Even though the parallel universe is just a theory, Ranga-Ram Chary from the California Institute of Technology may change our thinking about this by claiming that he found evidence of a parallel universe to ours.
According to scientists, our universe has formed approx. 13.8 billion years ago.
Hundreds of thousands of years after the Big Bang explosion that suggested the beginning of our Universe, the particles that existed were too hot and too energetic to condense into atoms, but this changed after 300,000 years, the event is called recombination.
Besides recombination, at that time the spread of cosmic radiation or CMB began over the Universe.
Cosmic radiation is widely used in astronomy to look back in time even billions of years ago.
Chary found, as he claims, a "bruise" in cosmic background radiation, or rather a crack, which could indicate a collision with another parallel universe.
If parallel universes exist, scientists say that then it might be normal for different universe bubbles to collide with each other.
However, it is not clear if Chary really noticed such a crack that could firmly support the existence of other universes.
He even says that there is a 30% chance that what he noticed is just background noise or more likely a high concentration of space dust.
The data that the cosmologist investigated was collected by the powerful Planck telescope of the European Space Agency (ESA).
"I suspect that it would be worth looking into alternative possibilities," David Spergel from Princeton University told Joshua Sokol at New Scientist. "The dust properties are more complicated than we have been assuming, and I think that this is a more plausible explanation."
"Joseph Silk of Johns Hopkins University in Baltimore, Maryland, is even more pessimistic, calling claims of an alternate universe 'completely implausible'," adds Sokol. "While he thinks the paper is a good analysis of anomalies in Planck data, Silk also believes something is getting in the way. 'My view is that they are almost certainly due to foregrounds.'"
"Unusual claims like evidence for alternate universes require a very high burden of proof," he writes in his report, published online at arXiv.org. "Searching for these alternate universes is a challenge."
