GENERAL KNOWLEDGE

Detailed explanation-1: -In General Relativity gravity is not a force, because it is spacetime curvature. All proponents of the black hole assert that all their black holes have a finite (non-zero) mass. This mass they say is concentrated in the black hole’s ‘singularity’ where density is infinite and spacetime curvature is infinite.

Detailed explanation-2: -If enough mass is concentrated in a small enough region of spacetime, the spacetime curvature can become infinite. The pull of gravity in this case becomes so strong that nothing, not even light, can escape this region.

Detailed explanation-3: -A “gravitational singularity” sits at the center of a black hole. This is a point where the curvature of spacetime is infinite (I know, it’s hard to comprehend).

Detailed explanation-4: -In short, black holes are massive pits of gravity that bend space-time because of their incredibly dense centers, or singularities.. When a star dies, it collapses inward rapidly. As it collapses, the star explodes into a supernova-a catastrophic expulsion of its outer material.

Detailed explanation-5: -The infinite nature of singularities means that space and time as we know them cease to exist there. Scientists have long sought ways to avoid the complete breakdown of all the known laws of physics brought on by singularities.
