In cores of more than 3 solar masses, gravity completely overcomes any outward pressure from the core's compressed material. In theory, the core contracts into a point of zero volume but infinite density, called a singularity. The gravitational field of Black hole the singularity is so intense that it creates a region of space called a black hole around the singularity: once DETECTING A BLACK HOLE inside a black hole, nothing, not even Gases streaming toward a black hole light, can get out. reach speeds approaching the speed of light. They are heated by friction, which causes them to give off detectable X-rays. PRIME FACT SUSPECTS FILE
