There are but it is pretty massive and close regardless. Biggest is a weird word for a black hole btw since they are infinitely small

They're represented as a singularity, and for all all intents and purposes it's a good approximation because the event horizon is always larger than the radius, but they do have a diameter. They form when the opposing forces between adjacent electrons and protons is overcome by the gravitational force, but the subatomic particles didn't go anywhere, they're just stacked on top of each other rreeeaaallll tight

This is the basis for electron degeneracy in neutron stars due to the Paul exclusion principle. Black holes on the other hand aren't composed of fermions, as the singularity is more like knotted space or a closed timelike curve. They can be defined as having three foundational characteristics: charge, spin, and mass.

You know, you're right, I do remember that being about stars now. Thanks for the little lesson, my astrophysics course never got quite that deep :)
