“Time, instead, is a by-product of matter in motion.”
Well, that’s one of the old ways of thinking about time, that it was just kind of an after effect of measuring motion in matter, and noticing that motions could be cyclical so we could derive units of time from those cycles.
But Einstein showed that in fact almost the opposite is true. For matter experiences time only because our motion in space is so small. Energy, on the other hand, which can move through space at the speed of light, experiences no time at all. So it may be that time is actually the byproduct of a deficiency of motion, and not motion itself.
Interesting. But I will stay with my long-held observation.
Time is also affected by gravity. This was proven by an experiment where two atomic clocks were synchronized exactly the same, one was put aboard a satellite and orbited around the Earth.
The orbiting clock, over a period of time, was actually ahead of the Earth-bound clock.
I’m relating this from memory, and it’s been a lot of years since I read about this, so feel free to correct me if needed.
