How is the universe bounded by time? Perhaps it's bounded by our perception of time, but that doesn't mean time cannot be infinite.

- JoeAltmaier 11y agoBecause things can only happen until entropy heat-death. Then there's not enough energy to do anything. Stuff stops happening. And that's in, what, 20 trillion years? So bounded. { edited: trillion } Ha! 10^30 years by some estimates. So, a thousand billion billion billion years. Anyway, bounded.
- lomnakkus 11y agoI believe heat death is something like on the order of trillions of years. ... but there are also built-in assumptions in that calculation. For example that certain constants will remain constant. EDIT: Typo
