Hawking shows that black holes radiate

Applying quantum field theory to the curved spacetime around a horizon, Stephen Hawking found that a black hole emits a thermal spectrum at a temperature inversely proportional to its mass, and published the result in Nature under the title "Black hole explosions?". The calculation vindicated Bekenstein's entropy proposal and fixed its coefficient, and it made black holes objects that lose mass and can in principle disappear. For every known astrophysical black hole the predicted temperature is far below that of the cosmic microwave background, so the effect has never been observed.

Historical — it happened, and the record is settled.
