As it turned out, shortly before his death, an outstanding scientist tried to explain the existence of parallel universes, or the so-called. the multiverse.
Prominent British theoretical physicist Stephen Hawking passed away on March 14, 2018. He was 76 years old. Now the media drew attention to the last material on which the researcher worked. The corresponding update appeared in the arXiv.org electronic preprint library on March 4 of this year. The material is devoted to the concept of the existence of the multiverse, or, to put it another way, many worlds similar (or partially similar) to ours.
As you know, in the scientific community there are continuous debates about the beginning and end of the Universe. Within the framework of the currently prevailing provisions, it is argued that she was born as a result of the so-called. Big Bang. A number of scientists believe that this event could have been preceded by the death of the "progenitor" of our Universe.
In his last article, Stephen Hawking, together with Thomas Ertog from the University of Leuven (Belgium), tried to answer a number of questions of interest to the scientific world. They created a theoretical model of the ever-expanding multiverse, represented as a two-dimensional hologram. The researchers focused their attention on the variety of hypothetical other worlds that exist parallel to our Universe. Also, scientists have tried to understand what impact the multiverse has on the world in which we live.
As part of the study, Hawking and Ertog concluded that other universes may not be as diverse as they had assumed. In this case, our Universe can be only one of many worlds, which are determined by a set of fundamental constants and the laws of nature associated with them.
More importantly, Hawking and his colleague have stated the potential for detecting traces of other worlds in the microwave background radiation of the universe. The latter was formed in the first seconds after the Big Bang and can tell a lot about our past. "An intriguing idea in Hawking's work is that the multiverse has left its imprint in the relict radiation that permeates our universe, which we could measure with a detector installed on a spacecraft," said cosmologist Carlos Frank.
Recall that not so long ago another team of scientists spoke about another mystery of the universe. The researchers concluded that "ultramassive" black holes may be much more common than previously thought. Astronomers find it difficult to answer the question of how exactly they managed to grow to such a large size.
