Sina Technology News Beijing time on April 16 news, according to foreign media reports, dark matter is the mysterious extra sending quality in the universe, they do not release light, but it will produce a gravitational effect, may actually be caused by the original black hole originated from the Big Bang .
Currently, according to the latest research theories, the birth of these miniature mini black holes may be related to the Higgs Bugson. This theory was published in the “Physical Review Express” magazine published on March 23. The researchers pointed out that the original black hole It was formed in the action field where the Higgs boson was generated. In the Large Hadron Collider (LHC) experiment, the researchers described the Higgs boson as 'God particle'.
The research co-author, Antonio Riotto, a physicist at the University of Geneva in Switzerland, said: 'In principle, all dark matter interpretation is based on the original black hole.'
However, not everyone is convinced. Some physicists say that these primitive black holes are unlikely to explain all dark matter in the universe.
Mini Black Hole
The Higgs bosons are produced in the so-called Higgs field. They pervade the universe and give quality to the particles. When scientists discovered that the Higgs boson was present, it proved to be more protonic. It was 126 times lighter than most physicists envisioned. After some calculations, physicists realized that the quality of the Higgs boson implies that the Higgs field may not be in the most stable state.
More importantly, the quality of the Higgs boson implies that during the early expansion of the universe, the unstable Higgs field experienced quantum fluctuations as the physics spread out immediately after the big bang. There are different density materials in different parts of the Higgs field.
According to the latest research, these fluctuations have made the mass density of small space areas so high that they collapse into a black hole. The quality of these small mini-black holes is about 10 trillion kilograms, and the quality is similar to Mount Everest.
This theory has certain attractions on many levels: dark matter does not release detectable light, and black holes do the same, while the original black hole, if it exists, will be the physical confirmation that the Higgs field is not in the lowest energy state. This latest theory will also explain dark matter and does not require any new physical concepts beyond the standard model. It describes the behavioral characteristics of tiny subatomic particles.
However, if these primitive black holes do exist, how will physicists discover them? Today, they look like they were born about 14 billion years ago?
Over time, black holes will attract and devour more and more quality. But there may be another kind of action field operation, that is, 'Hawking radiation' of siphon black hole material. The 'Hawking radiation' theory holds that Due to quantum effects, black holes release particles and energy. Over time, Hawking radiation may cause them to evaporate completely. The smaller the mass, the faster they disappear. The particles and energy released by black holes are so quiet and weak that they It has never been detected, although most scientists believe that they are real. Over time, the particles and energy in the black hole get more quality, and these particles and energy are lost through Hawking radiation during 14 billion years of time. The original black hole that remains today may be very tiny or very large.
Controversial theory
The current theory that black holes in the universe constitute all dark matter is still controversial. Physicists have now ruled out lower-quality black holes because there are not enough black holes detected today to explain all the extra mass in the universe. However, physics The family has now ruled out black holes of a medium size, for example: In February 2016, the Laser Interferometric Gravity Observatory (LIGO) detected two black holes in the process of merging. Their masses were 29 and 36 times that of the Sun. The quality level original black hole has not been excluded.
But some physicists question whether these objects can explain most of the dark matter in the universe. The Black Hole physicist Simeon Bird of the University of California, Riverside, said: 'According to what we know today, the original black hole It is unlikely that they are all made up of dark matter. But we cannot be accurate to 1%-10%. To prove this point of view, the easiest way is to detect the original black hole.
Bird emphasized that the Large Synoptic Survey Telescope currently under construction in Chile will be the ideal choice for searching these ancient primitive black holes.
A study written by Marc Kamionkowski, a theoretical physicist at the Johns Hopkins University in the United States, claimed that dark matter is composed of black holes. He maintained similar caution in the report. He said: ' In the past year, I have shaken confidence in the idea that black holes constitute dark matter, because the laser interference gravitational wave observatory did not find sufficient evidence of the merger of black holes to confirm the theory. But I still think this view is very interesting. The latest research report provided an early cosmic mechanism for the generation of black holes, which aroused the interest of astronomers.
The original black hole is still an assumption, unless we detect a black hole of lower quality than the sun, and the creative interpretation of the Higgs field to the researchers cannot be confirmed until the original black hole is found.
Not everyone believes that, as the researchers did, the original black hole and dark matter may be homogenous, but Kamienkovsky claimed in 2017: This is a weird idea, anything about dark matter. Every point of view may also be a crazy idea.
