Sir Roger Penrose thinks that there have been many Big Bangs and that there will be more in the future. Sir Roger Penrose, a mathematician and physicist from the University of Oxford who recently shared this year’s Nobel Prize in physics, says that our universe has been through many Big Bangs and will go through another one soon.

Penrose won the Nobel Prize in Physics for developing mathematical methods that proved and expanded Albert Einstein’s general theory of relativity. He also won the prize for his discoveries about black holes, which showed how objects that become too dense collapse under the force of gravity into singularities, or points with infinite mass.
As soon as he found out he had won the Prize, Penrose said he still believed in “a crazy idea of mine” that the universe will keep expanding until all matter breaks down. After that, there will be a second Big Bang, which will make a new universe.
“The Big Bang was not the beginning,” Penrose said in an interview with The Telegraph. “There was something before the Big Bang and that something is what we will have in our future. “What proof does the physicist have for this theory he dubbed “conformal cyclic cosmology” (CCC) that goes against the current Big Bang dogma?
He said he had found six “warm” spots in the sky, which he called “Hawking Points,” that were each about eight times the size of the Moon. Professor Stephen Hawking, for whom they are named, came up with the idea that black holes “leak” radiation and eventually disappear. Since this could take longer than the age of the universe we live in (13.77 billion years), it is very unlikely that we will find such holes.
Penrose, who worked with Hawking and is now 89 years old, thinks that we can see “dead” black holes from other universes or “aeons.” If this is true, it would prove that Hawking’s ideas are right.
The physicist’s research from 2020, which was published in the Monthly Notices of the Royal Astronomical Society, shows that there are “anomalous circular regions” with higher temperatures in the CMB. Using information from the Planck 70 GHz satellite and up to 10,000 simulations, the spots were found. In his 2018 paper, Penrose found radiation hot spots in the CMB that could be caused by black holes that are fading away.
In 2010, Penrose and Vahe Gurzadyan of Armenia’s Yerevan Physics Institute wrote an article about how the CMB’s uniform temperature rings support cyclic cosmology. At the time, scientists thought that the rings were made by gravitational waves from black holes that merged in a universe before ours.
Cosmologists don’t all agree on these ideas. Some say it would be hard to go from an infinitely large universe in one aeon to a very small one in the next. This would mean that all particles lose mass as the universe ages.
Here you can find Penrose’s most recent paper, which is called “Apparent evidence for Hawking points in the CMB Sky.”
