OK, here we go..........
So, the problem is like the time tourist conundrum, if we had the ability of time travel then surely there would be people from the future wandering around right now etc.
So, if that theory is applied, then how can a sub-atomic particle (with i assume, due to the restrictions of science currently has no consciousness etc) travel back in time to 'put a stop to what created it ?' If this were the case, surely it would already have managed to put a stop to it ?? Etc etc, oh sh*t, now i am confusing myself.
Do you get my point ?? I need a cup of tea
