Discover the size of the largest black hole to date
A black hole is a special substance that exists in the universe.Because of its huge gravitational force, light enters There is no escape from it, and we can"t observe what matter is in the black hole.As of November 28, 2019, the Chinese Academy of Sciences has discovered the largest black hole to date, with a mass about 70 times the mass of the sun, breaking the previous black hole record.
Since ancient times, people"s exploration of the universe has never stopped.In ancient times, this kind of exploration of the universe was combined with mysterious metaphysical colors.The ancients combined the cosmic astrology with human numerology, and then astrology appeared.Learning, Book of Changes and many other mysterious ancient cultures.Today, people are still studying the universe, but this research has added more scientific methods, so people have discovered that in the universe, in addition to various planets that can emit light or refract light, there are celestial bodies that cannot emit light and cannot refract light.It"s what we call a black hole.
Discover the size of the largest black hole so far
Although black holes cannot be observed, we can use some methods to measure the mass of stars, and the mass of stars is an important basis for judging the size of stars.In the fall of 2016, the research team of the National Astronomical Observatory discovered a huge celestial body while studying the subject of double stars, and then conducted research on this celestial body.After more than two years of detection, on November 28, 2019, the research team published the research results of this celestial body in the international academic journal "Nature".This celestial body is a black hole, and this is also the largest black hole discovered so far.Its mass can be 70 times the mass of the sun.
What exactly does a black hole mean
Although a black hole is called a black hole, it is not black or a hole, but a special cosmic celestial body, which is a Special substances that exist in the universe.Black holes are mainly created by stellar explosions.When a star is dying until it explodes, the matter in the star will quickly decompose into neutrons and shrink.After shrinking, these neutrons are compressed into another celestial body.This celestial body has a huge gravitational force and can even absorb light.Its internal structure cannot be detected, and such celestial bodies are what we call black holes.
