Any Physist that understandthe MATH in Einsteins theory of relitivity...or To be exact.

Well time and velocity and distance are related by the simple concept of v = d/t, where velocity is just the distance traveled in a certain amount of time. And Schrodinger mainly just proved a flaw in the idea of a superposition with the well known ''Schrodinger's cat'' experiment. Not much to do with time. It was mainly just how nature determines an outcome when an observation is made. Until it is observed it could be in several different states.

An interesting thing about Einstein's theory of relativity is how it seems to fall apart at the singularity of a black hole. The same laws don't seem to apply. If you're interested in physics I suggest you watch a few documentaries and look up a few of the basics, such as Newton's laws of motion, energy, forces such as the four we consider fundamental. It's an extremely interesting subject. It helps you understand how everything fits together.

I have an original text written by Schr- he invented the wave function to spit out expectation values before the theory was totally constructed. The cat is an analogy- a real world example to illustrate the absurdity of qm for people who didn't get it.

regardless time is usually needed.
Example
this one is really basic

S=d/t
speed= distance over time and vice versa depending on what your trying to find.

Time exists.
If it didn't everything would happen at once.

No, it wouldn't. That's because nothing could happen by definition.

In eternity, which is a state out of time, nothing changes because nothing happens.

I disagree.
Eternity would be infinite. Therefore everything would happen. All at once.

I'm not trying to be rude mate but it sounds like you need to understand Physics a little better.

Speed is equal to distance divided by time.

Distance is equal to speed multiplied by time.

And time is equal to distance divided by speed.

This simple triangle will help and its how most are taught.



As for your theory of replacing the time variable with speed. What then will you replace the speed variable with?

Some people think that time may however operate in a non linear manner which if found to be true would quite possible put a spanner in the works regarding the above equation.

Time definitely exists, as others have said, without it everything would happen at once.

The really odd thing I find about time though is the concept of Time's Arrow. Which is to say, there is nothing in physics that determines that time has to run in the direction it is running in, it could just as easily switch and run in the opposite direction, and physics would be fine with that.

So the question becomes, why does Time's Arrow point in the direction it points in? What causes the universe to unfold in this direction? And wouldn't it be theoretically possible somehow to reverse it?

"What causes the universe to unfold in this direction?"

Simple answer to that is expansion.

"And wouldn't it be theoretically possible somehow to reverse it?"

It has been postulated that if indeed the Universe starts to contract time may very well run in the opposite direction. I think Red Dwarf touched on this concept will hilarious results!

I would think entropy still happens at least according to our current understanding of thermodynamics. Also how can you have a state out of time? It's really all about perspective if you think about it.

reply to post by Painterz


Sure, the theory allows time reversal. This is tied in with allowing for anti-particles which can be described as particles traveling backwards in time. It is postulated that anti-particles are basically particles that have undergone a CPT (Charge, Parity, Time) transform. While not strictly relativity it branches from it.

The big point of interest is testing if this is actually the case. Which is currently ongoing, CP violation has been proven to exist at a small level in the hadronic sector. This means that anti-particles can exhibit properties that means that they are not an exact CP transform of particles. The Time part is not as easy.

It is interesting because It might turn out that the theory of anti-particles as being CPT transforms might be not quite right.

Sorry if people might think that is off topic but, i throw it in because of the whole time reversal thing... and i leave you with a quote

"Time is an illusion, lunch time doubly so"

lol.

Time is a "side-effect" produced by motion. Without motion, time cannot exist.

Initial conditions, apparently are lower entropy.

No.

No. By saying "everything would happen", you are insinuating 'something happening'. In order for 'things to happen', this is the definition of time, things happening. So if things happen, if everything happens, it couldnt possibly happen "at once", because that makes no sense.

Time is speed and distance and motion and vibration and movement and entropy. Time is how many times an electron vibrates in 5 claps compared to 10 claps. Time is how long of movement and space does it take for the earth to rotate once, time is how much distance of space coupled with the earths speed does it take for the earth to travel around the sun once, time is the length of interval before you feel hungry after eating, time is the transformation of energy.

Time does not exist. Want proof? Ok

The past has gone,the future has not happened,and the present has just gone.
How long is the present?

reply to post by symptomoftheuniverse


Time exists, you want proof? You have not always been alive, neither has your parents, or theirs, or theirs, or theirs. You will not always be alive. You go to sleep. You eat and drink. All of this is time. Time is nothing else but energy changing. Thats what time is. Does energy change? Time exists.

ok
Time is the perception of change. But it still does not exist. No observer/perception equals no time. How long is the present?

reply to post by symptomoftheuniverse


Time is only the perception of change? Not change itself? If you were in a coma would you not still die eventually, even if you could not perceive change, wouldnt change still occur? How long is what present? This abstract, human made concept and word present you speak of, consists of constant change...ya know, time.

you can only percieve change in the present. Someone in a coma is witnessed by someone in the present. The present is the only thing that exists and no one knows how long the present is. Its the thin line between the past and future. Everything we percieve has actually already happenend,in the past. No such thing as time.
