First Evidence Of Parallel Universes

12 June, 2013 First version of this article was originally published on 6 April, 2012 MessageToEagle.com - The idea that our Universe could be a small component within a vast assemblage of other universes that together make up a "multiverse" has been treated by physicists as intriguing, but so far it has remained in the realm of theory without any experimental tests that could support it. That might change now when a team of scientists has found evidence that other universes, as well as our own actually lie within "bubbles" of space and time. "It would be a pretty amazing thing to show that we have actually made physical contact in another universe," George Efstathiou University of Cambridge said. The theory that invokes these bubble universes is a theory formally called "eternal inflation". According to this theory, such universes are popping into and out of existence and colliding all the time, with the space between them rapidly expanding, meaning that they are forever out of reach of one another. Of course, due to the difficulties proving the theory many scientists have remain cautious. With so many scientists having their hands in these tests and theories, the end game could be plenty of groundbreaking results with universal implications for years to come. I'd heard about this 'multiverse' for years and years, and I never took it seriously because I thought it's not testable," Dr Hiranya Peiris, a cosmologist at University College London. "I was just amazed by the idea that you can test for all these other universes out there - it's just mind-blowing." Dr. Peiris and her colleagues have now worked out that when these universes are created adjacent to our own, they may leave a characteristic pattern in the cosmic microwave background (CMB) - the faint glow left from our Universe's formation.
