The question of whether alien life forms exist, in what form and what conditions they can exist, is open to debate and is a subject of speculation. The nature of dark matter and black holes also remains a mystery. There is a purely hypothetical assumption that alien life forms can be found in these mysterious parts of the universe. These are the prerequisites for such theories.
Scientists do not know what dark matter is, despite the fact that it is estimated to make up 25% of the known portion of the universe. A popular theory is that it is made up of different particles that destroy each other when they collide, and in this process energy is released.
This energy is capable of heating planets located inside dark matter, creating conditions for life, according to physicist Dan Hooper and astrophysicist Jason Steffen of the National Accelerator Laboratory. Enrico Fermi.
To create enough heat, a very high density of dark matter is required. Therefore, although dark matter is widespread, it is unlikely that it can create conditions for life on a large scale, Hooper explained in an interview with Space.com. in 2011
“We're talking about rare and special conditions, but which are very likely,” says Hooper. "You can have all the basic elements you need to live without a star."
Dark matter can provide heat to planets for trillions of years, while stars, the size of our Sun, die after 10 million years.

Professor Vyacheslav Dokuchaev from the Russian Academy of Sciences in Moscow put forward an unusual theory about black holes, published in the Journal of Cosmology and Astrophysics in 2011. According to the generally accepted theory, any object that falls into a black hole is split into particles by forces inside the hole.
But, according to Dokuchaev's calculations, planets suitable for life may exist in black holes. In such places, particles and planets can have stable orbits, despite the fact that their orbits may be unusual, Discovery News reported.
These planets can be heated by protons moving in the same orbits and a singularity located in the center of the hole. The singularity is very small, but it has tremendous power; scientists do not have reliable data on this phenomenon. Photons and singularity can promote life like the sun.
Dokuchaev writes: “A supermassive black hole is not the best place to live. However, there are physicists who believe that life can exist in such extreme conditions and, perhaps, these places are already inhabited by very advanced alien races."
Stuart Gary, presenter of the Australian radio ABC Newsradio, described Dokuchaev's theory in an article on Discovery News: "This idea looks far-fetched and may be wrong, but it raises many philosophical questions."
He asked another astronomer what he thought of Dokuchaev's theory. Dr. David Floyd of the Australian Astronomical Observatory and the University of Melbourne replied that other conditions may contradict Dokuchaev's theory, but added: “Given the huge number of black holes in the Universe, it can be assumed that life is inevitable in at least one of them, if there really stable orbits exist. Maybe there are entire universes inside black holes."
