black holes
Gravity's ultimate traps
A black hole is a region of space where gravity is so intense that nothing—including light—can escape.
Black holes form when massive stars collapse at the end of their lives, compressing matter into an infinitely dense point.
The boundary beyond which escape becomes impossible is the event horizon.
Figuratively, a black hole is anything that consumes resources without return: That project became a black hole for our budget.
