Hawking radiation: a theoretical prediction

AI-generated conceptual black-hole image; not an observation of Hawking radiation.

NASA Goddard artist’s concept of hypothetical primordial black holes. NASA explicitly describes this as a fanciful concept and notes that the accretion disks shown are not realistic for such tiny black holes; it does not depict detected Hawking radiation. https://svs.gsfc.nasa.gov/14524/

Listen to fact0:00 / —

Quantum theory in curved spacetime predicts that black holes emit energy, a process called Hawking radiation. As a black hole loses energy, it also loses mass, but for ordinary astrophysical black holes the process should be extraordinarily slow. This radiation has not yet been directly detected from a real astrophysical black hole.
