There's a hypothesis going around the Vanderbilt University among researchers about the possibilities of the Large Hadron Collider [LHC] being capable of TIME TRAVEL...!
They are theorizing that when the LHC produces a Higgs boson it could also create a Higgs singlet at the same time...(are you scratching your head...? me too) When or if this ever happens it would be possible for particles to travel forwards and backwards in time in the fifth dimension.
Vanderbilt University's professor Tom Weiler explains the good and bad of the whole process:
"Our theory is a long shot, but it doesn't violate any laws of physics or experimental constraints."
"One of the attractive things about this approach to time travel is that it avoids all the big paradoxes," Weiler said. "Because time travel is limited to these special particles, it is not possible for a man to travel back in time and murder one of his parents before he himself is born, for example."
"However, if scientists could control the production of Higgs singlets, they might be able to send messages to the past or future."
