What is a black hole?
- A black hole is an astronomical body so compact that its gravity prevents anything, including light, from escaping.
- Albert Einstein's theory of general relativity, which describes gravitation as the curvature of spacetime, predicts that any sufficiently compact mass will form a black hole.
- The boundary of no escape is called the event horizon.

How this page was built
The question was read for its subject and its type. The subject was searched on en.wikipedia.org, the matching article was selected, and the sentences that answer the question were taken from it. Nothing was rewritten and nothing was invented; where the source does not answer, this page says so rather than filling the gap. The full method is here.
