Some have suggested that our four-dimensional spacetime might be a sort of “membrane” moving through a higher-dimensional spacetime and that it is possible that it could move in such a way that time for us would simply stop. There would be no way to see the end of time coming, but one prediction of the theory is that space would expand, pushing the galaxies apart – which is exactly what we observe.
As a side note, I have also heard that if the accelerating expansion of the universe continues forever, that it will eventually pull atoms apart and leave fundamental particles stranded with no way to interact with others as space expands faster than light. Since fundamental particles by definition have no internal mechanisms that could represent a changed state over time, time would be meaningless.
After reading about this theory I had a thought: If it is possible for time to abruptly end in the middle of things, is it also possible for it to abruptly begin in the middle of things? Why not? Could it be that the big bang never happened and the universe started up in its fully formed state? Could it be that humans never evolved but instead descended from a pair named Adam and Eve who had no parents and no childhood?
Obviously, this proves nothing. It’s just an interesting possibility that arises when you start playing around with time. What do you think?
