However, nothing in the laws of physics insists that time must move forward.
Is it possible that there exists a place where time actually moves backwards?
By this explanation, time which runs backwards would still go in accordance with the laws.
Many physicists have settled on entropy, the level of molecular disorder in a system, which constantly increases.
So time in this parallel universe moves backwards from our perspective.
However, anyone in the parallel universe would see our universes time as moving backwards.
Eventually, they said, arrows of time that flowed in a specific direction spontaneously developed.
This means that the direction of the individual arrows has no importance, because the cloud will always expand.
