A cosmologist's findings prove that having a parallel universe may indeed be possible.
The concept of the existence of multiple parallel universes is not new, building on the idea of cosmic inflation. But while the theory has grown more popular over the years, there has been no solid evidence proving it true.
However, when cosmologist Ranga Ram-Chary from Caltech found a strange blob of light in a cosmic microwave background made by the data obtained by the European Space Agency, the possibility of it being a cause of multiverse existence did not escape him. The strange light appeared when Chary compared the background map to the night sky.
"It could also possibly be due to the collision of our Universe with an alternate Universe whose baryon to photon ratio is a factor of around 65 larger than ours," Chary wrote in his study, Spectral Variations of the Sky: Constraints on Alternate Universes.
It sounds like something straight out of a science fiction novel, but what makes some scientists so sure of the validity of the multiverse theory?
Surprisingly, there are many supportive theories.
Scientists believe that the space-time continuum is most probably flat and stretched to infinity, and if one looks at the distant space-time long enough, the existence of an infinite number of alternate universes can be found because there are only a finite number of ways particles can rearrange themselves in space and time.
Another theory is that parallel universes are most likely due to the possibility that many dimensions to this world exist other than the ones currently known.
"[It could be possible that] our universe is one of potentially numerous 'slabs' floating in a higher-dimensional space, much like a slice of bread within a grander cosmic loaf," said physicist Brian Greene of Columbia University in his book, "The Hidden Reality."
Despite these theories, there is still no solid proof on the existence of such multiple or parallel universes. However, its supporters like Chary are still working on finding more concrete evidence in proving that it is indeed possible.
