With a diameter of only a few tens of kilometers and a weight larger than the Sun, why is the densit

There is such a celestial body in the vast universe, its diameter is not large, only a few tens of kilometers, and the volume of some asteroids in the solar system is about the same, but its density is amazingly high, each cubic centimeter can reach a weight of 2 billion tons, several times larger than the weight of the sun, this magical object is a neutron star. Neutron stars are the second densest objects in the universe after black holes, so why are neutron stars so dense?

The predecessor of a neutron star is also an ordinary star, and at the end of the life of these stars, depending on the mass of the original star, a white dwarf or neutron star will be produced. A star of mass like the Sun will become a white dwarf in billions of years. Neutron stars are generally more massive than white dwarfs, and to produce a neutron star, the star must be at least 8 times more massive than the Sun.

At the end of the evolution of massive stars, the hydrogen element of the star is burned out, so the violent nuclear fusion reaction inside stops, and the balance between the gravitational pull of the star and the heat generated by fusion will be broken, triggering a violent **, which is the most brilliant supernova explosion in the universe.

Unlike the case where the outer layers of a star are scattered due to **, the inner core of a star is frantically squeezed under the strong gravitational pull, which is so strong that it can press electrons from matter into the nucleus to form neutrons. Under this pressure, a bunch of neutrons are tightly bound together, which is why this celestial body is called a neutron star.

The whole process of collapse turned the star, which was originally several times larger than the sun, into a small celestial body of only a few tens of kilometers, and so much material gathered in such a small volume naturally became quite dense.

Some astronomers believe that in order for a neutron star to maintain its own neutron state of matter, its energy consumption is very fast and it rotates very quickly. Therefore, the entire life cycle of a neutron star is relatively short, after which it becomes a black dwarf, and there is no possibility of further density.

Some astronomers believe that, in addition to black holes, there should be an object that is denser than a neutron star, called a quark star. These astronomers believe that the gravitational pull of neutron stars continues to increase, and the internal nuclei will also be crushed, continuing to shrink into more basic particles - quarks, hence the name quark stars.

These quark stars are smaller than neutron stars, and of course their density and gravitational pull are an order of magnitude larger than neutron stars. Although quark stars have not yet been discovered by human beings, astronomers who support the existence of quark stars believe that the reason why humans have not discovered quark stars now is only because its gravitational pull is so great that some light cannot escape, so it is not yet visible at the current level of human observation.

Of course, astronomy as a science, it is normal to have different opinions, and I believe that with the continuous progress of human space technology, scientists will find more evidence to solve the doubts in our hearts.

Because the predecessor of the neutron star is a star larger than the sun, and it is subjected to a lot of pressure during the whole process of the explosion and collapse, the volume is squeezed, which is why it produces such a large density.

Because the mass of a neutron star is very large, the nucleus inside will continue to expand during the heating process, so the weight is very heavy.

This is due to the formation of neutron stars, which are also made up of stars, so they are very dense.

Because the gravitational pull of the neutron star planet is very large, it is so dense, which is greater than the weight of the Sun.

Because a neutron star is a star without the space directly of atoms and the space within atoms, most of the mass of matter comes from the nucleus, and they lose space while retaining mass, which is why the density is so huge.

Because these things are bound by the resultant force, their density will be very large, and the neutron star density can put a lot of things.

This is because the density in a neutron star is very similar to the density of the neutron star itself. It even exceeds the sun, so the density is particularly large.

This is because the gravity of the core of a neutron star is particularly large, so the density is very large, second only to that of a black hole.

A neutron star with the mass of the Sun is most likely to be equivalent in size.

a.It's about the same as Qi Wu Moon.

b.There should not be much difference with the earth.

c.It's about the same as the sun.

d.It is also related to the ascension chain within the urban area of our regular city.

Correct answer: Noisy Sun D
