The theory tells us that our world exists in a continuous cycle of birth and death: that is, our universe had descendants, and after it dies, a new universe will take its place. So how will the end of our universe occur?
A scientist believes that in the distant future, all the particles of our Universe that have mass will gradually be pulled into huge black holes. Gradually, the extremely expanded universe will consist only of massless particles - photons - and black holes. But this won't last forever: because of Hawking's radiation, any black hole will gradually evaporate. It takes billions of years, but the end is predetermined.
According to Roger Penrose, with the disappearance of the last black hole in the universe, there will be no object relative to which measurements can be made - that is, the very concept of space and time will disappear.
It is not only Penrose's name alone that draws attention to this theory; recent discoveries by scientists have provided some evidence for the correctness of conformal cyclic cosmology. The fact is that conformal cyclic cosmology assumes possible presence in our Universe of traces from the previous one. Such traces can be left by the only objects left at the end of the life cycle of the previous Universe - supermassive black holes. If they can somehow be detected, then only by studying the distribution of relic radiation.According to a group of physicists who have studied the latest radio telescope data, the map of the relic radiation clearly shows irregularly distributed structures, called B-modes.It is assumed that exactly in these places in the previous Universe there was evaporation of black holes with release into space so much energy, that echoes of those events we - inhabitants of the next world - can observe until now.
So far, the world community is waiting for additional confirmations of discovered structures, and if the data are confirmed, the scientists' discovery may overturn the whole modern view of life and evolution of the Universe.
