Could a cold spot found in space be proof of parallel universes sitting side by side ours and show that multiverse theory is indeed correct after all? The debate is still on, but a new study from the UK’s Royal Astronomical Society may be pointing in the direction of parallel universes.
The cold spot in space the scientists are currently studying was first detected in 2004 by NASA’s WMAP satellite and was confirmed in 2013 by ESA’s Planck mission. This spot has confounded astronomers as well as cosmologists, who feel that the odds are extremely slim that the cold spot was created from the birth of the universe. So far, the inflation theory of the origin of our universe doesn’t appear to work mathematically with this mysterious cold spot.
Bringing us ever closer to parallel universes, the Royal Astronomical Society has just ruled out another more mundane explanation for the cold spot in space, which is that it may possibly be nothing more than an optical illusion brought about because there aren’t any intervening galaxies, as the Guardian report. But if this other theory has been debunked, what other theories could potentially be the real reason for this cold spot in space besides parallel universes?
Professor Tom Shanks of Durham University, one of the authors of the new study from the Royal Astronomical Society, states that scientists can’t currently eliminate the theory that this cold spot in space is just an odd fluctuation or anomaly that arose out of the creation of the universe. However, if the standard theory of the Big Bang cannot adequately explain the cold spot, this is when other theories like parallel universes and the multiverse theory would come into play, especially if further evidence corroborates the existence of parallel universes.
“We can’t entirely rule out that the Spot is caused by an unlikely fluctuation explained by the standard theory of the Big Bang. But if that isn’t the answer, then there are more exotic explanations. Perhaps the most exciting of these is that the Cold Spot was caused by a collision between our universe and another bubble universe. If further, more detailed, analysis proves this to be the case. then the Cold Spot might be taken as the first evidence for the multiverse.”
This cold spot in space being studied so fervently by scientists is part of the cosmic microwave background, which is the leftover radiation that exists now because of the Big Bang and the creation of the universe. One hypothesis for its existence, and the one that excites people the most, is that this dark, cold place in space may actually be the result of two universes colliding. If this were, in fact, the case, it would also be the first ever concrete evidence that multiverse theory is correct and that there could conceivably be millions or even billions of hidden universes ensconced near ours.

Because the cosmic microwave background is dispersed over the entirety of the sky, scientists have mapped out the radiation in the universe and found that, for the most part, radiation is equally distributed and is also the same temperature everywhere. This cold spot, however, is the one place in which it is not.
Durham University’s Ruari Mackenzie explained that standard cosmology is still unable to rationally account for this cold spot in the universe, as the Independent report.
“The voids we have detected cannot explain the Cold Spot under standard cosmology. There is the possibility that some non-standard model could be proposed to link the two in the future but our data place powerful constraints on any attempt to do that.”
Professor Tom Shanks believes that astronomers will eventually be able to analyze evidence to see if two universes really may have collided and if parallel universes are the cause of the cold spot lurking in our universe, as the Express reported.
“I remember some scientists suggesting that there could be detectable effects on the galaxy distribution after this ‘cosmic shunt’ of two universes colliding. Basically, colliding universes could leave a slightly anisotropic galaxy distribution in our own universe – a bit like a pile-up on the motorway. So we can look for this to test how seriously to take these ideas.”
With the right tools and adequate time, scientists will one day be able to determine whether parallel universes exist and whether multiverse theory is true, and this cold spot in space may be one key to solving the puzzle.
