What happens if you put 1 cubic centimeter of neutron star matter on Earth?

Neutron stars are a very extreme type of celestial body in the universe, and their state of matter is different. What would happen if 1 cubic centimeter of material was excavated from a neutron star and placed on Earth?

Neutron star's

Neutron stars are one of the densest objects in the universe, and their extremely high density is related to the way they are formed. Neutron stars are predecessors of stars, except that they are much heavier than the Sun, with masses of 8 to 20 times the mass of the Sun. After such stars have consumed fusion fuel, their cores collapse violently due to insufficient radiation pressure, causing the outer material to explode violently outward, resulting in supernovae.

During the gravitational collapse of the core, the electronic shell of the atom is unable to resist gravity and will be crushed, forming a high-density electron degenerate matter. However, the electron degeneracy pressure still cannot resist gravity, and gravity further compresses the electrons into the nucleus. The nucleus is made up of positively charged protons and electrically neutral neutrons, and the electrons that enter the nucleus combine with the protons to form neutrons.

Because neutron degeneracy pressures are strong enough to withstand gravity and not continue to collapse by gravity, the result is a neutron star composed primarily of neutrons.

The density of neutron stars

In a neutron star, the nuclei are closely arranged, but the nuclei are basically all neutrons. Neutron stars are very dense, their density is comparable to that of the nucleus, reaching 5 10 17 kilograms cubic meters, which corresponds to 350 trillion times the average density of the Sun.

After a supernova explosion, a large amount of material from the predecessor star is ejected into space, and the mass of the neutron star formed by the residual core is usually up to three times the mass of the Sun. But due to the strong gravitational collapse, the radius of a neutron star is only 10 to 20 kilometers, while the radius of the Sun is almost 700,000 kilometers.

Put neutron star matter on Earth

If 1 cubic centimeter of neutron degenerate matter were taken out of a neutron star, then its mass would be as high as 500 billion kilograms, or 500 million tons. What would happen if this material were to be put on Earth? Will the Earth be destroyed?

Neutron degenerate matter can only exist under great gravitational pull, and when they are placed on Earth, neutron degenerate matter will cease to exist due to the absence of gravitational constraints, and they will become free neutrons. Such particles are very unstable and they undergo decay:

The result is protons, electrons, and antineutrinos. Free neutrons have a half-life of only minutes and an average lifespan of only minutes. Decay produces particles that may combine with free neutrons to produce hydrogen or other ordinary matter, and the Earth itself is not destroyed by neutron degenerate matter.

If a cubic meter of neutrons is placed on the earth, it will actually not have a great impact on human life, because after it enters the earth, it will enter decay, and it will become common substances on the earth, such as hydrogen, oxygen, etc., so even if the material on the neutron star is put on the earth, it will not bring any threat to the earth.

Neutron stars, though heavy, are depleted

There are all kinds of stars in the mysterious universe, even the solar system that we are more familiar with, and many planets that we have not been deep into, such as neutron stars. We don't talk much about this planet, but it has one characteristic that people can remember for once, and that is its weight, a small neutron star is much heavier than the sun.

The weight of the entire neutron star is 20 times heavier than that of the Sun, but if one cubic meter of material is taken from the neutron star, that is, about 500 million tons of weight, and put it on the Earth, will it affect the Earth? The answer is no. Because after the neutron star material enters the earth, due to the loss of bondage, these substances become a free state, and after the termination of freedom, they begin to decay, and become microelectronic protons, etc., so the earth will not be harmed by neutron star matter.

As soon as matter leaves a neutron star, it begins to decay

Neutron stars are gradually evolved from stars, and the reason why neutron stars are so heavy is because of the nuclear fusion inside the neutron star after the fuel inside the neutron star is burned, which will cause the radiation pressure on the surface to be insufficient, and the core of the planet will collapse, so that the external matter will be squeezed towards the core of the planet, and the gravitational collapse occurs, and the atoms and electronic shells cannot resist, so the pressure will be directly crushed into pieces, and the electron degeneracy matter will be released.

The density of this kind of matter is very high, but it still can't resist the gravitational force of the neutron star itself, these electronic substances will still be compressed into the nucleus, so the final neutron matter pressure is greater than its own gravity, the density of the neutron star is very close to the atomic nucleus, but once it is cut, these substances will lose its original binding force, if it lacks this super gravitational force, this substance will be released as free neutrons again, and enter the half-life, It takes about 15 minutes or so for the decay process to evolve into hydrogen on Earth. Therefore, even if 500 million tons of neutron matter are put in, there will be no other changes to the earth.

The vast story of the universe is still to be discovered

The volume of a neutron star is not large in the universe, just because of the collapse of its own pressure, which causes all the matter to be squeezed together, and its radius is actually only 20 kilometers, about such a small planet, not even as big as a city, but its weight is unimaginable.

This also confirms from the side that there are still many unknowns in the mysterious universe waiting for us to discover, and many things in the universe are mutually restricted and constant with each other, and human beings can only obtain more information and learn more about the unknown in this vast universe by constantly improving their abilities.

Neutrons are very unstable and will produce radiation, similar to the radiation of a neutron bomb, but the half-life is short, the radiation is not long-lasting, and the power is not very great, if it is placed on the ground, it will kill people within 10 kilometers, and if it is placed at an altitude of 50 kilometers, it will kill people within a diameter of 100 kilometers!

The Earth itself is not subject to neutron degenerate matter.

Then the Earth will be crushed in an instant, because neutron stars are very powerful.

I don't think so, because this neutron star matter of the Indonesian centimeter does not affect the Earth.

The earth may be **, no** may also be detonated at some point.

I think there will be a supernova, which will bring some different changes to the Earth anyway.

I think this will have a big impact on the normal operation of the earth.

It is possible that a chemical reaction occurs because the environment repels each other, and the specific reflection cannot be imagined.

I think it's going to change dramatically, don't you think that's going to happen?

I don't think it's going to be like that, because it's so small.

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.

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.

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.
