If a neutron star is close to Earth, will it be absorbed by Earth?

A neutron star is close to the Earth, and it will not be absorbed by the Earth. A medium star is a supernova that a star has evolved over a long period of time and finally becomes a supernova, a product of supernova produced after passing through **. Although the neutron star has become smaller in size after supernovae**, its density has increased.

If a neutron star is close to the Earth, it will not be absorbed, it will exist in two ways, one is away from the solar system. If the neutron star wants to get close to the earth, but does not enter the solar system, then the earth will not be affected by the neutron star, even if the gravitational pull of the neutron star is particularly large, and the destructive power of the neutron star is also very large, but it will not affect the earth, and it will not cause any harm to the earth.

Another way for a neutron star to get close to Earth is when it has already entered the solar system. At this time, the earth will be affected by the gravitational pull of the neutron star, and the earth will slowly deviate from its original orbit, and then slowly be affected by the repulsive force of the sun and be thrown out of the solar system, which is a devastating disaster for the earth. After the Earth is separated from the original orbit of the solar system, neutron stars will not be absorbed by the Earth if they get close to the Earth, but will be broken by neutron stars, so the Earth will be produced and destroyed.

At that time, humanity will cease to exist, and the earth will disappear from the universe forever.

If there is a neutron star with a particularly small diameter, and he falls to the earth, then the neutron star will continue to fall due to the gravitational pull of the earth, but because it will fall faster and faster, and the mass of the neutron star itself is very high, and finally the neutron star will fall straight and insert it on the surface, and then continue to fall down, constantly pointing to the center of the earth. At this time, the destructive power of the neutron star is equivalent to that of an asteroid hitting the earth, and human beings will have a significant sense of vibration for the fall of the neutron star. Eventually, it will be found that there is a very large crater on the surface where the neutron star falls, and this pit is much larger than the neutron star.

No, if the neutrons are close to the Earth, they will be repelled by the Sun if they are still in the solar system, and it will not cause any effect. If a neutron gets close to the Earth and enters the solar system, the Earth will be out of its original orbit.

In the universe, the earth is relatively small, and a seed close to the earth, it will not be absorbed by the earth, because of the existence of gravity, so this neutron will be close to the earth, and it will be exhausted when it passes through the atmosphere.

I don't think it will be absorbed by the earth, after all, the attraction of the earth is not very strong, but it should be worried about whether the neutron star can attract the earth to it.

If the neutron star is dense enough, it will crash into the Earth's core and will also change the Earth's orbit, bringing it closer to the Sun.

No, but as a neutron star approaches Earth, it will change the gravitational pull of the solar system, causing the orbits of other planets to change, and even bring disaster to Earth.

At least according to current science, no neutron star can threaten the safety of the Earth, because all the neutron stars known today are far from the Earth.

If the neutron star material falls to the earth, because it is extremely massive and small, the pressure on the ground is unbearable for the earth's rock formations, so the neutron star material can pass through the earth's rock layer because of the gravitational relationship and pierce the earth through a hole, and because the rotation of the earth and the gravitational potential energy of the neutron star material is extremely large (because of its mass), it will repeatedly make holes in the earth's interior and cause unpredictable consequences, but this seems impossible at present, because the gravitational attraction between the parts of the neutron star is very strong, It is simply not possible to remove a piece of neutron star matter at present.

However, some of the above statements are inaccurate, in fact, the gravitational potential energy is shared by neutron star matter and the Earth, and it is only for the sake of simplification that I say that.

There are a lot of massive stars in the universe that collapse under their own gravitational pull when they run out of nuclear fuel, they are often in supernovae**, and when it's all over, if the mass of its remnant core is greater than the mass of a solar (Chandrasekhar limit) and less than the mass of a solar (oppenheimer limit), it is a neutron star of Zino.

If the Earth were compressed to the average density of a neutron star (second only to the density of a black hole), its radius would shrink from 6,371 kilometers to about 11 meters. Then an interesting question arises: what would happen if 1 cubic centimeter of neutron star matter was gently placed on Earth?

The radius of a neutron star is generally 10 km to 20 km, the larger the radius, the greater the density, theoretically, the minimum density of a neutron star is about 80 million tons per cubic centimeter, and the maximum density can reach 2 billion tons per cubic centimeter, for the convenience of discussion, we might as well take an easy to calculate median, that is, 1 billion tons per cubic centimeter.

In other words, a cubic centimeter of neutron star weighs 1 billion tons of matter, so what happens when you put it on Earth? This equates to a billion tons of object on the Earth's surface with an area of only 1 square centimeter (assuming it is a regular cube), and we don't need any calculations to conclude that there is no material on Earth that can withstand the pressure on the Earth's surface caused by this mass of neutron star matter, and therefore this mass of neutron star material will fall almost unhindered by gravity towards the center of the Earth.

But the neutron star material does not reach the center of the earth as expected, and the density of the neutron star material can maintain this tremor or so much because of the gravitational pull of the neutron star itself, and when it comes to the earth, the force that binds the neutrons disappears, coupled with the high temperature of the neutron star material (the surface temperature of a stable neutron star is about 1 million K), so the volume of the neutron star will increase rapidly.

Because his existence in the universe is due to the restraint of gravity, if he is placed under the earth, he will lose this bondage, so that he will transform into a free neutron and decay, which will not cause great impact and damage to the earth.

The Earth will produce hydrogen or other substances that are not commonly used, but the Earth will not be destroyed by these materials quickly, so I don't think the dust will have any effect on the Earth.

It will penetrate the earth, and the mass of the neutron star is very large, and the earth has no way to bear it.

Neutron star, is the mass of the sun 4-8 times the star, in its own fuel is about to burn out, the last completely **, due to the huge pressure, the electrons in the atom are pressed into the protonucleus, so that the center of the material forms a very dense neutron cluster, that is, the neutron star, straight through about 30 kilometers, the rotation speed is extremely high, thousands of revolutions or even tens of thousands of revolutions per second, the density is equivalent to the density of the atomic nucleus, per cubic centimeter of 100 million tons or more, per cubic meter of more than 100 billion tons. That's a lot worse than the density of our planet.

If you put a cubic meter of neutron stars on Earth, because the density of rocks on Earth is negligible. So, it's like dropping a rock from an airplane and falling all the way down. In the same way, this one-cubic-meter neutron star can press all the material on the earth below it to its surroundings, and this neutron star can fall all the way to the center of the earth, and the rotation speed of the earth will also decrease slightly.

Three people become tigers, this is definitely the most appropriate metaphor for the study of the universe! What a singularity, what a black hole, what a neutron star, it seems that if you don't agree with you, you are unprofessional, although these things have not been detected by human beings at all so far, but as long as there is an authority such as Hawking, then predict, they will be considered to exist, and can also be used as evidence to speculate on some other things, although this does not conform to the argumentation procedure, but this can not be seen in a conventional way, and the so-called scientific truth must be guessed with a broader theory of relativity, or even a general theory of relativity. For example, in the composition of matter, I would guess that any matter is made up of two basic particles, one with only mass and no energy, and the other with only energy and no mass.

For example, photons have energy and no mass.

Neutron star, in the universe, is a strange star, the number in the universe is not too small, according to its characteristics, can provide navigation for human space navigation, this aspect of the practice, Chinese scientists have been carried out. In addition, recently, according to the observation of China's Tianyan in the past year, Chinese scientists announced the discovery of 100 neutron stars at one time, which greatly surpassed the achievements of foreign countries for decades. Neutron stars, although very far away from us and scattered all over the universe, play an extremely important role in the future of human beings to travel the universe.

If, like the subject, put it on the earth, it is neither possible nor meaningless.

A 1m neutron star, its mass is as high as a quadrillion, its density is very high, the structure is also unstable, and it will blow the earth apart if placed on the earth.

There will be a terrible phenomenon, because this substance reacts very violently, has a strong flammability, because the unique gravitational pull can lead to the destruction of the earth.

The density of neutron stars is very large, the mass of a seed star in one cubic meter is 100 billion tons, it is denser than any matter on Earth, if it is placed on Earth, it will run through the Earth, but this situation is not possible and will not appear.

According to experimental data, a cubic neutron star material does not occur when placed on Earth, because it does not react with any medium on Earth.

It could bring devastating disaster to some of the creatures that burn on Earth's Forest. Life on earth will be very unaccustomed to the magnetic field of this kind of material, and it will also cause pollution of the surrounding environment.

It will quickly enter the center of the earth, and at the same time will continue to expand, releasing a very large amount of energy, which will bring a devastating blow to the creatures on the earth.

The next thing we see is that the Earth's surface, which is subjected to neutron star matter, is very heavy and second only to black holes in terms of mass.
