If the universe reaches a final state at one point, isn’t the implication that this is where all process that defines time ends. If so, how can one speak of things happening “after” that point?
- octachron 7y agoThe final state is a kind of thermal death where thermodynamics say that nothing happens anymore. However, thermodynamics is only an effective theory. It is false on tremendously large time scale: after a very very very large time a random fluctuation can bring down the universe entropy to pre-death level and restart a new non-boring universe (for a very short duration compared to the time spent in the thermal death).
- CuriousSkeptic 7y agoTo clarify. I wasn’t arguing against there being a possibility of an “after” with new universes from nothing. I was curious about what constitutes “a very very very large time” in a universe without clocks
