[T]he idea that we live in a “multiverse” made up of an infinite number of parallel universes has long been considered a scientific possibility – although it is still a matter of vigorous debate among physicists. The race is now on to find a way to test the theory, including searching the sky for signs of collisions with other universes.

If String Hypothesis is correct, it is possible that the LHC at full power might actually detect it by creating mini black holes. This would be incredible.
Note that what this particular article is not discussing is the possibility of Kaluza-Klein particles which would, if detected, be able to tell us not only about the existence of extra dimensions, but about the shapes of the compactified dimensions. But, that will have to wait for another article.
