## If there was no motion, would we still have time?

How does science work? And what's all this about quantum mechanics?

### If there was no motion, would we still have time?

If yes, then how would we measure it?

What do you mean by "no motion"? If the entire universe moved one foot to the left, how would you know? How could you ever determine whether there was absolutely no motion?

For now, no motion within the universe. Assume that.

Consider the following mathematical function on the nonnegative reals, modeling time.

From t = 0 to t < 1, there's lots of motion.

From t = 1 to t < 2, there's no motion.

From t = 2 onward, there's lots of motion.

So if you measure at t = 1.5, there's no motion. And if you keep waiting, there's no motion. But the clock is still ticking. And then at t = 2, there's motion.

So yes, there can be an absence of motion and time keeps ticking.

Time still flows. Just look up the special theory of relativity. When you don't move through three-dimensional space, then you move through the dimension of time. If you moved as fast as the speed of light through three-dimensional space, then you would not move through the time dimension at all. I'm not sure why the special theory would no longer hold if nothing within the universe moved.

nope. if you could reach absolute zero all electrons with stop "orbiting" their atoms, and the atoms would also "Stop moving"

since we cannot reach AZ - it is impossible, just like reaching the speed of light (where energy can, but matter cannot ever do so) - where in both cases Time would stop.

but since we can't its only a theoretical matter and time marches forward and multiple speeds.

You do comprehend that for time to exist requires causality, ergo, without motion, a result of said causality, we would not exist, ergo we would not be here to measure it.

Ergo, there would be no 'yes'.

So Phil - you called me a fool and told me to basically bugga off to the Religion area - how about imparting your wisdom upon me here?
