Detailed explanation-1: -Well, even though black holes are extreme in many ways, they don’t have infinite mass-and it’s mass that determines the force of their gravity. Some black holes-known as stellar black holes.-have about the amount of mass that very massive stars do.
Detailed explanation-2: -The density at the center of a black hole is infinite (it’s a famous “singularity", which leads to difficulties in modern cosmology).
Detailed explanation-3: -A black hole is an extremely massive concentration of matter, created when the largest stars collapse at the end of their lives. Astronomers theorize that a point with infinite density-called a singularity-lies at the center of black holes.
Detailed explanation-4: -A black hole has an infinite density; since its volume is zero, it is compressed to the very limit.
Detailed explanation-5: -NASA scientists have identified the lightest black hole yet, just 3.8 times the mass of the sun, in a binary star system in the Milky Way known as XTE J1650-500.
