Its been well know for a while now that observation ( bouncing light of a particle ) somehow gives particles wave like properties or in other ways alter the nature of the particles in question.
See link if you got no clue what i'm talking about
Recently i saw a variation of the experiment where scientists was able to delay their decision about observation untill after the particles left the slits, but before they hit the wall behind them.
The electron gun fired single electrons. The electrons acted like waves after passing through the slits. But at the exact moment of observation the waves suddenly turn back into particles, and apparently always was particles. So its as if the electrons went back in time to before they passed through the slits and then decided to go through one or the other comming out like single electrons instead of the waves you would expect. All because you observed it.
Somehow we can influence particles in a way that allows them to travel through time.
Its also worth mentioning that because of their wave like properties its impossible to determine the exact location of these particles. Whats even more interesting is that if we try to box in a particle it will always generate enough energy to break out of the box before its position and speed have been determined. The uncertainty principle suggests that nature will not allow its fundamental elements to be boxed in. Its as if something is trying to prevent us from getting access to specific knowledge.
I don't know.. I guess i'm asking for theories from random strangers on the intrawebz.
