Scientists find ‘evidence’ of another universe before ours
Scientists find evidence of previous universes in the night sky, that is, the remains of black holes from a previous universe.
According to New Scientist, the concept is based on something known as conformal cyclical cosmology (CCC). What it means is that our universe, instead of starting with a single Big Bang, goes through continuous cycles of Big Bangs and compressions.
While the vast majority of the cosmos would be wiped out from one cycle to the next, these scientists say some electromagnetic radiation could survive the recycling process. Their findings have been published on arXiv.
“What we claim we are seeing is the final remnant after a black hole evaporated in the previous aeon,” Oxford University mathematical physicist Roger Penrose, a co-author of the study and co-creator of the theory, told New York. CCC. Scientific.
The evidence comes in the form of “Hawking points,” named after the late Stephen Hawking. He hypothesized that black holes would release Hawking radiation, which Penrose and his colleagues say can travel from one universe to another.
They believe that the Hawking points could arise in the cosmic microwave background, which is the leftover radiation from the Big Bang (CMB). On the CMB map, falconry spots would appear as rings of light known as B-modes.
These aberrational locations in the CMB were previously thought to have been created by gravitational waves or interstellar dust. However, Penrose and his colleagues believe their theory may provide an exciting answer, and the BICEP2 project, which aims to map the CMB, may have already discovered one such Hawking point.
“Although apparently problematic for cosmic inflation, the existence of such anomalous points is an implication of conformal cyclic cosmology (CCC),” the team wrote in their paper.
“Although it has an extremely low emission temperature, at CCC this radiation is highly concentrated by conformal compression from across the black hole’s future, resulting in a unique crossover point into our current aeon.”
The idea of the universe of recycling is not without debate. Most of our data implies that the expansion of the universe is accelerating, and that the cosmos is not dense enough to condense into a single point and expand again, a notion known as the Big Bounce.
