Would, hypothetically speaking from the Big Crunch theory, in fact the arrows of time(psychological,cosmological, and thermodynamical)reverse as the universe starts to contract again? Since entropy increases with time and the thermodynamical arrow of time is the direction of increased or decreased entropy, that would mean that the therm. arrow follows time as it is now, right? As the universe would contract, the entropy would decrease and therefore the therm. arrow would then be in the opposite direction. I wonder about this since the thermodynamical arrow of time corresponds with the other two. Time would then be going backwards from our current reference point and people, if they managed to exist that long, would observe the supposed future before the past. Please elaborate if these ideas are right or wrong.
