Turns out it wasn’t 88mph after all. A team at the Massachusetts Institute of Technology has completed a successful experiment with quantum time travel.
Seth Lloyd and his collaborators “have identified a new approach to the problem that opens up the strange world of time travel to experiments,” according to a report in New Scientist magazine.
Even more fascinating, the MiT team sent a photon back to “kill” itself.
The magazine says, ‘When this experiment is done, something interesting happens: every single time the time travel works, the gun fails to go off. And when time travel fails, the gun works. To put this in the language of the grandfather paradox, as long as there is some chance of your gun misfiring and the assassination failing, time travel may work. “You can point the gun but you can’t pull the trigger,” says Lloyd.’
