New submitter LCooke writes: A international research team led by the University of Durham thinks a mysterious cold spot in the universe could offer evidence of a parallel universe. The cold spot could have resulted after our universe collided with another. Physicist Tom Shanks said, [...] "the cold spot might be taken as the first evidence for the multiverse -- and billions of other universes may exist like our own." From the report via Inhabitat: "NASA first discovered the baffling cold spot in 2004. The cold spot is 1.8 billion light years across and, as you may have guessed, colder than what surrounds it in the universe. Scientists thought perhaps it was colder because it had 10,000 less galaxies than other regions of similar size. They even thought perhaps the cold spot was just a trick of the light. But now an international team of researchers think perhaps the cold spot could actually offer evidence for the concept of a multiverse. The Guardian explains an infinite number of universes make up a multiverse; each having its own reality different from ours. These scientists say they've ruled out the last-ditch optical illusion idea. Instead, they think our universe may have collided with another in what News.com.au described as something like a car crash; the impact could have pushed energy away from an area of space to result in the cold spot." The study has been published in the journal Monthly Notices of the Royal Astronomical Society.
