Some Russian mathematicians claim that when the atom-smashing machine at the European Particle Physics Centre near Geneva opens for business at the end of April, one of the results of wee particles being smashed together at insane speeds could be a rip in the fabric of time itself, allowing for tiny particles to jump in time. If we figure out how to hold open said rip, maybe, just maybe, we could go back or forward in time.
