Is a neutron star held together mainly by the strong force? Are they dense enough so that this is the case, or is gravity the only thing to consider? What about black holes?
It is called degeneracy pressure. Electron degeneracy pressure keeps a White Dwarf from collapsing further. Add more mass, and this pressure is "overwhelmed" by gravity and it could collapse to a Neutron star. Then, we have neutron degeneracy pressure. Add more mass and we can collapse to a black hole.Jonny_trigonometry said:I just don't see why it would prevent gravity from pulling everything together too much. If it acted in a way as to repel each neutron from the others, then it would prevent gravity from pulling them closer than 10^-15 meters apart, so that if matter was constantly being put into the system, the whole star would have a maximum density for a while until the strong force couldn't repel things enough to overcome gravity and the core would collapse. But this is not how it works as far as i understand.
