Astronomers found first evidence multiverse, a cosmos where there are multiple universes.
A supervoid is unlikely to explain a ‘Cold Spot’ in the cosmic microwave background, according to the results of a new survey, leaving room for exotic explanations like a collision between universes.

The cosmic microwave background (CMB), a relic of the Big Bang, covers the sky. At a temperature of 2.73 degrees above absolute zero (or -270.43 degrees Celsius), the CMB has some anomalies, including the Cold Spot.
The researchers, led by postgraduate student Ruari Mackenzie and Professor Tom Shanks in Durham University’s Centre for Extragalactic Astronomy, publish their results in Monthly Notices of the Royal Astronomical Society.
Ruari Mackenzie, explained:
“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.”
