Black hole, any region of space time where escape to the outside universe is impossible
Black dwarf, a type of degenerate dwarf star, specifically, a cold white dwarf.
A dark star is a theoretical object that obeys the laws of Newtonian mechanics, and has a surface escape velocity that equals or exceeds the speed of light. ... A black hole is an object predicted by general relativity,[1] with a gravitational field so powerful that even electromagnetic radiation (such as light) cannot escape its pull. ... A black dwarf is a hypothetical astronomical object: a white dwarf so old that it has cooled down so that it no longer emits significant heat or light. ...

Supermassive fl holes containing millions to billions of solar masses could also form wherever a large number of stars are packed in a relatively small region of space, or by large amounts of mass falling into a "seed" fl hole, or by repeated fusion of smaller fl holes.
Black holes require the general relativistic concept of a curved spacetime: their most striking properties rely on a distortion of the geometry of the space surrounding them.
Using the first law of fl hole mechanics, it follows that the entropy of a fl hole is one quarter of the area of the horizon.
The event horizon is the point outside the fl hole where the gravitational attraction becomes so strong that the escape velocity (the velocity at which an object would have to go to escape the gravitational field) equals the speed of light.
In fact, the theoretical prediction of fl holes is due to the General Theory of Relativity, which is built on the principle that the speed of light in a vacuum is constant.
Any star shines and survives because the pull of gravity, which is trying to compress it, just balances the pressure generated by the nuclear furnace at its centre, which is trying to expand it.
