Atoms, carbon, photons.. don't logically exist inside black holes or neutron stars.
Stars "collapse" or become neutron stars because neutrons are denser than protons in terms of both mass and energy per unit volume.
Neutron stars "collapse" or become black holes because black holes are denser than any neutron or neutron star.
Neutron stars are made of neutrons ... packed one against the other in what the egg-heads call "neutron degenerate matter" and this is given full "state-of-matter" status ... low volume, high gravity ...My question is whether these neutrons stars just keep getting bigger until it has enough mass to trap photons with its gravity ... creating an event horizon a.k.a. a black hole ... if so, then the Earth could exist, but she would collapse down to her neutron degenerate state ... and wouldn't be useful for biology ... looks like the Earth would experience a type 1a supernova event at some point, so life couldn't exist ... or maybe just sublime ...
Look, neutrons and protons weigh almost exactly the same within about 99.9%, they differ only in the arrangement of quarks inside, that 0.1% probably accounting for the positive charge of the proton (positive charges are typically due to a "hole" leaving a deficit, as well as the fact that these particles behave and exist differently in free space as opposed to when combined in an atom. To compound matters further, beta decay allows one to interchange to the other.
So, neutron stars degenerate as such simply because neutrons are the more degenerate and stable of the two particle states as a stable midpoint in stellar evolution from the main sequence to the degenerate core of a supermassive stellar explosion leaving behind the dead core of the star composited down to the most decayed state ordinary matter can withstand without collapsing into a black hole, not because one is slightly "heavier."
As to what "logically exists" inside a black hole, that is pure speculation since we cannot ever directly measure the crossing of an event horizon toward the singularity within, indeed, seen from our POV, such a crossing never happens, the event taking longer than the age of the universe!
