Time Travel

A 'possible' way to travel back in time is by traveling around a black hole. Black holes drag space and time around with it. So if you could travel towards the region where time is being dragged and travel around it then come back out of the region you could actually return before you came in. madness! But to do this would be extremely hard. You would first need to find a black hole and then also have a vessel of some sort that would be powerful enough to out run the pull of the black hole which is so powerful it could pull in a star.....a long shot, but possible.
