Time was, about time, time to do… Time is everywhere and nowhere. Have you ever lost track of time? Ever felt uncomfortable because you didn’t know what time it was? Felt that time had stopped?
See, time is fluid. For instance, if a man takes a trip in space and comes back twenty years later, his little children will be old men and women. This is mentioned frequently in science fiction stories. It’s a reason for the man in space to stay where he is and not return.
Time is a construct created by man to structure his days and years. Because we have a moon, they also had months. Before clocks were invented, people used the location of the sun to define their day. High noon meant dinner, sun dropping behind the world meant bed time. Until they harnessed fire.
Out in deep space, beyond the stars, there is no time as we know it. There is motion, however, as stars move along their orbits around the center of the galaxy, and the galaxy itself moves through space.
In our modern, structured life we do need to be aware of when we need to be places or do things, so we have clocks and timepieces to tell us when we need to do these things.
