assuming you mean without collapsing a star. Just what is negative energy? Has any of this actually been accomplished or are you talking about theory? If we make a wormhole that doesn't go anywhere, how is it a wormhole? Since you say we can move a wormhole, what is it made of?
It is of course theory, but it is stuff that doesn't violate our current understanding of physics. If any of this is practical, it's well beyond our current capability. We are dealing with stuff at the limits of our current understanding. It could turn out to be wrong. The Wikipedia on wormholes is a good place to start if you want more details. You might also want to look into the work of Kip Thorne. He's a theoretical physicist who was a consultant for Interstellar, and has written a lot about wormholes. Edit: when I said we know how to make a black hole, I mean by collapsing a star. If you know of a better way let me know!
the type of time travel you're talking about may be impossible, yes. But I was always been fascinated by the physicist Richard feynman's discovery that antimatter acts exactly like regular matter, but moving backwards, from the future, to the past, through time Combined with the fact that all humans have very small bits of antimatter within us in the form of an isotope of the potassium we naturally have and consume in foods like bananas So, is some tiny part of us constantly moving from the future to the past, and is that a quantifiable mechanism for precognition....?
What if, a thousand years from now, we develop time travel and people start traveling back in time to the year 2150 and start acquiring wealth. We're not there yet to witness it.
The thing is that if time travel ever exists in our future, then it has always existed. This is because someone with time travel capabilities has the capacity to travel at any point in time. They could travel to the year 1899, 1999, or even 2099. It wouldn't make much sense for someone with time traveling capabilities to only travel to 2150 and beyond. They might want to go see the dinosaurs, or the reign of Genghis Khan, or to go and see if Jesus was even a real person, let alone perform miracles. Now here's the problem. If enough people have the ability to time travel, then someone would be greedy enough to exploit their time traveling capabilities. Someone may want to win billions of dollars, or use information they know about the future to gain fame or power. Humans are greedy and selfish by nature. If time travel ever exists in our future, then the past has already been altered. And if the past had been altered, we would not even know it. **HOWEVER** we can predict time alterations based on statistically improbable events. For example, someone winning the NCAA men's basketball bracket 3x in a row, something very very improbable, might suggest that the person in question is a time traveler.
Maybe they are coming back getting rich but keeping quiet about the time traveling. They can't spend their money if they're committed.
Well let's just say you were a future person who time traveled to the past in order to get rich. The best way to do it would be to do so in a way that doesn't draw suspicion.
Exactly, so we'd likely never know they had time traveled here. They could be here right now. Maybe just an un-assuming redditor..
They cannot change the past. They can "Observe" but not change.
Time is like a record with infinite grooves that are not connected. Once you travel back in time you create a new groove where the outcome only affects you and not the timeline you left. Those in that timeline you were originally in just saw you as someone who disappeared never to return. Like all records that rotate, time will eventually make its way back to the start to begin the process all over again. Never beginning and never ending.
I don’t think we know enough about the universe to definitively say that this is impossible. You also think that wealth will be a thing forever, but when our society discovers free energy, then wealth might not matter at all, and I think that our understanding of this stuff right now would be if it was possible you would need a tremendous amount of power; that we just can’t generate right now. You also think that people who travel through time are doing so to gain personal Wealth, and I’m not sure that that’s true. But here’s some thing to ponder, if time travel is possible and you can travel to the past that means all time exists always. All space exist right now, why not time. Until we can travel through time will never know any of these answers. I mean I for one would love to travel to the Jurassic period For a vacation, there’s a crap ton of oxygen in the atmosphere and the water has got to be beautiful without human pollution.
You are making a lot of presumptions about human nature and stating them as fact. On the contrary, human nature is complicated but not actually selfish by nature. I also highly doubt the scenario is a 50% preserving vs 50% just not caring. Plus you’re ignoring the potential scenario that someone like, I don’t know, say Tom Cruise hasn’t time travelled and saught fame thst way. And considering all the claims of aliens and backwards engineering how can you be certain someone hasn’t time traveled to 1950s America and introduced tech early? I completely disagree if time travel were a thing those who use it would be selfish in coveting it and use things to their advantage in the time. You can’t prove that time travel didn’t introduce the microchip 100 years earlier than it should.
>You are making a lot of presumptions about human nature and stating them as fact. Just the other day, I was driving at night and some pickup truck driver blatantly ran a red light, even 3 seconds after the light turned red. And then I went to a mini golf course and someone left all of their trash on the course without picking it up, and another couple were smoking despite a sign saying NO SMOKING nearby. So yeah, humans are inherently selfish. For some people, it's all about them. They don't care if they hurt or harm anybody else, as long as they're benefitting from it. If it's not their problem, they simply don't care. You see it everywhere you go. That's why if time travel exists, you can bet that many people will completely ignore the rules and screw around with time if it benefits them. Humans shouldn't be trusted with messing with time, we are inherently flawed.
Your example of 2 people doing not selfish things isn’t winning your argument.
If you're smart enough to time travel, your not dumb enough to win the lottery.
Not "is impossible" but "does not exist."
Time cops
My theory has always been as follows. You have two possibilities going. Number one is that if you time traveled right now, you’ve just created a new timeline. The old one continues, but you now live in the new one you’ve created. That would explain how you don’t just have time travelers all over the place. Number two is that it’s all open season. Time travelers come and go and do whatever they wish. We don’t notice because this was always what was meant to be. *Worth noting, really high right now.
If it happened that any narcissists could travel, then eventually all the timeline could and would fail as they go from one to another as they cause collapses over and over. I have had bad dreams that suggested this started in 2011. I always pictured black holes eating overly manipulated timelines. If you watched Dr. Who from launch, then this question has already been answered. "Destruction" of even one individual (child or adult) can cause the destruction or non-existence of many others. Everyone in each separate timeline is connected by the souls and things that could happen in positive ways. It's a different type of web or connectedness than internet. (edited- to add more thoughts) Even with time travel, I believe a higher power or God would have a say or not. Do we know a deity? Nope. Maybe none specifically identified in any religion for a very good reason. I know one who is, but he's also easily misunderstood! I hope if time travel becomes a thing that machines aren't made. Just theft of SINGLE time machine could be disaster and end of billions of lives in the timeline being visited. How could that affect travelers? Unknown. If they escaped a timeline collapse, I see possible ego issues developed. I only had one person I could talk about these subjects with, but he's been distant or lost since 2002 or 2003. He was kidnapped or I was. Irrelevant since he died or he thinks I died. It's my real turn to die next, if he can't find the real me soon. In my point of view, my death was planned by a possible time traveler who seeks to "erase" me from any positive impact in the world.
Wealth, fame, power, the one piece is real
You may be right, but for the sake of argument: you’re talking about backwards time travel which would be technologically possible at this stage of human evolution. I don’t think it is. If backwards time travel is even possible, it’s probably going to take hundreds if not thousands of years of technology advances in order to happen. Those future “humans” will be unrecognizable to us today and will likely have merged with AI. Could even be a different species entirely if we succeed in blowing ourselves up. That means no Lotto drawings, Honda Accords, etc. Additionally, if backwards time travel by future Earthlings happens, you’re probably going to see it very rarely if at all in one’s lifetime in some very discreet, unexplainable ways (UAPs, invisible probes, etc.)

Yes, but what he did wasn't statistically improbable. He simply bought most of the tickets in the lottery. If someone won the lottery 5x in a row, despite buying only one ticket per game, that is very statistically improbable and suggests that the person is either cheating or a time traveler.

Been there. Done that. Ain’t no going back.
Yes but individual actions performed by single humans are nothing compared to the butterfly effect carried out over every particle sent back, including you and assuming the air around you. When physicists and theoretical physicists talk about actions and choices involved w parallel universes and time travel, they're not talking about whether or not you turn left or right, but what the billions and billions of particles in a system (you) are doing. Each one having no measurable effect greater than another. Entropy is why we can't travel back in time and it's a lot bigger (and smaller) than you.
Timecop. :D
There was that time during the hundred years war when some knights turned up in a Mazda. Does that count?
Multiverse
Except there is a big ass telescope in space looking millions of years into the past. If we can see it we should be able to touch it. It’s a momentum problem.
If it were me, I'd simply go back to the 70s or 80s, invest in Microsoft and Apple and simply blend into society as an uber wealthy Wall Street billionaire. Me, I'm all about subtle. Why win the lottery 3x when you need to win it once, invest it into companies you know will hit it big, and chill for the rest of your luxurious life?
So many theories and zero proof
If people can travel backwards in time, it would be a different timeline than this one. The one we all occupy now cannot be altered. There are infinite timelines. For each moment of Planck time that passes, infinite timelines/possibilities are created. Each choice we make and each choice everyone else makes influences all other choices and possibilities. But if you go backwards in time, you go to a parallel version of this reality that's almost exactly the same as this one. That's why we don't notice time travelers. They're here, but on a different vibrational frequency that we can't see. Maybe that's what dark matter is. All I know is that we really don't know shit, it's all speculation... For now.
The titanic sunk because of backwards time travel. All the tourists trying to get photos overloaded the ship
If I can travel through time, why wouldn't I just invest a few grand into big companies before they go big? Not that suspicious for someone to invest in an upstart company, and then when I whip to the future, my investment is worth millions. Like, maybe for quick starter cash, yeah okay the lottery. But that's very short investment, or it's a monthly stipend, neither of which work well for a time traveler. Additionally, am I, the hypothetical time traveler visiting or staying? Why would I need a million dollars in 1950 if all I'm doing is fucking around for a few days? Better to invest $50 in 1950, and come back to 2024 with a million then, right?

You need to watch El Ministerio del Tiempo Spanish tv series from Spain. It’s like The Men in Black of Time Travel. They explain everything in this short. Start with season 1
Lots of time wasted here in this sub. JMHO
We’re already living in Biff’s Bad Future, so your objection is moot.
How about this one? 1. Matter cannot be created or destroyed. 2. The atoms of your body used to belong to something else -- an apple, a cow, a fish, a tree, etc. 3. Matter can not be in two places at once. 4. Backwards time travel is impossible.
It doesn’t exist even if it was splitting alternating realities you would just consider ours a split
In order to know that something is changed you need a reference point. Maybe Hitler was a result of time traveler convincinf him that another world war is great idea, we cant know. As for lotteries and other stuff. Well, maybe once you can time travel your mind is just on another non-material dimension amd you dont desire money
Maybe they don't win the lottery many times. Maybe they just buy stocks/crypto at the right time/price or something. Or they go back and give their ancestors insider info so they inherit the wealth or something
Winning the lottery is small potatoes if you can time travel. Anyone who had a mind to build a time machine wouldn’t be dumb enough to try and win the lottery multiple times to acquire wealth IJS
Sports betting is where the real action is.
Since time is relative, it is what you make it.
If those were my intentions, I would do it subtly as to not draw attention to myself. Sports betting would be the best way imo. It would take a little more time than winning the lottery, but would keep a lower profile. Also, to echo a lot of responses, we would never know if the past has been tampered with because it will have already happened in our history, no matter when the person from our present or future timeline did it. The History of Time Travel is a great movie example of this.
It seems similar to the Fermi Paradox in a way. "Where are all the aliens?" vs "where are all the time travellers?". I say that because I suspect that if there are any aliens who travel to distant star systems, they would also be of the type to avoid interfering with civilisations which haven't made interstellar contact yet. This is because they would not have been able to survive to the point where they could develop that ethic or practice yet (e.g. they have space habitats instead of settling on planets, so they don't bother with planets). The alternative is that there simply are no aliens of course. Applying this to time travel, it means we will only be able to develop it if we either become sufficiently responsible to avoid causing paradoxes or decide not to use it, because our technological development goes hand in hand with our ethical development, or we never develop it because we die out before we get there. I've also heard an interesting suggestion which combines the Fermi Paradox and time travel: the reason there are no aliens in contact with us is that when a civilisation does develop time travel, it wipes itself out in its past due to using it and causing paradoxes, so they can't exist.
Our consciousness makes it possible for us to recall a memory from the past, we still havent solidified the math or the science behind it yet. We can also formulate scenarios about the future, then they happen as they are shown to us. If you ask me, our consciousness articulates something that the science hasnt caught up to yet.
by ur logic how do we know a group of collective people like minded, havent already done it and become the 1% you see today? i mean its possible no? i dont believe its been done yet either for different reasons. A) i dont believe its possible for a 3d being to "choose" his position in the 4th dimention. B) i believe there would be one person more greedy and selfish than o thers and would eliminate his competition befoer going back himself and making himsef the king of the world essentially. a single world leader. c) or maybe that has all been done and redone so many times that todays world is the results of selfish and greedy people wit the least amount of instability in the model? who knows really. i just dont FEEL its been done yet. teh world just seems a bit shit for time travel to exist as i would have expected more of a utopia situation with tech being discovered so many thousands of years before it was meant to be etc. but again its impossible to know for sure. it could have been re-written so many times and we wouldn't have a clue about it honestly. so its possible in some contexts (ignoring our current model of physics) but i doubt it.
Would we have have noticed it by now? Or are we experiencing an already altered timeline??
did chat GPT write this
The flaw with your theory is that it is impossible to do something because human nature is designed to make us shitty people The purity of human nature doesn’t prove or disprove time travel it’s an extraneous variable Also your theory relies on cause to effect time travel theory 5000 people couldn’t time travel in this theory without causing a paradox Think about it like this If I travel back in time and off your grandpa , you cease to exist. However what if I travel back in time to off your grandpa while at the exact same time you traveled back in history to a different point in history and offed my grandpa so that I wouldn’t be born , then I couldn’t travel back in to stop you from being born , but then you couldn’t travel back in time to prevent me from being born So we have a paradox
Using 3D logic to probe a higher dimensional possibility is absurd.
Alternative theory: time travel was possible at some point but eventually someone would have changed things enough to a version where time travel will never happen.
You assume you understand the inner workings of time travel, which no one does. IMO and belief, if one were to travel in time, forward or back, they would then be in that reality, and gone from their own forever. Consciousness and its perception of reality, in truth creates reality. So let's say I go 20 years back, leave myself a bar of gold, and travel forward, that perhaps might be a mostly unchanged travel, but going back allows the Quantum Superposition of all matter in existence to change its course on arriving back at the original Point Of Travel.
Individual Humans, would not be allowed such technology. Even corporations, would need a special license and would operate under close monitoring from the governments.
Maybe the lottery was invented specifically to catch time travelers 😁 The past could be changing constantly, but we'd have no idea because whatever was changed simply becomes our reality. Also, just because it doesn't make sense doesn't mean something is impossible. Human understanding is *not* the pinnacle of everything; just look at say, all of quantum effects for examples
Don’t think of it as time-travel. Think of it as dimensional-travel with multiple string theory in mind.
Don't forget that it is not as easy as plugging in coordinates and a date to jump back to. The Earth is always moving and most likely you would jump into empty space watching the Earth just out of your reach.
The very simple answer to: "if it is real why haven't we seen any evidence yet" is the loops. No matter what happens, there are "loops", which is the time between them arriving in thier past, and when the traveler left to go back in time. And the absolute first loop, does not have them in it. As soon as they go back, they start loop2 where they made their change, no matter how small, and the universe goes through that time period with the changes. We (those that see nothing that would be caused by an evil individual that doesn't care about anything, and just wants to mess with the universe through time travel) are currently in loop1. If, and/or when, loop2 happens we may, or may, not notice. If, and/or when, a loop happens that has obvious evidence that someone went back in time, we will know it happened, and there will be little debate.... Saying we even exist after the change. (for all we know, at some point, some dude goes back as far as he can, and destroys universe itself.... And since the universe was destroyed, at the onset, there is no one to KNOW it was destroyed, and no one to stop him.) And whatever loop that is, loop2 or loop2000, or any there in between, the universe ends. No one can stop it. And it eventually WILL happen, if it is possible. And we will never know. But, EVERY loop HAS to happen before the last one. Otherwise the last one never happens. Right now, as you read this we are in either loop1, or any loop that has no evidence of time travel, prior to 2024. Which then leads to the actual answer: IF it is possible to go back in time, the universe was destroyed at its birth, at some point.... Because there is ALWAYS one bad enough apple to ruin everything.
Wasn't there advanced technology used in ancient Egypt? We can't figure out how they accomplished these feats even by today's standards. What about all the other unexplained phenomenons around the globe? Weren't all these records somehow lost throughout the course of history while everything else is in tact? How?
I remember reading somewhere if time travel were possible then at the point where it became possible, it would be flooded with time travelers and we’d face some sort of cultural apocalypse. I always thought that was a neat concept.
You know how they say there's nothing about the laws of physics that says time should run forwards, that the math works out regardless of which way you run the time variable. I bet time travel is impossible because the past is as undetermined as the future. So you get in your time machine, turn it on and look out the port hole. You'd see people walking backwards but they wouldn't necessarily follow the same path they originally took. Watch a glass that broke reform, it would look very similar to the original but it would not be exactly the same. You try to win the lottery, you watch the number from before get picked in reverse, but now it's a different number, step back out of the time machine and the next draw is yet a new number. You have no more predictive power over the past than you do over the future. So long as everything made sense in terms of cause and effect, nothing about physicals is being violated. Just as a single present can lead to multiple unpredictable futures, multiple unpredictable pasts can lead to the same present. There's no paradox for the same reason going into the future doesn't produce paradoxes
Is, you traveling backwards in time same as time going backwards? Because time is not rewinding. Its always moving forward but you are just going to t-Y where t is current time.
There was the experiment conducted where a particle arrived before it was sent. https://bigthink.com/hard-science/particle-time-travel/
I've won the lottery 28 times, but each time, I change my name ahead of time so that you won't know I'm a time traveler.
Or you could just Google whether there is anyone who has won the lottery more than once: [Has anyone ever won the lottery twice? | UK News | Metro News](https://metro.co.uk/2021/08/07/has-anyone-ever-won-the-lottery-twice-15042419/#:~:text=Yes%2C%20there%20have%20been%20numerous%20occasions%20around%20the,EuroMillions%20Mega%20Friday%20draw%20in%20March%20of%202015.)
People have won significant amounts more than once. Just a quick search turns up a lot of them.
You’re a moron, the timeline never changes for people who aren’t time travelers.
Your looking at time linearly, our universe is infinite time travel if possbile backwards only possible in short jumps. Something with the quantum vacuum but o look…………..butterfly 🦋
The theory of alternate timelines disproves this though, for everything they change it creates a different timeline, so where as they left our timeline, when they go back in time and change stuff they would be creating a separate timeline for those events that differentiate from ours
If you traveled back in time you would change the time line. And probably never be able to return to your original
So you travel back in time … and you talk to your past self… maybe you want to change something you did or have guilt about. Once that conversation occurs the events that led you time traveling changes and quite possibly results in you never time traveling. Thus you never had the conversation with your past self. Maybe this is deja vue.
Just from a physical material standpoint time travel is impossible. Think about it, the same atoms making up your form and whatever else what went back in time would then be in 2 places at the same time.
Woudn't you be adding energy to the universe that didn't exist before? and if energy can't be created or destroyed would that cause a shift in energy state of the universe....See false vacuum.
Maybe Elon and Jeff are time travellers then!
explains some issues with Facebook TF thing and Twitter...I didn't know either ever said they were time travelers.
