The topic of time travel is often debated and more than ever with new theories regarding E=mc2 and the beginnings of our universe.  So what would happen if we time traveled backwards?  This physicist sure proposes an interesting scenario given such a phemomena:

It’s a common trope in science-fiction novels: Astronauts travel back in time by zooming through space at speeds faster than light (usually getting into trouble in the process).

Most physicists think that scenario is impossible.

But let’s suspend disbelief for a second. If it time travel like this were possible, how exactly would it work?

It turns out that objects traveling faster than the speed of light could go back in time — but in the process, a pair of phantom doubles of the speedy object would pop out of thin air, and one would then go backwards and be annihilated with another, according to one hypothesis, which Robert Nemiroff, a physicist at Michigan Technological University in Houghton, Michigan, described in a paper published in May in the preprint journal arXiv.
