In previous scientific circles, many scientists thought that some stars or planets were formed by the energy generated in the BIGBANG process, and then slowly formed some nebula dust, which gradually merged into stars or planets. Although BIGBANG's theory was later confirmed, he also had many questions that violated normal logic, such as what was the state before the Big Bang? Or did life cover the whole universe before the explosion? It is precisely because of these problems that this big bang theory has not been recognized by all scientists.
Later, with the continuous development of some science and technology, more and more scientists think that this theory is too one-sided. It is precisely because we have never understood this theory that it has been difficult for us to get out of the solar system and make little progress in space exploration.
Now scientists use some mathematical models to infer that there are at least several parallel universes in the whole universe, which can communicate and even interfere with each other through the level of strings. They think that black holes are a door for our three-dimensional universe to be closer to the parallel universe. If we can have a more thorough understanding of black holes, we can master some laws of their intentionality, so that we can use black holes to shuttle to the other side of black holes. Reaching the parallel universe we infer further proves that there is not only life on our earth, but also some more advanced civilizations on other universes or planets. They infer that in many parallel universes, there will be some life that can adapt to the environment like us.
