What is the term for the boundary beyond which nothing, including light, can escape a black hole?
Answer
Event horizon
A black hole is defined by the event horizon, which is the boundary within spacetime past which escape becomes impossible, meaning nothing, including electromagnetic radiation like light, can get out.
