The multiverse theory has long been a subject of fascination for a huge number of scientists and science enthusiasts. In fact, the concept of a parallel universe has been portrayed in countless science fiction films and novels. In the scientific community, however, the notion that there are other universes existing in the same ecosystem as our own is an exotic one — at least until researchers discovered a mysterious “Cold Spot” in the universe.
Based on Albert Einstein’s theory of relativity, the universe was born out of the Big Bang. This event left a cosmic microwave background across the universe, which comprises trillions of galaxies and spans 92 billion light years in diameter. Experts discovered that this cosmic background is equally distributed and has the same temperature.
For the most part, at least.
Scientists discovered that this cold spot is 0.00015 degrees Celsius cooler and has 20-percent less matter than the rest of the universe.
Of course, the scientific method requires scientists to consider other theories that may better explain the cold spot. One popular theory suggests that it was the result of a supervoid, which suggests that the cold spot was actually a large space comprising very universes.
A new study, however, suggests that might not be the case under the Standard Model. As a result, scientists were compelled to take a closer look at the multiverse theory, and examine further if the cold spot could be our first proof that the multiverse exists, as reported by the Independent.

Researchers from Durham University said in a recent study that the cold spot could be the result of a parallel universe crashing into ours, shoving away galaxies and matter in the process.
They also explained that if the universe is brought about by the Big Bang and is now expanding at an infinite scale, then it follows that parallel universes have been born alongside ours as well.
Have scientists discovered first proof of a #multiverse?

“The voids we have detected cannot explain the Cold Spot under standard cosmology,” said Ruari Mackenzie from Durham University. “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.”
Researchers from Durham University are now considering the most exciting explanation for the cold spot — that it was the result of another universe bumping into our own. It might be our first proof that the multiverse theory is true — that there are billions of other universes, some of them variably identical to our own, existing in the same ecosystem as ours.
“This means we can’t entirely rule out that the Spot is caused by an unlikely fluctuation explained by the standard model,” said Tom Shanks. “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 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.”
The concept of the multiverse theory is as exhilarating as it is strange. Each parallel universe, for one, has another version of reality. And the number of possibilities is limitless, so much so that there might be one out there in which you are the U.S. president tweeting the most infantile tweets imaginable.
Ironically, one of the first architects of the multiverse theory is now one of its most vocal critics, the Guardian reports. Paul Steinhardt of Princeton University helped develop the theory that once the universe is formed it also triggers the birth of other universes ad infinitum.
In 2014, Steinhardt opposed his own theory.
“Our observable universe would be just one possibility out of a continuous spectrum of outcomes. So, we have not explained any feature of the universe by introducing inflation after all. We have just shifted the problem of the original big bang model (how can we explain our simple universe when there is a nearly infinite variety of possibilities that could emerge from the big bang?) to the inflationary model (how can we explain our simple universe when there is a nearly infinite variety of possibilities that could emerge in a multiverse?).”
