A link between particle physics and gravity applies to Hawking radiation

Hawking radiation is the faint emission of particles from a black hole (illustrated). It’s too weak to be seen directly, so physicists are coming up with new ways of studying it theoretically.

Physicists have found a new way to investigate a long-standing black hole enigma using the mathematics of particle physics.

Black holes aren’t entirely black. They emit a faint mist of particles called Hawking radiation , a concept central to major puzzles that swirl around black holes.…
