Sir Roger Penrose also claims that another universe will exist after this one

Key takeaways

  • Nobel Prize-winning physicist Sir Roger Penrose suggests a universe existed before the Big Bang.
  • He believes that ‘Hawking Points’ in the sky are remnants of this previous universe.
  • These points are thought to be energy emissions from black holes in the earlier cosmos.
  • Penrose’s “conformal cyclic cosmology” theory proposes that our universe will also lead to another universe in the future.
  • The idea remains controversial, with some scientists questioning the existence of Hawking radiation and the theory’s validity.

A Nobel Prize-winning physicist has stated that a previous universe existed before to the Big Bang, and proof for its existence may still be found in black holes.

Sir Roger Penrose made the assertion following his recent award for advancements in Einstein’s general theory of relativity and proof of the existence of black holes.

Sir Roger contends that mysterious regions of electromagnetic radiation in the sky, called as ‘Hawking Points’, represent leftovers of a former cosmos.

It is part of the universe’s “conformal cyclic cosmology” idea, and it is proposed that these spots constitute the ultimate emission of energy known as ‘Hawking radiation’, which black holes transfer from the earlier cosmos.

Black holes are regions of space where matter has collapsed on itself, with such a strong gravitational pull that even light cannot escape.

Such an event might be occurring at the center of our galaxy; Reinhard Genzel and Andrea Ghez, who shared the Nobel Prize with Sir Roger, presented the most persuasive evidence of a supermassive black hole in the Milky Way.

The period for a black hole’s entire evaporation may be greater than the age of our present universe, making detection impossible.

“I claim that there is observation of Hawking radiation. The Big Bang was not the beginning. There was something before the Big Bang and that something is what we will have in our future”, Sir Roger said, according to The Telegraph.

“We have a universe that continues to expand, and all matter decays away, and in this insane hypothesis of mine, that far future becomes the Big Bang of another aeon.

“So our Big Bang began in the distant future of a previous aeon, and there would have been similar black holes evaporating away via Hawking evaporation, resulting in these points in the sky that I call Hawking Points.”

“We’re seeing them. These locations are approximately eight times the diameter of the Moon and are somewhat warmed up areas. At least six of these points are supported by reasonable evidence.

However, many people have criticized the theory, and the reality of this form of radiation from black holes has yet to be proved.

Furthermore, if an infinitely vast universe in one existence must become an endlessly tiny universe in the next, it would be necessary for all particles to lose mass as the cosmos matures, an idea that has also been challenged.

According to conventional cosmology, the universe experienced a short expansion or ‘inflation’ following the Big Bang, which erased abnormalities in its structure.

Sir Roger responded by stating that black holes were likewise disregarded as simply being in mathematics until their actuality was proven.

“People were very sceptical at the time, it took a long time before black holes were accepted… their importance is, I think, only partially appreciated”, he said, as reported by the BBC.
