You are describing what we call a "black hole'. It was actually predicted in the theory of relativity. Formulated by Albert Einstein in 1905, the theory of relativity is the notion that the laws of physics are the same everywhere. The theory explains the behavior of objects in space and time, and it was used to predict everything from the existence of black holes, to light bending due to gravity, to the behavior of the planet Mercury in its orbit.
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.
A black hole is an object with such strong gravity that not even light can escape its pull. This intense gravity is due to its extreme density, formed when a massive star collapses in on itself.
A black hole is created when a massive star collapses under its own gravity, causing its core to condense into a point of infinite density called a singularity. This creates a region of spacetime where gravity is so strong that nothing, not even light, can escape its pull.
Black holes are regions in space where gravity is so strong that nothing, not even light, can escape from them. They are formed when massive stars collapse under their own gravity.
A black hole is so dense that nothing, not even light, can escape its gravitational pull. It forms when a massive star collapses under its own gravity, creating a region where the gravitational force is so strong that not even light can escape from it.
A "Singularity" or a "black hole".
A black hole is an object so massive that light cannot escape its gravity, due to the intense gravitational pull caused by its mass and density.
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.
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.
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.
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.
