Nobel Physics Prize winner Sir Roger Penrose claims other universes existed before the big bang


According to, the big bang of the universe may not have been the only big bang to have ever occurred. 

Sir Roger Penrose, the person who suggested this theory, is a mathematician and physicist at Oxford University. Penrose is credited for the discovery that Einstein’s General Theory of Relativity leads to the formation of black holes. He also won the Nobel Prize for his work in the field of black holes last week, and believes that there were other universes before our big bang, and there will be others after as well. 

In Penrose’s expectation, our universe will continuously expand until all matter decays, and then a new universe will begin and take its place. His idea is backed up by what he calls “Hawking Points.” When a black hole is formed, it slowly fades away due to Hawking Radiation. This can take an extremely long amount of time depending on the size of the black hole. It is theorized that some take longer to evaporate than the age of our universe itself, which is approximated to be about 13.8 billion years. Penrose claims that these Hawking Points are the final expulsion of energy from the blackholes of the previous universe. Astronomers have detected 6 of these mysterious Hawking Points, which are about 8 times the diameter of the moon and are slightly warmed up regions.

However, there are still many who believe that Penrose’s idea of Hawking Points is too far-fetched to call a reality just yet. Astrophysicist Ethan Siegel is one of these skeptics. Siegel wrote in Forbes, “Like many before him, he [Penrose] appears to have fallen so in love with his own ideas that he no longer looks to reality to responsibly test them. Yet these tests exist, the critical data is publicly available, and Penrose is not just wrong, it’s trivially easy to demonstrate that the features he claims should be present in the universe do not exist.”
