The highest mountain range of neutron stars is only1mm. Is it the most perfect spherical object in the universe?

With the continuous development of human science and technology, our understanding of the universe has gradually increased. In the vast universe, there are countless celestial bodies, but they all have one thing in common, that is, their shapes tend to be round. If the shapes of celestial bodies in the universe are diverse, it may be related to many factors, but celestial bodies are all approximate round spheres, so they must bear the same force.

In fact, most of the shapes of celestial bodies have a lot to do with the gravity of stars. Because when the mass of the celestial body is large enough, its gravity is very strong, so it can also realize a sphere with hydrostatic balance. For example, the water spilled by us will flow to the nearest place to the center of the earth, such as reaching the depths of potholes. Although the planet is rocky and seems impossible to flow, the mass and volume of celestial bodies are too huge, so they can flow like water.

In fact, the shape distribution of celestial bodies in the universe is diversified, such as some comets or meteorites. Therefore, in order to better classify celestial bodies, the astronomical meaning is that celestial bodies that revolve around and cannot be spherical are called "asteroids". When a celestial body has a large enough mass and can resist the solid gravity, it can become a planet or a dwarf planet.

For the celestial bodies in the universe, we think that they are all round from a distance, but if we look closely, we will find that many celestial bodies are only roughly round, such as the earth. Originally, scientists thought that the earth was round, but according to calculations, the real earth should be regarded as an ellipsoid. In fact, in the vast universe, there are many celestial bodies that are more round than the earth, among which neutron stars are very round spheres.

When a supermassive star explodes into a supernova, it will produce new celestial bodies, including neutron stars. Neutron stars are very small because they are produced by violent explosions, but they are very huge because electrons enter the inner region to form neutrons. For example, a neutron star with a diameter of only 10 km is very small compared with the earth, but its mass is more than 460,000 times that of the earth.

The mass of neutron stars, which differ greatly from the earth's volume, is much higher than that of the earth, indicating that the density of neutron stars is extremely huge. Compared with the density of neutron stars, the earth is like cotton and iron. However, even the neutron star, a celestial body with terrible density, can't actually reach the extremely round sphere. After all, neutron stars also have the theory of mountains.

Scientists have built a model to explain the existence of neutron star mountain. After analyzing the model of neutron star, it is found that there are indeed mountains and other related terrain on neutron star, but unlike the tall mountains on earth, the height of neutron star mountain range is even only 1mm, which is the height of the flat ground on earth, but it can be called mountains on neutron star, so neutron star is not the ultimate circle, but it is also "perfect" enough.

In fact, in the process of studying neutron stars, scientists should not only prove whether there is a polar circle, but also get information about gravitational waves. The existence of gravitational waves has always been what scientists want to explore, but our research methods are still limited, but we can also understand gravitational waves when studying extraterrestrial objects.

For the relevant data on neutron stars, such as the height of mountains, these are actually not directly observed by scientists, because neutron stars are too far away from us to conduct on-the-spot investigations. Now we can only wait for the development of science and technology, so that we can have a further understanding of neutron star mountain.
