Can Cosmic Microwave Background Reveal Parallel Universes?
Parallel universes have always fascinated scientists but the evidence remained elusive. Now one physicist claims to have found a hint for multiverse in the cosmic microwave background (CMB).
According to UPI, Caltech cosmologist Ranga-Ram Chary spotted a blob of bright light on a map of CMB which are remnants of radiation from the Big Bang. According to Chary, the blob of light, unusual in color and intensity, could be a result of another universe colliding with ours. He further suggested that following the Big Bang, pockets universes developed within an ever-inflating eternal space.
"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 wrote in a research published 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. Collision between these regions, if they occur, should leave signatures of anisotropy in the cosmic microwave background but have not yet been seen."
The unusual spot of light seen on the CMB map was 4,500 brighter than what can be expected, The Huffington Post reported.
The paper's author wrote that there is a 30 percent chance that the light may not be anything unusual while other scientists said it there are probable explanations other than multiverse to the observations.
