What are black holes

A central law for black holes predicts that the total area of their event horizons – the boundary beyond which nothing can ever escape – should never shrink. This law is Hawking’s area theorem, named after physicist Stephen Hawking, who derived the theorem in 1971. Fifty years later, physicists at Cornell, MIT and elsewhere have confirmed ...

The black hole, named 3XMM J215022.4−055108, is indicated by the white circle.
