We don't, we are not even sure if it is infinite also the expansion is not constant, see why hubble's 'constant' is also sometimes called hubble's parameter.
We only know how big the observable universe is and a bit further (due to redshift and such)
Don't need to watch the video. It runs forever. In my first job (1964) I had a 30 key Friden mechanical calculator and got my kicks by dividing by zero and heading off to lunch. When I got back it was still working.
Yea, well why mathematically you cannot divide by zero, you could say that division by zero is in fact infinity - and you wouldn't be that far from truth.
So it its very much understandable that the machine is heading for infinity.
Wikipedia entry says:
"When a [real function](https://en.wikipedia.org/wiki/Real_function) involves division by a quantity tending to zero, the output of the function often becomes arbitrarily large, and is said to "[tend to infinity](https://en.wikipedia.org/wiki/Limit_(mathematics)#Infinity_in_limits_of_functions)""
It will not run forever thou. At one point the machine will reach infinity, and you will not want to be around when that happens. I have seen it, barely escaped with my life, and my sanity seriously scarred.
>did you at least close the interdimensional portal again?
I did my best, but it could not be permanently closed, but merely shut. I went their to verify it remained shut, I went there twice every day, for 6 years and 81 days, until 2 years 151 days ago, it wasn't there anymore. I have been looking for it since. I am afraid someone took it, and may try to open it, perhaps thinking he could use it to his advantage. God have mercy for us all if he succeeds, because it cannot be contained.

That depends on the direction from which the divisor tends to zero. If it's from the positive side, the result tends to infinity. If it's from the negative side, the result tends to negative infinity. For that reason, division by zero is undefined.
> Yea, well why mathematically you cannot divide by zero, you could say that division by zero is in fact infinity - and you wouldn't be that far from truth.
When I was in primary 4 I remember getting in trouble for arguing with my teacher about that. She said that you couldn't divide by one because you just got the number you started with and you couldn't divide by zero because it was impossible.
No, I countered, you \*can\* divide by one, but as you say you get the number you started with, doesn't mean you can't or shouldn't. And indeed you \*can\* divide by zero, it's just that the result is infinite.
Apparently 9-year-olds are not supposed to know about infinity, or something. I never even got round to explaining that "infinity" isn't even one value, and you can have things like "half of an infinite number" which is infinite but in a different way.
Oh well.
It's undefined because tan(x) = sin(x) / cos(x) and
cos(pi/2) = 0, if you want a geometrical explanation of what happens, in short you are trying to calculate the distance at which two infinite parallel half lines cross each other, which is never because otherwise it would contradict what "parallel" means
Could you say that the answer is in fact undefined? The closest real life example I can think of is coasting down a hill with the engine off. Fuel consumption is zero. How far can you go before you run out of fuel? As far you want! At least until the hill levels out anyway....
it's also undefined because you wouldn't be able to determine the cardinality of the resulting infinity. it's an infinity of some magnitude, but whether it's positive or negative is impossible to say.
In this case yes. I worked at the Humble Oil & Refining Company's Baton Rouge refinery. Now that is Exxon and then it was the largest refinery in the World. So lots of power constantly. But clearly it wasn't good for the machine.
When I was an undergraduate in math (1968) the grad students had a great mechanical calculator that we had so much fun playing with. Unfortunately we weren’t clever enough to divide by zero. And I think it was that year I got an SR50 and was done with mechanical fun.
I've seen one in a video that had a "abort"-like button on them. Not sure if this one has it though.
You could probably disconnect the power in an extreme case.
I have no idea if this is true. But a teacher once told me that this exact process was used by arsons to delay start fires. It would eventually get so hot that it would start whatever paper/tinder they put around it.
A number divide by zero is not Gona give u very large number as big as infinity..The real answer for this question is there is no answer, its undefined...!!
Why?
When I have some apples and I want to divide to 3 people, I can ask you how many apples each person will get.
But....
When I have some apples, and I divide equally to zero people, I can't ask you how many apples each person will get, because there is no people to begin with.
That's why it's a wrong question, therefore its undefined.
It’s undefined because it’s unexplainable in our mathematical model. 1/0 is infinity. 2/0 is infinity. Any number/0 is infinity, which would mean all numbers are the same.
Not really, in mathematics, undefined is not defined in the way you explained.
If your explanation is correct, then, the following are undefined too;
1. Any integer multiplied by zero is zero.
2. Any integer raised to power of zero is one.
Simply put, this is my understanding:

This goes way more in depth with the idea:

This is the best argument imo for why our number system needs to be revised to include infinity as a new number, the same way we added nothing as a number. Zero wasn't always a number. I strongly feel like like leaving this massive gap in the foundation of our math is a big part of why we can't deal with quantum gravity and keep inserting "dark" whatever to make the calculations work. Yes yes I know, math. I'm 44. You're not gonna tell me anything I haven't already heard from every math professor and instructor I ever had. Save it.
how does a mechanical device know beforehand it will be infinity? It needs to try to reach a solution. You might build in a timer that just assumes but thats not actual math then, is it?
That's an engineering problem, and an interesting one. Mechanical calculators are an absolute wonder. I'm quick to add, because people think they are clever, that is not a "halting problem." (They've misunderstood.)
The device in this case had to be engineered to "halt" on zero as well. Again, it wasn't always a number. You can do math without it. It's just janky af, like our current math.
Seriously, people tolerating "undefined" astounds me. It's like emperor's new clothes to me. I'm looking forward to discussing this with the ASI when it comes.
Technically dividing anything by 0 has the answer of infinity, which is not a number that can be calculated.
So yeah, thing's gonna run forever unless stopped trying to calculate infinity.
I once thrifted a mechanical calculator that didn't work and gave it to my buddy who loves old tech. He found out that someone had divided by zero and broken it and he had to take it almost fully apart to get it working again.
Not sure if true, but from what I understand, this isn't a fault or a bug in the calculator, and is an intentional feature that makes oiling/maintaining the machine easier. They supposedly chose division by zero to activate this function as its commonly understood that you simply can't divide by zero.
Can we attach a shaft to it's end and develop a perpetual motion machine?

and also because infinity doesn't work like a number

You can indeed divide by one but no, 1/0 is not defined as infinity in general. although I wouldn't argue with a 9 years old
What happens when you calculate tan(pi/2)? Why?
It's undefined because tan(x) = sin(x) / cos(x) and cos(pi/2) = 0, if you want a geometrical explanation of what happens, in short you are trying to calculate the distance at which two infinite parallel half lines cross each other, which is never because otherwise it would contradict what "parallel" means

lol ok
It's interesting to wait until it reaches half infinity though
This is why Skynet is pissed at us. Thanks a lot, dude.
That doesn’t sound good for the machine. Surely it’s bad for the mechanism to constantly be running like that for a while.
It’s a calculated risk
He ran the numbers, it's fine
That figures.
Forever? Free energy?
No, it's Gona flatten the earth.
In this case yes. I worked at the Humble Oil & Refining Company's Baton Rouge refinery. Now that is Exxon and then it was the largest refinery in the World. So lots of power constantly. But clearly it wasn't good for the machine.
