A black hole is a region of spacetime with an extremely strong gravitational pull.
The gravity is so strong that nothing, including light and other electromagnetic waves, can escape once it gets too close.
According to Einstein's theory of general relativity, a compact mass can warp spacetime to create a black hole.
The mass must be sufficiently compact to form a black hole.
