Physicists found what could have been a universe that existed before. Just like the current universe, the old ones had black holes, too.
The researchers reported that Cosmic Microwave Background Radiation, or CMB, which is the same thing that generates white noise on many television, is proof of the remains of the black holes.
The team of researchers includes mathematician from New York Maritime College Daniel An, theoretical physicist from University of Warsaw Krzysztof Meissner, and mathematical physicist from Oxford University Roger Penrose. The study was published in arXiv on Aug. 6.
According to the researchers, they have evidence that can prove the remnants of a black hole existed long before the current universe. Instead of visible light, the black holes leave CMB behind.
The theory is called as Conformal Cyclic Cosmology and suggests that universes develop, expand, then die in succession. After, the black holes leave remnants on the following universe.
"A black hole is a region in space where the pulling force of gravity is so strong that light is not able to escape. The strong gravity occurs because matter has been pressed into a tiny space. This compression can take place at the end of a star's life. Some black holes are a result of dying stars," noted NASA.
"If the universe goes on and on and the black holes gobble up everything, at a certain point, we're only going to have black holes," Penrose told Live Science.
Stephen Hawking's theory implies that radiation is left when a black hole dissolves itself and the said mark can still remain even after the universe's death. If scientists can find the mark, they would have significant reason to believe that CCC is accurate.
Penrose reported that the team has finally found evidence to prove CCC. The team ran a version of analysis which resembles varying patches of the sky while they went through parts of it that did not interfere too much with CMB.
Hawking's theory states that black holes significantly lose its energy and mass over time due to gravitons and photons, which are massless particles. This suggests that black holes shrink over time.
According to Einstein's theory of relativity, objects which contain mass move through time slower as it advances near the speed of light, and distances skew from its perspective. Photons and Gravitons are not subject to the same laws of physics because they are massless.
An added that over a significant amount of time, the black holes would entirely crumble, leaving the universe with massless photons and gravitons. This is why a universe that is filled with photons and gravitons will not have a sense of time and space.
