The first test is the presence of the Multiverse

The theory that our universe is inside the bubble that surrounds many alternative universes within their own bubbles, forming a multiverse, will be first tested experimentally by physicists.

Two studies published in the journal Physical Review Letters and Physical Review D, first highlight the question of whether, on what grounds can detect the existence of other universes. Physicists study the cosmic background radiation - relic heat radiation left over from the Big Bang, which may contain evidence of collisions with other universes. Many modern theories of fundamental physics predict that our universe is contained in a bubble. In addition to our bladder, Multiverse should contain other, with each of these bubbles may be universe. In other universes, fundamental constants, and even the laws of nature can be very different from our usual.

The research team has created a number of models of how the sky would look like, in the presence and absence of cosmic collisions, and on that basis has created an innovative algorithm for the analysis of information about the background radiation from the spacecraft NASA’s WMAP (Wilkinson Microwave Anisotropy Probe).

Stephen Feeney, PhD, of University College London, who created this powerful computer algorithm to search for evidence of collisions between "bubble universes", which is co-authored article, said: "This study will test a truly staggering theory that we exist in a vast multiverse in which the universe is continuously appear and disappear. " One of the problems with which a scientist, lies in the fact that people are very fond of the whole array of information available to notice them only suitable for passages that might be just a coincidence. However, the algorithm developed is not so easy to fool, because he laid down very strict rules that there is an analysis of information.

The authors explained that the first results are not conclusive on whether there is a multiverse. WMAP is not the only source of information. Now comes the new information from the satellite of the European Space Agency, which will help in the study.
