Detailed explanation-1: -A black hole is an astronomical object with a gravitational pull so strong that nothing, not even light, can escape it. A black hole’s “surface, ‘’ called its event horizon, defines the boundary where the velocity needed to escape exceeds the speed of light, which is the speed limit of the cosmos.
Detailed explanation-2: -A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.
Detailed explanation-3: -The black hole has greater pull. If you stand beside a massive object (planet, star, black hole or anything else with mass) you will feel a gravitational pull, and unless you do something about it you will start to accelerate towards the object.
