I just basically have a question for the people on this forum who may or may not be smarter than me. If there were no motion or movement in the universe, would the concept of time exist? If the earth did not orbit our sun, the moon stood still, the earth did not rotate on its axis, would humans have a need to measure the length of the day? For that matter would life be possible without motion and movement in the universe, or would gravity exist? Just thinkin'......

No, humans wouldn't exist so they wouldn't need to measure time, gravity would be a moot point. If you want to explore, start looking at the experiments that are close to absolute zero. Since motion is a form of heat and visa versa, that would give you a little insight on how things would really be. What you are postulating would never occur.

0. Do we agree that time is artificial. We can measure it from our solar system or from something else.
1. Do you exclude waves from the set of objects that can "move"?
Now
2. If there were no motion would there be human life? because your blood has to flow through your body and you also have got to breath some oxygen to help your brain and your heart.Not to forget that signals travel through some canals to your brain this is how we interact with our environment.

3. If there were no motion would we be able to see with our eyes, given the fact that human eyes work on a certain light frequency interval ( the visible light). Light "travels" doesn't it ?

4.Suppose you exclude all the above from the concept of motion.
Let's try this: Do you feel tired when you sit in a close room where you do not see anything moving around you and do not hear anything? If yes, then we could use the extent of this tiredness as a yardstick to measure something we call time. See point 0.

5.Now let's suppose we exclude ourselves from the universe. I mean a situation where we can move but all the rest of the universe around us is in a standstill, would there still be time and gravity ?

In classical mechanics, gravity depends on what? Gravity itself is a vector field. And the force of gravity an object exerts on another object depends on the masses of the two objects and the square of the distance distance between those two objects.
F= GX(m1 X m2 ) / d^2, d=distance between the centers of the two objects, m1 and m2 their respective masses and G= the gravitational constant.

But there still would be a problem here because force F is measured in Newton ( from the fundamental principle of dynamics F =ma ) . In this principle there is a notion of motion as a is measured in meter meter per second squared ( m/s/s) Hence Time ans Space become interdependent.

I tried!

is the search of equilibrium the cause of Black holes , despite all the stuff people are saying

Time is the measurement between events. If there was no motion, there'd be no events, hence no need for time.

No. Time only exists in the context of motion. In some cases, time does not even exist, despite motion from some perspectives. E.g., theoretically, time does not exist from the frame of reference of a photon ( http://www.quora.com/What-does-the-f...oton-look-like ), and it might not exist below the event horizon of a black hole.

Life would certainly not be possible. As for matter and gravity: The fundamental elements of matter are intrinsically energetic, so I don't think that matter would exist without motion (e.g., electron orbits, quantum tunneling, etc.) If you allowed quantum motion but somehow froze the motion of all macro-scale objects, then gravity would exist, but then the objects would be falling toward centers of gravity, contrary to the proposed "no motion". To prevent motion, you'd need a force counteracting the pull of gravity, but what sort of force could possibly pull on every object in precisely the right way throughout the universe? And, BTW: In Quantum Field Theory, "forces" are generally "exchanges of virtual particles" so once again you have quantum-level motion any time you have any type of "force" at work.

The bottom line is that time, as we conceive of it, is an illusion. It's basically just a mathematical concept needed to account for changes in physical states. There might be some fundamentally qualitative proto-temporal aspect of reality - some "potential-for-qualitative-experience" built in to the fabric of existence, and "qualitative experience" seems to logically imply some sense of time (albeit illusory in some sense), so go figure.

Well, let's see... I'll just push the "On" button on this Universal Motion Inhibitor.
Okay... wait f <...pzzzzzzt...>

using you as a jump point. not sayng one thing or another about your premise.

Brian Greene is one of the leading theorists of string theory. He is an excellent teacher as well.

I don't know.

Stand still.

Does time pass?

No one, regardless of that which can be perceived, is really standing still.

If you stand still, everything moves around you, creating different events. However, if everything is still, no movement whatsoever, the idea of time disappears. Time is a concept created by man.
