What exotic substance primarily composes a Neutron Star?
Answer
Neutrons packed tightly together.
A neutron star represents a state of matter so dense that the protons and electrons have been forced together by immense gravitational pressure, combining to form neutrons. These objects are fundamentally composed almost entirely of neutrons densely packed against one another. This composition allows the star to achieve an astonishing density, compressing the mass equivalent of one or two Suns into a sphere roughly the size of a city. This structure is held up against further gravitational collapse by the degeneracy pressure exerted by these closely packed neutrons.
