Hawking radiation is a theoretical type of thermal electromagnetic radiation that astrophysicists predict is emitted by quantum singularities (black holes). The theory was first posited by Professor Stephen Hawking and physicist Jacob Bekenstein who theorized that whenever stellar matter enters the event horizon (the boundary of a singularity where its gravitational pull becomes so strong nothing can escape, not even light) its interaction with the singularity's quantum/gravitational field would produce a unique type of radiation. Figuring out how to detect Hawking radiation would help locate singularities far more accurately than current methods; however as of 2018 no confirmed cases of Hawking radiation have been found out in interstellar space.
