A teasing sight of a parallel universe hitting against our own has been discovered by astronomers. Astronomers say they have seen clues in signals from the farthest reaches of cosmos that propose the fabric of our universe is being disturbed by another quite diverse universe. The study can provide one of the first pieces of evidence of the multi-verse theory, which says there are several alternate universes. Dr Ranga-Ram Chary, a scientist at the California Institute of Technology in Pasadena, studied data from the cosmic microwave background assembled by the European Space Agency's Planck Space Telescope. Inside this glow left over from the seconds after the Big Bang, he revealed a number of spots where the microwave light is far brighter than it really should be.

These, as he claims, may be signs triggered by the contact between our universe and another one a few hundred thousand years after the Big Bang about 13.8 billion years ago. According to New Scientist, which first informed the Dr Chary's investigation, this is alike to two bubbles bouncing into each other. These so-called 'bubble universes', which are growing inside the multiverse, bumped into each other as they expanded after the Big Bang, leaving an sign on each other's external surface. In a research paper issued on the open source site arxiv.org and he has submitted to the Astrophysical Journal, Dr Chary says the indications he has seen propose this another universe may be very different from our own.

According to him it might have a ratio of subatomic particles called baryons and photons that is nearly ten times greater than what we see in our own universe. Which means the physics in this parallel universe could be quite diverse from our own.
In his research paper, Dr Chary said: “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.
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.”
To make his deductions, Dr Chary used models of the cosmic microwave background and subtracted it from Planck's images of the whole sky.
He then discarded signals from the stars, gas and dust. With all these uninvolved, all that should have been noticeable in the images was noise.
However, Dr Chary reports that instead of that he found dispersed patches that appear 4,500 times brighter than they should. They are believed to come from an age in the universe's evolution called as recombination, when electrons and protons first united to generate hydrogen.
