Ranga-Ram Chary, U.S. Planck Data Center's project manager in California, discovered a "mysterious glow" by mapping the Cosmic Microwave Background, which is thought to be remains for the big bang.
While a glow usually means nothing, the spots of light were 4,500 times brighter than they should have been.
Ordinarily, Chary would have found nothing "except noise." But the spots of light were 4,500 times brighter than they should have been.
However, Jens Chluba, from the University of Cambridge, told the New Scientist: "This signal is one of the fingerprints of our own universe. Other universes should leave a different mark."
In Chary's paper, Spectral Variations of the Sky: Constraints on Alternate Universes, he explained that while there is a 30 percent chance the fluctuations are nothing unusual, there is also the possibility they provide evidence of a multiverse.
"It could also possibly be due to the collision of our Universe with an alternate Universe whose baryon to photon ratio is a factor of around 65 larger than ours," he wrote.
Overall, while most scientists recognize that Chary may have made a huge discovery, they believe the results are highly inconclusive.
