The interesting part to ponder is time existing or not existing the only two choices. This one usually catches most people out who will swear that it is that black and white. So lets give you a couple of examples in shadows and rainbows.
If light exists, then shadows and rainbows exist.
The existence, or otherwise, of time is a question that leads to speculation and, possibly, metaphysics. It may not even be a question for science. Science needs time in order to make calculations, so “shut up and calculate” is undoubtedly the most practical approach.
I raised this question because I overheard someone mention a watch that was “accurate to 1 second in 1,000 years”, and I thought: what does that actually mean?
I think there is a possible third option in the existence/non-existence of time debate, but I’m trying to keep off infinity/eternity. We have enough repetitive crackpottery already.
