If the latest theory of Tom Weiler and Chui Man Ho is right, the Large Hadron Collider – the world's largest atom smasher that started regular operation last year – could be the first machine capable causing matter to travel backwards in time.
"Our theory is a long shot," admitted Weiler, who is a physics professor at Vanderbilt University, "but it doesn't violate any laws of physics or experimental constraints."
According to Weiler and Ho's theory, these singlets should have the ability to jump into an extra, fifth dimension where they can move either forward or backward in time and reappear in the future or past.
It makes sense to me.
As long as they avoid the time machine paradoxes, it should be all gravy!
But I'm not sure how I feel about them messing about with spacetime fabric...
