A mysterious cold spot in space might be evidence of a parallel universe.
Scientists have long been looking for an explanation for the strange, dark area in the cosmic microwave background – the radiation leftover from the big bang. A range of different explanations have been proposed, but the main one isn’t likely to make sense and it could actually be a parallel universe.
More specifically, the area could be the consequence of a collision between two different universes. It might be the first ever evidence of the theory of the multiverse – that there are billions of other universes, some of them just like our own, lurking outside the one that we can see. “Perhaps the most exciting of these [theories] is that the Cold Spot was caused by a collision between our universe and another bubble universe. If further, more detailed, analysis of CMB data proves this to be the case then the Cold Spot might be taken as the first evidence for the multiverse – and billions of other universes may exist like our own.”
