A cosmologist claims that he has discovered an alternate universe. The surprising revelation has been made by Ranga-Ram Chary, researcher at the European Space Agency’s Planck Space Telescope data center at the California Institute of Technology.
The findings, collected under the title “Spectral Variations of the Sky: Constraints of Alternate Universes”, were published in the Astrophysical Journal.
The researcher had been analyzing Cosmic Microwave Background (CMB), which represents the thermal radiation which has remained following the Big Bang.
When the universe was formed, its temperatures were exceedingly high, but as it expanded, it gradually cooled, but there is still heat left over from those times. As electrons and protons recombined, they created hydrogen, which sends off light, but only to a limited extent.
As Chary was mapping CMB, he was expecting to find nothing out of the ordinary, but instead he identified a “mysterious glow” in the sky, which seems to come from those early beginnings of the cosmos, a few hundred thousands years following the Big Bang.
The unusual spots of brightness were in fact 4,500 more luminous than they should’ve been if they had been part of our own universe. The expert now speculates that this is because they actually emanate from another world, whose baryon to photon ratio is around 65 higher than our own.
Basically, cosmic bruising, which occurs when two universes come into contact and collide, seems like the most viable explanation for the anomaly detected in CMB.
“Our universe may simply be a region within an eternally inflating super-region”, explained Chary in his scientific paper.
As supporters of the multiverse theory believe, while the early universe was expanding in a process of chaotic inflation, some pockets of energy developed more rapidly than others.
This has led to the creation of several parallel or alternate universes, according to Alan Guth, researcher at Massachusetts Institute of Technology. These worlds, situated beyond our observable universe, are governed by other physical constants, due to spontaneous symmetry breaking.
This point of view isn’t however supported by other cosmologists and astrophysicists, who dismiss such claims as ludicrous, since there is no way of supporting them through empirical evidence.
Other scientists such as David Spergel, theoretical astrophysicist at Princeton University, believe that foreground dust is a more likely source of disruption, which could account for unusual glow detected in the sky.
Meanwhile, Chary has declared that he would be conducting further studies, in order to test his hypothesis further, and hopefully prove its validity.
As he estimated, there is a likelihood of 30% that the unexpected glow can be explained otherwise, and now his goal is to investigate this possibility.
