What is the 'universe before the Big Bang' that the 2020 Nobel Prize in Physics talks about?



Roger Penrose , an authority who has made various achievements in space physics, won the 2020 Nobel Prize in Physics for clarifying that 'the formation of black holes supports the general theory of relativity', and Penrose's A person who is also known for devising impossible figures such as the triangle and Penrose stairs . 'There was another universe before the Big Bang, and we can still observe it,' Penrose said.

The Big Bang is seen as the beginning of the universe, but Penrose said that another universe existed before the Big Bang and its traces can still be observed. 'The Big Bang is not the beginning, there is something before the Big Bang. It can be said that it is in our future. The universe in which we are now expands repeatedly, and all mass decays. But my crazy theory is that there is another big bang in the distant future, 'Penrose argues.

Penrose's discovery of traces suggesting that the universe existed before the Big Bang can be best understood in the following article, which summarizes Penrose's 2019 research.

It is a trace of a black hole that disappeared, and the area 'Hawking Point' where strong electromagnetic waves are observed is a trace of the universe that seems to have existed long ago. Penrose mentioned 20 hawking points in the 2019 study, but in the 2020 study, 'certain evidence that at least 6 hawking points are in the cosmic microwave background (CMB). There is. ' Penrose said the theory of Hawking points in CMB the Royal Astronomical Society in the announcement has been, if it is proven the existence of Hawking point, that of the presence of the big bang before the universe is made to be more sure.

As with Penrose's claim, the universe repeatedly expands, eventually contracting and converging to a dimensionless singularity , and then a new big bang may occur, a science that supports ' Big Crunch '. While there are many, some researchers have said that it is 'controversial.'



Penrose, along with

Stephen Hawking , is also known for proving the penrose-hawking theorem , which causes gravitational collapse to reach infinite mass when an object becomes too dense, and all known natural laws disappear. I will. Penrose's and Hawking's papers on the singularity theorem are also considered to be 'the most important contribution since Einstein to the theory of relativity.'

Professor Martin Rees, an astronomer at the University of Cambridge, said of Penrose's Nobel Prize, 'He is surprisingly original and has provided creative insights for over 60 years, as well as Penrose and Hawking. Is the person who has done the most to deepen his knowledge of gravity since Einstein. It is not possible for Hawking to share his honor with Penrose because he was so late in winning the Nobel Prize. I'm really sorry. '



Penrose said he was positive about the timing of the award, saying, 'I know scientists whose research has been ruined because of the early award, so it's good to win the Nobel Prize too early. I don't think. If you're going to win the Nobel Prize in science, it's best to win it when you're old, before you get tired, and when you still have work to do. That's it. '
