explain how a blackhole forms.
user
a black hole is created when a very massive star runs out of nuclear fuel and its core can no longer resist the stellar gravity. the core collapses inward in a chain reaction that rebounds outward, pushing the outer layers of the star into space in a supernova explosion. eventually, the core stops collapsing, compressing into a single point of an infinitely small radius and infinitely great density, known as a singularity. this creates an extremely powerful gravitational field which nothing, not even light, can escape, giving rise to its distinctive dark silhouette.
