Time is a human construct designed for measuring and scheduling and has no meaning whatsoever outside of human endeavor.

The universe and the infinite space the universe resides in exist at “now” : an important tenet of ‘relativity’. No past. No future. Now. Past, future, time… these are constructs of sentient organisms. The universal “don’t believe everything you think” immediately comes to mind.

We exist in space. Space is infinite - it has no boundaries or edges, has always existed and will always exist. We also exist in this (“our”) universe - which is infinite, did have a start date, and will come to an end someday. Not soon. Hopefully.

Space is also infinite “bigger” and “smaller”. But let’s save that for another time.

(but does cesium REALLY vibrate the same in different parts of space? h’mm?)
