There may be a "giant black hole" in the universe


  larger than the "supermassive black hole" in the center of the galaxy

  Science and Technology Daily News (Reporter Liu Xia) According to a report by the Physicist Organization Network on the 20th, a new study by British scientists has shown that there may be a kind of "stupendously large black holes" in the universe, which is better than the one located in the center of the galaxy. "Supermassive black holes" (SMBHs) are even bigger.

If it can be confirmed, it will provide researchers with a powerful cosmological research tool to deepen people's understanding of dark matter and the early universe.

  Existing opinions generally believe that supermassive black holes are formed in the host galaxy and grow by consuming surrounding stars and gas, or merging with other black holes.

Their mass is between 1 million and more than 10 billion times the mass of the sun.

  But in the new study, a team led by Bernard Carr, Emeritus Professor of Physics and Astronomy at Queen Mary University of London, proposed that "supermassive black holes" may have another way of forming, allowing them to circumvent this upper limit of mass.

They believe that these "giant black holes" may be "primitive black holes", formed in the early universe, well before the formation of galaxies.

  Such "primitive black holes" are not formed by collapsing stars, so they have a wide range of masses, which can be very small or very large.

Carl said: "We already know that there are black holes of various masses, such as a small black hole 4 million times the mass of the sun in the center of the Milky Way. Although there is no evidence for the existence of'giant black holes', it is conceivable that they may Exist, they may also live in the space of galaxies outside the galaxy. But so far, the scientific community has ignored the existence of'giant black holes'."

  The research team believes that "giant black holes" help to better understand dark matter.

In the 1970s, Carl and Stephen Hawking proposed that “primitive” black holes may be one of the candidates for dark matter. In the very early days of the universe, fluctuations in the density of the universe may cause some areas of the universe to collapse.

  Carl said: "'Huge black holes' themselves cannot provide dark matter, but if they really exist, they will have an important impact on the early universe and make it possible for the lighter'primitive black holes' to form dark matter."
