Among the many theories explaining the life cycle of our Universe, “Conformal cyclic cosmology” is of particular interest. Its author is the famous physicist Roger Penrose, standing in the same row with such personalities as, for example, Stephen Hawking.
The theory tells us that our world exists in a continuous cycle of birth and death: that is, our Universe had descendants, and after its death a new Universe will appear in its place. How will the end of our universe happen?
The scientist believes that in the distant future all particles of our Universe, having a mass, will be gradually drawn into huge black holes. Gradually, the extremely expanding Universe will consist only of massless particles — photons — and black holes. But this will not last forever: due to Hawking radiation, any black hole gradually evaporates. It takes billions of years, but the end is predetermined.
According to Roger Penrose, together with the disappearance of the last black hole in the Universe, there will be no object relative to which measurements can be taken — that is, the very concept of space and time will disappear. The big bang and our world arose. As soon as this happens, a new Universe will emerge from the singularity, and with it a new space-time.According to a group of physicists who have studied the latest data from radio telescopes, irregularly distributed structures, called B-modes, are clearly visible on the CMB map.
It is assumed that it was in these places in the previous Universe that the evaporation of black holes evaporated with the release of so much energy into space that we, the inhabitants of the next world, can still observe the echo of those events.
So far, the world community is waiting for additional evidence of the structures found, and if the data is confirmed, the discovery of scientists can turn the whole modern view of the life and evolution of the Universe.
These are incredible and engaging
