Chapter 197 - 196 Neutron Star Defense Line
Constant Star Lu Chen, while tearing and absorbing a constant star within the Ring Nebula, as well as the Wandering, Green Star, Earth Civilization, and Light Synthesis Civilization when annihilating the colonization stars of Ant-man Civilization, all discovered traces of neutron stars within the Ring Nebula.
The Wandering Alliance discovered a total of three, all of which were special celestial bodies formed from the star core parts left over after the death of medium-mass stars.
They are a kind of celestial body that lies between White Dwarf Stars and Black Holes.
The density of neutron stars is extremely high, reaching 8^14 to 10^15 grams per cubic centimeter. Perhaps everyone has no concept of this kind of density, but this density equates to the weight of the material inside each cubic centimeter exceeding a hundred million tons.
Imagine how big is a cubic centimeter?
With length, width, and height each being one centimeter, not even as large as a marble, yet the weight of the material in such a small space is more than a hundred million tons, simply unimaginable.
If Earth were compressed to this density, the Earth, with its mass of more than a dozen planets, would only have a diameter of 22 meters. If the Sun, with a constant star mass of 1250, were also compressed to this density, its diameter would only be about ten kilometers!
The reason why neutron stars have such a high density is because the internal pressure forces matter to exist in the state of neutrons, which means neutron stars are actually celestial bodies composed of closely packed neutrons, hence the origin of the name "neutron star."
