Why the Sun ends up becoming a black hole

At first, a large amount of gas (mostly hydrogen) is attracted by its own gravity and collapses into a star, and when it collapses, the gas atoms collide more and more frequently (and at higher speeds), making the gas hotter and higher, and the molecular thermal motion intensifies, and the hydrogen atoms collide at extremely high speeds, so that when they collide, they do not bounce off but converge to form helium. Like the hydrogen bomb**, it releases a lot of heat, and the extremely high temperature increases the pressure of the gas to reach the equilibrium point with gravity (that is, it is neither affected by gravity and continues to collapse, nor expands outward due to air pressure), however, with the consumption of fuel, the heat that can be provided is less and less, and gradually it cannot resist gravity, so the star begins to continue to collapse (don't think that the more initial fuel of the star, the longer it will live, because the greater the mass of the star, the greater the gravitational force, the more heat required to fight gravity, the faster it will be consumed, Our sun can live for another 5 billion years, and some big stars can consume the same amount of heat in 100 million years). If the mass of a star is less than the Chandrasekhar limit (such as the Sun, the Chandrasekhar limit is one and a half times the mass of the Sun, below the Chandrasekhar limit it will not collapse into a black hole, and if it is exceeded, it will.

The Chandrasekhar limit was calculated in 1928 by an Indian graduate student, Chandrasekhar) will not collapse into a black hole, so our sun will not become a black hole!

This paragraph is inducted by me from a brief history of time written by Stephen Hawking, and it is not my own explanation!

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 exceeded.

At this value, there will be no force left to compete with its own gravity, causing another Great Collapse.

The sun can't become a black hole, and it can't get to a white dwarf.

About 4 billion years later, the Sun will expand and collapse in response to pressure, and its edge will just pass over the Earth.

Then the earth will be gone. Ay.

Reason: After the sun's hydrogen fusion activity converts a large amount of hydrogen into helium, helium will continue to fuse, and finally the sun will bear the pressure of helium fusion. Exploded.

Look at it, the origin of the universe** is roughly known. To tell the process inside, it is still very complicated, without going out of the nuclear reaction to reduce the decrease in heat and luminescence, the increase in atomic density, and the increase in gravity. Push the story of the universe!

The mass of the Sun did not reach the Chandrasekhar limit and could not have evolved into a black hole.

It does not reach a critical mass and cannot become a black hole.

Let's not worry about this, it's a lot of "one" years.

Scientists have calculated the situation.

If the Sun collapses into a black hole in an instant, but only the Sun itself collapses, with no other planets or matter involved, then the Sun will still shine on the Earth within a few minutes after the Sun collapses. After about 8 minutes and 20 seconds, darkness descended on the earth, and the earth entered eternal darkness, and there was no more light. The Earth will become a completely frozen planet in a few months to a few years.

Other than that, it's business as usual on Earth.

Because the gravitational pull of the sun itself collapses, the supergravity of the black hole only affects the vicinity of the sun. In terms of the curvature of space, it is as if the original space had a sinking pit (the curvature of space-time caused by the sun's gravity). After the Sun collapsed into a black hole, the crater became deeper and deeper (hence the name "black hole"), but the size of the pit did not change.

Therefore, the space-time structure of the solar system will not change, and all the planets in the solar system (including the planets closest to the Sun and Mercury) will continue to orbit around this "vanished" Sun in their original orbits.

In other words, after the Sun collapsed into a black hole, the mechanics of the solar system were as normal.

Hello dear, I'm glad to answer for you, the reason why the sun has a black hole is that scientists estimate that there are about 90% of dark matter in the universe. Generally speaking, in the universe, celestial bodies with a certain mass generally exist in the form of stars, while black holes are caused by the death of massive stars and the formation of unusually dense and gravitational sensitive bodies after the collapse of their huge self-weight.

Therefore, as long as there is a large enough amount of stars, after their death, they are likely to form black holes. And there is no shortage of massive stars in the universe.

Summary. The reason the sun has a black hole is that it is less dense than the surrounding matter and has a lower temperature, which is what makes a black hole.

The reason the sun has a black hole is that it is less dense than the surrounding matter and has a lower temperature, which is what makes a black hole.

The first is that Taisun told Lao Yang that he would not become a black hole. The second Sun is an ordinary yellow dwarf star, and its mass is too small to generate a strong enough gravitational pull to collapse into a black hole.
