I've read somewhere that a single photon is traveling backward and forward in time and that this is supposed to be every photon that exists? 1) Did I read that wrong? 2) Is this part of current science lore? 3) Is it just a proposed idea? May I just let you know why I am asking too. (Curiosity is a terrible beast; especially when you are only an outside observer). I was wondering, if it were so, how we would not be awash in photons filling every conceivable place. I don't want to ask to try be a hijacker or anything so I thought I should explain why I was asking.
