Physics Nobel Laureate Sir Roger Penrose has said that before the Big Bang created the universe as humans know now, there was another universe and cited black holes as the proof of its existence. The 2020 Nobel Prize in Physics has been awarded to Roger Penrose, Reinhard Genzel and Andrea Ghez for their discoveries about the black hole earlier this week. Penrose got the award for a paper that used Albert Einstein’s Theory of Relativity to prove the existence of black holes and its formation.
According to the Nobel winner, there is evidence of ‘unexplained spots’ of electromagnetic radiation spread across the sky and are of the “size of a Full Moon” and has called them ‘Hawking Points’. Penrose has also said that these spots prove the ‘conformal cyclic cosmology’ theory of the universe that suggests that Big Bang only marks the end of one universe and beginning of another, also known as ‘aeon’.
Even though he confessed that the theory is controversial, the Nobel laureate noted that the idea black holes absorb light was once questionable but is now accepted in science. Under Penrose’s theory, Hawking Points resemble the final expulsion of energy or Hawking radiation which is transferred by black holes that existed in the previous universe.
