A black hole is a region of space where the gravitational pull is so strong that nothing, not even light, can escape from it. They are formed when massive stars collapse at the end of their life cycle.
Formation of Black Holes
When a massive star exhausts its nuclear fuel, it can no longer support its own mass, leading to a catastrophic collapse. This collapse results in the formation of a black hole.
Characteristics of Black Holes
Event Horizon: This is the boundary around a black hole beyond which nothing can escape its gravitational pull.
Singularity: At the center of a black hole lies a point of infinite density and gravity, known as a singularity.
Spaghettification: Near a black hole, the gravitational pull is so strong that it can stretch objects into long, thin shapes in a process called spaghettification.
