I thought at first you asked if physics can be used to see into the past or future, then I realized I'm an idiot.
As for psychics and physics telling and seeing the future in not possible. There are some theories that you may be able to see the future in OTHER parallel dimensions that are branched off from our own, but that is still not very usefull to us.
As for the past, well you get into the whole relative speed of time where you could slow down your own clock where everyone else is moving at a "normal" speed, and you would sort of arrive in the future, but moving back is not possible so again it wouldn't have any consequeces. It would basically be like being on a long journey and after you return everyone has aged incredably fast. That was you could travel quicker through time, not really travel to the future.
If you are into this stuff read "The Fabric of the Cosmos" pretty down to earth explainations, but also goes into the mathamatics in the back of the book if you are into that sort of thing.
