An astrophysicist says he may have found evidence of alternate or parallel universes by looking back in time to just after the Big Bang more than 13 billion years ago, reports USA Today.

According to various sources, while mapping the so-called "cosmic microwave background," which is the light left over from the early universe, scientist Ranga-Ram Chary found what he called a mysterious glow, the International Business Times reported.

Chary, a researcher at the European Space Agency's Planck Space Telescope data center at CalTech, said the glow could be due to matter from a neighboring universe "leaking" into ours, according to New Scientist magazine.

"Our universe may simply be a region within an eternally inflating super-region," scientist Chary wrote in a recent study in the Astrophysical Journal.

"Many other regions beyond our observable universe would exist with each such region governed by a different set of physical parameters than the ones we have measured for our universe," Chary wrote in the study.

While the findings sound promising and have already gained the attention of other astronomers, as Russia Today (RT) reported, it could be quite complicated to verify, since the Planck telescope provides limited data for further study.

"Unusual claims like evidence for alternate universes require a very high burden of proof," Chary noted in the study.
