A scientist may have found evidence that could prove the notion that multiple universes do exist.
Astrophysicist Ranga-Ram Chary of California's U.S. Planck Data Center made the discovery after studying the aftermath of the Big Bang, Pulse Headlines reported.
As detailed in a new study, Chary discovered a mysterious glow that can be traced back to the Big Bang event that happened hundred thousands of years ago. This caught his attention because even though the cosmic event occurred a very long time ago, the lights were 4,500 times brighter than expected.
This led Chary to believe that the lights may have been caused by universes colliding. They could also be matter leaking from another universe.
This notion supports the cosmic inflation theory which suggests that right after the Big Bang, the universe began to expand, which could lead to the development of a multiverse.
"The properties of our observable universe have recently been characterized in unprecedented detail through analysis of the cosmic microwave background fluctuations, a relic of the hot Big Bang," Chary wrote in his study.
"The fine tuning of parameters in the early universe required to reproduce our present day universe suggests that our universe may simply be a region within an eternally inflating super-region," he added.
Chary then explained that based on this notion, the other universes will have a different set of parameters that are unlike those governing the universe we live in.
Other scientists, however, remain skeptic regarding the notion of a multiverse. For them, the mysterious lights observed by Chary could be caused by other factors.
"I suspect that it would be worth looking into alternative possibilities," David Spergel of Princeton University said according to UPI. "The dust properties are more complicated than we have been assuming, and I think that this is a more plausible explanation."
The head of Williams College's astronomy department, Jay Pasachoff, also noted that the spot of lights left over by the Big Bang cannot be considered as solid proof behind the existence of a multiverse.
"The supposed observations of a giant void and an apparently cold spot in the cosmic background radiation have so many types of potential explanations," he said according to the Huffington Post.
Although Chary believes that he has discovered evidence pointing to parallel universes, he admitted that additional studies need to be conducted to further support his claims.
Chary's study was published on September 30 in the Astrophysical Journal.
