Second only to the black hole of the horror of the object, a spoonful of mass up to 100 million tons, heavier than the Himalayas

In the previous topic, we often mention the concept of black holes, and we all know how powerful the horror of black holes is in the universe in the end.

As long as the place where the black hole is infested, all the matter around it will be absorbed into it, and even the light passing near it cannot escape the fate of being swallowed by it.

But there is such a kind of object in the universe, which can be said to be second only to black holes in terms of its horror.

The mass of a small spoonful of it can reach 100 million tons, which means that its mass is even heavier than the Himalayas.

We can imagine how dense this kind of object is.

It is almost close to the density of a black hole, and it is the neutron star that we will mention in this issue.

The concept of a neutron star was first proposed by the Soviet scientist Landau in 1932, but for some time afterward, it was only an idealized concept and was not confirmed by scientists.

So the whole scientific development process of neutron stars is similar to that of black holes as well.

Just like black holes, when Einstein proposed black holes, they were likewise not accepted by the rest of the scientific community.

It was only on April 10, 2019, that mankind first photographed a black hole about 55 million light-years away from our planet.

This confirmed that a black hole is indeed an object that exists in the universe and that it is not a concept hypothesized by Einstein.

As we have mentioned many times before, black holes are formed by massive stars that shrink and collapse at the end of their active life, blowing out the outer shell and condensing into an extremely dense object.

The formation process of neutron stars is similar to that of black holes, but why are they less scary than black holes?

One of the most important reasons is that they are formed under different conditions.

According to astronomers, the prerequisite for the formation of neutron stars is that the mass of the star is about 8 to 30 times the mass of the Sun.

And to form a black hole. The mass of the star must be at least 30 times more than the mass of the black hole.

In addition, from the results of the formation after the collapse, the mass of the neutron star after formation is about 1.44-3 times the mass of the Sun.

But there is no clear definition of the range of black holes after their formation so far.

However, it has a minimum value.

According to astronomers, the smallest black holes have a mass of more than three times the mass of the Sun.

So from the data of the stars observed by scientists and the data on the formation of neutron stars and black holes, we can see that the preconditions for their formation are different.

In addition, the mass range after formation is also different, and if a neutron star is formed with a mass greater than 1.44 to 3 times the mass of the Sun.

Then it will continue to collapse and eventually face the result of becoming a black hole.

To put it simply, a neutron star is an intermediate process in the transformation of an object from a star to a black hole, but it has not yet reached the conditions for the formation of a black hole.

Therefore, its density and the degree of attraction are inferior to that of a black hole.

After a star forms a neutron star, the rotation speed of the neutron star becomes rapidly faster.

Astronomers have observed that the fastest neutron star can rotate at 1122 revolutions per second, which is more than 100 million times the rotation speed of the Earth.

While rotating, it also generates a huge attraction, just like a black hole, which attracts all objects around it, including stars that appear in its vicinity and cannot escape from it.

Because of its extremely high temperature, which can reach over 1 million degrees Celsius, a neutron star consumes its energy very fast.

Although a neutron star is not the final process of a star's evolution, it is one of the most terrifying objects in the universe for the time it exists.

Let's take an example of a neutron star with a diameter of about 10km. The thickness of the outer shell part can reach about 1km. Its interior is composed entirely of neutron fluid.

The density can reach more than 100 million tons per cubic centimeter.

So when it comes to this, you may not intuitively feel the density of neutron stars, we use our Earth to make a comparison.

You can understand, that if we compress our Earth as a neutron star, then this neutron star evolved from the Earth, it is only about twenty meters in diameter.
