the speed of time, a property of time?
1, uniform as Newton would like to agree, otherwise his motion formulas wouldn't be too accurate.
2, accelerated as Einstein's relativity theories imply. In Einstein's theories everything is ever-changing given different frame of references. The strangest thing about Einstein is that he thought that everything was changing except the concept of Logical Determinism.
I think the most interesting conjecture about time is that whether time has direction. By far, all the physics formulas involving time have no direction, which gives rise to the stories of time traveling.
As for possession of time, I don't think so either, but we do possess duration. I'm not 18 any more. It's truly a lamenting fact.
dE * dt > h implies that one of the pair, time and energy (or some other pairs), is certain, the other wouldn't be certain. |
