Theoretically, what would happen if Neutron Stars...?

Neutrons stars a phenomena due to the Pauli exclusion principal. Which states. No two fermions can occupy the same place at the same with the same quantum numbers.

This means that the neutron star has collapsed but due to that principal it cannot collapse any further. I'm afraid you answer would be somewhat dull. The core of the neutron star is purely neutrons. The outside is iron. Due to iron being the most stable element. if you were to strip this iron away and bombard it with charged particles. The electrons would hit the neutrons and but electron capture produce an anti-proton (and an electron neutrino, but that does diddly squat) the anti-proton would annihilate a neutron producing energy, so it would evaporate the neutron star.

Protons would probably just knock some neutrons out of the star (which would just fall back in due to immense gravity, and conservation of energy) their fate would probably be the same as the protons that were around before neutron star was a neutron star. Which would be to be crushed into a positron (which would be ejected) and a neutron.

i think of all and sundry may be fairly taken aback to locate a "rouge" action picture star everywhere, considering pinkish stars are fantastically unusual. on the different hand, if a "rogue" neutron action picture star only happened to bypass by our photograph voltaic device, we would possibly all be ineffective almost immediately after the earth's orbit became disrupted.
