Personally, I don't think it will be neutron colloid. We usually have gaseous, liquid, solid and plasma states. Judging from the differences of these states, the distance between particles decreases in turn. Plasma state can be regarded as a high-energy form of gas, so it can be classified as gaseous state. Neutron stars are atoms compressed, the nucleus dismembered, and the electrons and neutrons inside are very close, just like the emperor penguins in the Arctic in winter. So the scattered penguins become this penguin roll, and it is still solid.

The inner and outer layers of neutron stars are degenerate states of neutrons, not quark-gluon plasma, because the temperature of supernova explosion is not enough to form. But some scientists believe that quarks exist in the universe.

The inner core of a neutron star is composed of hyperons, the middle layer is free neutrons, and the surface is used for neutron decay into electrons, protons and neutrinos.
