U.K. scientist believes that the Big Bang was not the beginning of the universe, but rather a part of a series of "cosmic deaths and rebirths". Roger Penrose, theoretical physicist at the University of Oxford, thinks that circular patters in the universe "pervasive background" may show that the universe was actually formed before the Big Bang. It also suggests that the universe has had multiple cycles of creation in the past.
However, there is controversy over this theory that some scientists do not agree with this idea. The theory of Penrose and another scientist, Vahe Gurzadyan from Yerevan State University, contradicts the theory of inflation. The theory of inflation say that the infant cosmos underwent an enormous growth spurt in its first tiny fraction of a second. Therefore, scientists say that inflation would have erased the patterns that Penrose and Gurzadyan have claimed that they have found. In their paper, Penrose and Gurzadyan suggests that the circles that they found were created by collisions with large black holes that occured in the previous universe. This would then create sphere shaped gravity waves that may have entered this universe.
I was interested in this article since I always thought that there was only one beginning of the universe, and the idea that there could have been more seemed interesting. One question that I have is how were Penrose and Gurzadyan able to detect the gravitational circles in the universe. Also, if there were multiple beginnings of the universe, could another rebirth happen again, and what would cause the death and rebirth of the universe? If these findings are further supported by more evidence, we could be closer to understanding how everything came to be.
