Multiverse is closer than you think

A curious chilly area of space may have been created when a parallel universe crashed into our own, scientists have suggested - the first evidence that we may be part of a multiverse.

In 2015 astrophysicists discovered a strange barren area of the universe which was much colder than the rest of space.

The "cold spot", which is 1.8billion light years across, is the largest known structure ever discovered, yet appeared to contain 20% less matter than it should, and has baffled scientists since it was recorded.

But now experts at Durham University have come up with a solution which is not only out of this world, but out of this universe.

They believe that a parallel universe crashed into ours, much like in a traffic accident when cars pile up on the motorway.

The impact was so extreme that it pushed energy out of a huge area of space, creating the cold spot.

Scientists now believe that if our universe "ballooned up" after the Big Bang, then trillions of others could also have formed in the same way, creating other universes.

Tom Shanks, of Durham University's Centre for Extragalactic Astronomy, said: "One explanation for the cold spot is that it might be the remnant of the collision of our universe and one of trillions of others.

"If more detailed analysis 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 cold spot is about 3billion light years away from Earth, a relatively short distance in the cosmic scheme of things.

The whole universe is covered in cosmic microwave background, but while the temperature of most of the background is 2.73C above absolute zero, the cold spot is about 0.00015C colder than its surroundings.
