A black hole
Your category is the answer, that thing is black hole
A black hole has so much mass that light can't escape from it once it passes the event horizon. It can still escape if it hasn't passed the evnt horizon.
Yes, black holes are so massive and dense that their gravity is immensely strong. This gravity is often strong enough to prevent even light from escaping, which is why black holes are known as "black" because they do not emit any visible light.
Light is affected by gravity, if the gravity is immense. In a black hole, the gravity is so immense that light cannot escape from it, hence it cannot be seen - whcih is why it's called a "black hole".
A black hole is a region of space in which gravitation is so strong that not even light can escape found at the centers of galaxies and also as the final stage after the death of very massive stars.
A "Singularity" or a "black hole".
A black hole because it can be small and massive and not even light can escape it.
A black hole.
A black hole because it can be small and massive and not even light can escape it.
A black hole is formed when the remains of a massive star collapse under their own gravity, creating a region of spacetime where gravity is so strong that not even light can escape. The mass is concentrated into a small volume called the singularity at the center of the black hole, surrounded by an event horizon beyond which nothing can escape.
The atmosphere is held in place by gravity. Other things being equal, the more massive the planet, the harder it is for a gas molecule to escape into space.

No, a black hole is not some sifi mysterious thing that causes unknown things to occur, like complete realities. It is simply a massive source of gravity, so massive that light cannot escape it.

A black hole is an area where gravity is so strong that not even light can escape from it. This happens when a massive star collapses in on itself, creating a region of spacetime with an intense gravitational pull.
