i was wondering why time only moves forward when all other dimensions can move either way but time seems to only move forward. i was thinking with enough knowledge of how time moves and enough energy we could possible reverse the flow of time.
i was also wondering if the entire universe was one big paradox were the universe plays out to a point and then somehow moves backwards and then started over moving forward.
these are just ideas that hit me so they may sound a bit dumb but i think they may be plausible.
