Does the future affect the past?
I understand that if time were something like a linear line, it is by no means constricted to travelling any one direction. In fact, I believe the idea of time itself travelling is silly. Time doesn't flow forwards, it just is. Humans are ass-deep in an inflatable tube on the river of life. You can't paddle against the current, and it only flows one way. Such as we, the drunk, sun-burning participants. Maybe I'll change my mind about this a little while ago.
