Unravelling the mystery of multiverse

The multiverse: it’s a mind boggling, jaw dropping, spine tingling idea. Despite the many physicists who considered them an intriguing possibility, for decades multiple universes were considered the stuff of science fiction – there was simply no way of proving they actually existed. Now, Sri Lankan-born cosmologist Dr. Hiranya Peiris and her colleagues at the University College London, Imperial College London and the Perimeter Institute for Theoretical Physics have designed an observational test that can be used to test the multiverse idea, and they’ve begun applying it to data.

multiverse? The evidence that it is actually possible for a multiverse to exist is mostly theoretical says Hiranya explaining that well tested theories like quantum mechanics (“possibly the best tested physical theory there is”), inflation (“the dominant paradigm for the origin of structure, which has passed every observational test so far”) as well as string theory (“an elegant and compelling theory of quantum gravity”) seem to predict their existence. “It is very hard to wriggle out of these predictions,” she wrote in an email to The Sunday Times.
