Is it possible that Black Holes are not simply extreme gravity, but the combination of all 4 forces?

A black hole is believed to be the collapsed remnants of an old star. Because the matter is crushed into a very small point, curvature is extreme. And extreme curvature coupled with very high mass causes a huge distortion in space-time, thus, an immense gravitational attraction.

Black holes do not follow electromagnetism. In fact, electromagnetic radiation cannot escape from a black hole at all. It is possible that, inside the black hole, there are electromagnetic forces at work, but because we cannot see inside the event horizon, there is no way to tell.

As for the nuclear and weak forces, it is quite unlikely, but not impossible. In neutron stars, matter is crushed together so densely that electrons combine with protons and form neutrons. In black holes, even more extreme circumstances could lead to the formation of different types of matter, which may not follow normal rules. There is no real way to tell.

While all 4 forces are at play, the primary force that results in the black holes is gravity due to the extreme mass.
