you can go forward in time, but not back in time.. They've proven it, but I'd hafta dig up the article.. They have only been able to go forward in time a very small amount (a second or two or three) so the theory is correct - they just need to, ya know, get better at it.. However, I've read going back in time is impossible - or at least hasn't been figured out yet..
