As far as I know all physical laws are time reversible, but in practise the odds of things organising into a less random (or any particular) state as time goes on becomes vanishingly small for anything outside the quantum domain. Entropy increases.
Lots of people are eagerly making up theories, but I doubt many are saying time travel is a possibly, blithely throwing another king-pin of physics, causality, by the wayside. Baby/bathwater.
Perhaps space-time is space-time-mass/energy; 5 vectors instead of 4 or something, or perhaps CERN goofed.
