It’s time for some exciting news from the world of physics and cosmology. A Caltech cosmologist recently announced he was found evidence of parallel universes!
If that’s true and can be confirmed, it means our Universe is just one of many universes co-existing next to each other. The idea that our Universe could be a small component within a vast assemblage of other universes that together make up a “multiverse” has been treated by physicists as intriguing, but so far it has remained in the realm of theory without any experimental tests that could support it.
Due to the difficulties proving the theory many scientists have remain cautious. Some years ago a group of scientists declared they had found evidence of Universe could be part of a soap bubble.
Now, Caltech cosmologist Ranga-Ram Chary thinks he may have found evidence of a parallel universe. In a new study, published in the Astrophysical Journal, Chary suggests cosmic bruising — one universe bumping up against another universe — could explain an anomaly he found in the map of the cosmic microwave background.

Using data from the European Space Agency’s Planck telescope, Chary developed a cosmic microwave background map. When he compared it with a map of the entire night sky, he suddenly found an unexplained blob of bright light.
The cosmic background features bursts of ancient light, revealing the radiation signatures of the universe just a few hundred thousand years after the Big Bang. This ancient light is the result of recombination, when electrons and protons first teamed up to create hydrogen. Because hydrogen gives off a limited range of visible light, astronomers know what colors these ancient blobs should and shouldn’t be.
The blob of note is a color it shouldn’t be. In his new paper on the discovery, Chary argues a multiverse theory could explain the phenomenon.
“Our universe may simply be a region within an eternally inflating super-region,” Chary wrote.
“I would say most versions of inflation in fact lead to eternal inflation, producing a number of pocket universes,” Alan Guth, a researcher at MIT and one of the architects of the inflation theory said.
Ranga-Ram Chary is aware of how difficult it is to prove this complex theory and he knew his ideas would face strong skepticism. “Unusual claims like evidence for alternate universes require a very high burden of proof,” he said.
