In theory it is compressed down into a singularity. This is why black holes are the densest objects in the universe. All that mass is being squeezed down into a single point in space.
A planet that falls into a black hole would get completely destroyed. Its mass would be added to the mass of the black hole.
Black Holes eat everything including light. No matter how fast your going, nor how much mass you have. If you cross the event horizon, "The point of no return", then you are going to get sucked in.
Dead stars are not necessarily black holes. Dead stars can become white dwarfs, neutron stars, or black holes depending on their mass. Only the most massive dead stars can collapse further to become black holes if they exceed the Chandrasekhar limit, around 1.4 times the mass of the Sun.
Black holes.
Probably stellar mass black holes
The relevant magnitude is mainly the black holes' mass. Since black holes are the result of collapsing stars, yes, there are black holes with the mass of a star.The diameter is usually taken as the diameter of the event horizon. This diameter is directly proportional to the mass; a supermassive black hole such as Sag A* has a diameter comparable to that of a large star.
it's mass
No, black holes are not infinite in size and mass. They have a finite size and mass, but their density is extremely high, leading to their strong gravitational pull.
Most black holes are stellar mass black holes with masses comparable to those of large stars as they form from the collapse of massive stars. Scientists know of the existence of supermassive black holes that are millions to billions of times the mass of our sun and can be found in the centers of most galaxies. Scientists still do not know how these black holes become so massive.
The most massive stars will die as black holes.
No. Without matter there would be no black hole. The black holes confirmed to exist so far actually have a fairly large amount of matter (or mass) - at least 2-3 times the mass of our Sun. The largest black holes have millions or even billions of times the mass of our Sun.No. Without matter there would be no black hole.

Yes. Intermediate-mass blackhole is a medium size black hole. Scientists have found stellar black holes and supermassive black holes but there is no prove that Intermediate-mass black type of black holes exist. My opinion is that they do exist because when a black hole is becoming a black hole supermassiveblack hole it will need to go though this stage of intermediate-mass black hole.
