What did black holes make of, and what did black holes come from?

It is likely that black holes also evolved from stars, and when a star ages, its thermonuclear reactions have exhausted the fuel (hydrogen) at the center, and the energy produced from the center is running out. In this way, it no longer has enough strength to carry the enormous weight of the shell. So under the weight of the shell, the core begins to collapse until it finally forms a small, dense star that regains its ability to balance with the pressure.

Stars with less mass mainly evolve into white dwarfs, while stars with more mass may form neutron stars. And according to the calculations of scientists, the total mass of a neutron star cannot be greater than three times the mass of the Sun. If this value is exceeded, there will be no force left to compete with its gravity, causing another collapse.

This time, according to scientists' conjectures, matter will march inexorably towards the central point until it becomes a "point" where the volume tends to zero and the density tends to infinity. And when its radius shrinks to a certain point (Schwarzschild radius), as we described above, the huge gravitational pull makes it impossible for even light to shoot outward, thus cutting off all contact between the star and the outside world - and the "black hole" is born.

Black holes, the density is infinite!

In addition to black holes, the heaviest matter in the universe should be quark stars.

Usually, in the nucleus, protons and neutrons are connected by mesons, and the nucleus density does not change regardless of the type of atom. The team's scientists used Japan's high-energy accelerator to conduct experiments in which elementary particles called k-mesons were injected into the nucleus of a helium atom containing two protons and two neutrons. It was found that one proton flew out, and the k meson was tightly connected to the other proton and 2 neutrons, and when the k meson was tightly connected to the proton and neutron, the nucleus showed a density 10 times higher than the usual nucleus.

Scientists have been observing "quark stars" in the universe. Unlike neutron stars, which are formed by great gravity, quark stars are denser than neutron stars and are thought to be formed by strong interactions. If the high-density state of k-meson formation is established, it is of great significance to the study of the existence and formation process of quark stars.

Its density can reach an average of 10 grams to the 22nd power per cubic centimeter.

Black holes are formed in such a way that the star burns up and then collapses into a white dwarf. If it continues to collapse to a certain extent, it will become a neutron star, which is very dense, weighing about 10 million tons per square centimeter.

When it collapses to an infinitesimal point, it becomes a black hole. I'm going to make sense of it, and I'll give it to me.

Theoretically, a sun-like star will explode into a white dwarf at the end of its evolution, while a star with a mass of the sun can form a neutron star, and a star with the mass of the sun can form a black hole at the end of its evolution.

In addition, white dwarfs and neutron stars can also be formed after absorbing enough mass. ,7,The black hole is formed by the collapse of the inner core of the star ** (supernova large**) that is about to be destroyed, because the mass after the collapse is extremely large, so the gravitational pull of the black hole is super strong. And it is also a phenomenon after the gravitational force is out of control.

Because the gravitational pull of a black hole is so strong that light cannot escape, it can only be observed by measuring the distance between the planets, 2, massive stars, 2, the mass of massive stars getting old, and the mass of such stars is more than 2 times greater than the mass of the Sun. , 2, Black holes evolved from stars. The mass of such stars is more than 2 times greater than that of the Sun.

Hope, thank you! 1. The process of black hole creation is similar to that of neutron stars; The core of the star rapidly contracts and collapses under the force of its own gravity, resulting in a strong **. When all the matter in the core becomes neutrons, the contraction process stops immediately, and is compressed into a dense star, and at the same time compresses the space and time inside, 1, the gravitational force collapses when the big sun dies, and finally after throwing out a part, the rest is infinitely compressed, 1, at the end of its life, the supermassive star collapses into a white dwarf star due to its inability to resist its own gravitational pull, and then collapses from a white dwarf star into a neutron star, and finally collapses into a black hole, 0, the star of a small black hole is formed by changes, It is possible that black holes were the first thing in the universe to appear, and then there were galaxies, and each galaxy has a superblack hole at its center. ,0,
