In May of this year, information about the work of Stephen Hawking, in which our universe is considered as part of the "Mega-Universe", appeared. The scientist conducted research together with his colleague from Belgium, Thomas Hertog. It turned out that this was not the last work of Stephen. More recently, the press got information about another project, which a famous scientist was engaged in just a few days before his death. When Hawking died, the article "brought to mind," the professor at the University of Cambridge, Malcolm Perry.
The studies of the late scientist were devoted to the study of the information paradox: Stephen tried to understand what was happening with the information in black holes.
Hawking theory
In his previous works, the scientist repeatedly asserted that Albert Einstein’s assumptions about this phenomenon were incomplete, highlighting only three signs of similar space objects: mass, charge and spin. Hawking assumed that black holes, at a minimum, also have temperature.
Steven believes that all massive objects in outer space lose heat, this can cause the evaporation and disappearance of black holes. Although this process is contrary to the laws of quantum mechanics. Hawking's work does not provide answers to all questions, but simply makes some assumptions.
The article was called "Black Entropy and Soft Hair", which is a kind of reference to the process of absorbing information by a black hole. This phenomenon is called the "hair" of the black hole.
Scientists have suggested that an object caught in a black hole will change its temperature. This quality is called entropy or energy dissipation. Information about the changes would presumably be stored in the form of a small number of photons or “soft hair”.
“The work allows us to assume that“ soft hair ”can tell about current events with the entropy of a black hole. Of course, we cannot say with complete certainty that entropy responds to all objects falling into a black hole. already progress in the study of this mysterious cosmic phenomenon ", - shared his impressions Malcolm Perry.
"Stephen was already very difficult to communicate. I had to turn on the volume to maximum so Stephen would hear the results of the study. Although I am sure that he already knew the final result," says Perry.
