While the concept of multiple parallel universes has intrigued writers and astronomers for years, some of its scientific basis may finally be coming to life. Ranga-Ram Chary, project manager of the U.S. Planck Data Center in California, has discovered what he calls a “mysterious glow” while mapping the Cosmic Microwave Background. It was explained as the light left over from thousands of years after the Big Bang.

Chary said that usually, nothing but noise is observed. However, his recent observations of light spots that were 4,500 times brighter than normal prompted him to submit a paper, titled “Spectral Variations of the Sky: Constraints on Alternate Universes.” He concluded the possibility of another universe colliding or “leaking” into Earth, reports The Huffington Post.

Chary’s findings can potentially validate the hypothesis that “our Universe may simply be a region within an eternally inflating super-region.” “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.

This discovery may provide further direction to cosmologists searching for multiple universes. So far, the “multiverse” has largely remained an object of scientific speculation. Chary’s findings can also strengthen the theory that cosmic inflation, an extension of the Big Bang theory and the notion that the universe expanded immediately after the Big Bang, created a multiverse. However, Chary cautioned that such a claim would “require a very high burden of proof.”

Unsurprisingly, the discovery has been met with its share of skepticism.

Alexander Vlenkin, director of Tuft University’s Institute of Cosmology, said it’s difficult to see how "this signal can be explained by a collision with another bubble universe,” reports The Huffington Post. “Any collisions must have been more like little nudges, but a collision that would greatly enhance the density of protons seems to require a much more violent encounter,” he noted.
