Neutron stars are extremely strange and awe-inspiring objects in the universe, with extremely high density, evolved from massive stars. To understand why neutron stars are scary, we first need to understand their extreme nature.
Neutron stars are unusually dense, often containing tens of millions of tons of material per cubic centimeter. This astonishing density stems from the gravitational collapse of the star's interior when neutron stars form, making the nuclei very close to each other, with few gaps. Therefore, even though the size of a neutron star is relatively small, its mass is equivalent to several times the mass of the Sun, resulting in an extremely strong gravitational field on the surface of the neutron star.
With a weight of 2 billion tons per cubic centimeter, we can reveal the horrors of neutron stars with a few simple calculations. First of all, considering that the density of matter on Earth is about 1 gram cubic centimeter, the density of the latter is several orders of magnitude higher compared to neutron stars. This makes the gravitational field of neutron stars extremely strong, and even a slight proximity can be subject to a strong gravitational pull.
If a person falls onto a neutron star, the person will experience extremely violent tidal forces due to the extremely strong gravitational pull of the neutron star. The tidal force is due to the gradient of the gravitational field, i.e., different gravitational forces are experienced by different parts of the object. Under the extremely strong gravitational field of the neutron star, the person's body will be stretched extremely long, and this pull may cause the body to tear apart, or even tear into fine fragments at the atomic level. The situation is similar to the tidal gravitational pull on Earth, but the effect is correspondingly more extreme because the gravitational pull of neutron stars is much stronger than that of Earth.
In addition, the strong magnetic field on the surface of neutron stars is also a factor that cannot be ignored. The magnetic field of a neutron star can be millions to billions of times stronger than that of the Sun and far exceeds that of the Earth. When a person falls into a neutron star, he will be affected by a great magnetic field, which may lead to the separation of the internal charges in the body, triggering a strong electromagnetic effect, which in turn will cause fatal danger to living organisms.
Due to the extreme conditions of neutron stars, even light cannot escape their gravitational field, so neutron stars are visually dark. If a person is on a neutron star, not only will they be devastated by strong gravitational and tidal forces, but they will also be completely dark around and will not be able to see any light. This makes the neutron star an environment full of dangers and terror.
Overall, neutron stars are scary because of their unusually high density and strong gravitational field, as well as the extreme tidal and magnetic effects that come with them. If humans were on the surface of a neutron star, they would be severely affected and would not be able to survive like never before. This celestial body exhibits an extreme state of evolution in the universe under extreme conditions in nature, providing us with unique insights into the mysteries of the universe and the behavior of matter in extreme environments.
