D)a type of radiation that we have detected so far only with infrared telescopes in space

Question

Quizplus · Accepted Answer

Hawking radiation is the gradual evaporation (and shrinking in mass) of black holes due to the emission of particles (including photons) from just outside the event horizon. This process was described by Stephen Hawking in the 1970s and is a consequence of quantum mechanics near the edge of a black hole.
