If the black hole absorbs all kinds of matter including light, why does it not grow and swallow everything?

The new hypothesis of Professor Leonard Susskind, a famous physicist and black hole expert, will make you scratch your head.

Black holes can be sucked into any material, even light cannot escape them. But if "eating" so much, why don't they grow up, grow bigger and bigger and then swallow the whole Universe? To answer this question, one of the leading physicists gave his opinion.

And by the way, the idea of ​​Mr. Leonard Susskind - a physicist from Stanford University, one of the people who gave birth to string theory - connected the two biggest hypotheses in physics.

In a series of scientific reports, Mr. Susskind made the remark that the black hole grows out by increasing the complexity of its PARTY structure. From a distance, we will not know the complex structure of the black hole and how it works exactly. To put it more simply, black holes increase the area deep inside, not expand.

And yet the good: The theory that Mr. Susskind offered seems to go against the claim that the Universe is still expanding. "I have a lot of thoughts on a very interesting question, whether the expansion of the Universe is connected to something more and more complicated over time," Susskind told The Atlantic.

"And whether the Cosmic clock, the evolution of the Universe, is linked to the evolution of complexity. That's something I don't understand." Mr. Susskind talked a lot about the evolutionary aspect of the Universe, but what he wrote about the black hole growing deep inside was also worth mentioning.

It must be made clear that Susskind's current research has not been reviewed by leading scientists, still carries a great deal of theory, so it cannot be confirmed what he argued is obvious.

Turn over a little old knowledge: black hole is a solid block of material, affecting the whole space around it. Black holes suck everything in, including light. The first theory shows that in the universe there are such objects as Einstein's general theory of relativity, published in 1915. Since then, more space objects have been discovered. , usually located at the center of a galaxy. In our Milky Way galaxy, there is a black hole Sagittarius A .

Space space in the Universe can be described as a large blanket. A very heavy object will cause the blanket to sag, equivalent to bending space-time. The nature of the blanket will be very deep, so there may be gravity tunnels deep down from the ground level.

Most things when they receive more material will come out, not deep inside. The existence of a black hole makes it possible to compare the Universe with a shaky blanket: when you drop a heavy ball on a stretched blanket, it pulls the blanket down deeply, while the mouth of the hole is created. It will get bigger and bigger. The black hole is not like that, the mouth is not wide but it is getting deeper and deeper.

Why do particulate matter work like that? Fortunately, in addition to the physical concept of relativity, we have another book "How to operate the universe" (no book at all, just a hint), named quantum mechanics. It explains how particles and forces around particles interact, however, many years of reading researchers still do not fully understand the book of quantum mechanics.

But the theory of relativity and the theory of quantum mechanics do not match. Huge things like black holes don't follow quantum mechanics, tiny matter particles don't follow relativity. Finding a bridge between the two, we will unlock (almost) all of the Universe mysteries.

One of the potential bridges is the anti-de Sitter correspondence / adaptive field, abbreviated Ads / CFT, consisting of two halves of quantum gravity and the quantum field hypothesis. Based on the Ads / CFT framework, the quantum complexity of a black hole - the number of steps required for a black hole to return to its state when it has not become a black hole - is closely related to the volume of the hole itself. black.

Simply put, the inner complexity of the black hole is what has made it more and more deep, and it is only deeper / more complicated when it comes to matter, not spreading everywhere, swallowing everything. stuff. The black hole is different from the rest of the universe, so it cannot require it to follow the rules we know.

Although no one has analyzed it yet to confirm that Professor Leonard Susskind's research is correct, we cannot ignore the expert's words. If in the past, Albert Einstein's hypotheses were not taken seriously, how would humanity grow so slowly?
