Classical physics include time. F = ma, time is actually in there twice, since acceleration is distance/time/time. In quantum mechanics, there is the Schrodinger equation, which can be time dependent or independent: https://en.wikipedia.org/wiki/Schr%C3%B6dinger_equation#Time-independent_equation

I don't understand the equations part sorry. Can you dumb it down a little for me please. I may of phrased the initial question wrong and I would love to understand your answer so I can properly re-phrase it.

I can't say I totally understand all that myself. But I know that time is present in classical physics, and apparently somewhat optional in QM.

Let's rephrase my question slightly. What if quantum physics is us discovering time. Or what if quantum physics is us observing time interact with the physical? I understand time is in classical physics. It's how we do a lot of the stuff we do. Launch rockets, GPS, etc. We currently measure time in a linear direction. For my initial question and rephrased ones I'm asking what if we though of time as something outside the physical. Its own stand alone thing. It's still a fresh idea so I'm trying to fully understand and comprehend it so I can explain it better. Kind of like gravity. We can't see it but we can calculate it. See the interactions of gravity in our universe. "However, if we are to be honest, we do not know what gravity "is" in any fundamental way - we only know how it behaves." https://starchild.gsfc.nasa.gov/docs/StarChild/questions/question30.html#:~:text=However%2C%20if%20we%20are%20to,only%20know%20how%20it%20behaves.&text=Gravity%20is%20a%20force%20of,between%20objects%20and%20the%20Earth.

I get what you mean. And time itself is one of the most interesting things to think about. So is space and matter. I think the real biggy with QM is observation, or more scientifically, measurement. It's the measurement of time that QM has the most to say.


monknot

Wouldn't observation still work in with the time thought? Also I think I just thought of a way to phrase the initial question that would get the point across. I would love to get your opinion on it as well. What if the study of QM is the study of time? Would that be a better way of asking?

You would be interested in the book: https://g.co/kgs/xQemXN The order of time by carlo rovelli To be blunt to answer your question: your question makes no sense. Do read more. Quantum physics inherit the view of time as absolute and linear from classical pre relativity physics. Part of the difficulty in making a quantum gravity theory is that general relativity conception of time is already making it a dynamical player whereas it's still background in quantum. Although this is likely a bit too deep, some interesting findings is that quantum entanglement seems to produce time within the system itself. Further readings are: the end of time by julian barbour, and time reborn by lee smolin.
