blackholes

Gravity's ultimate traps

Black holes are regions in space where gravity is so intense that nothing—not even light—can escape.

They form when massive stars collapse.

The term extends figuratively to anything that consumes resources without return: That project became a black hole for the budget.

Usually spelled as two words: black hole.
