particle creation by black holes
In: 0
It’s an idea, so not confirmed by observations yet and the idea came up to explain black holes otherwise violating the laws of thermodynamics.
In simple terms it would be basically like this:
All the time “vacuum fluctuations” happen, where from nothing both a particle and it’s antiparticle are born, and immediately destroy each other again. Near black holes the gravity gradient is so steep that one of these particles gets pulled into the black hole while the other one is able to escape. Net particles are created, and the black hole “pays” for that by shrinking to keep the overall energy in the universe the same.

Black holes don’t create particles. What goes on is that you have virtual particle pairs created everywhere, just part of how quantum physics work. Given a bit of empty space, a particle and its antiparticle will spontaneously appear, travel for a bit, and then annihilate each other. Nothing gained, nothing lost.
How black holes get involved in that is the gravity near the event horizon is strong enough to occasionally pull one particle away from the other before they annihilate. The two particles now travel independently, and since matter/energy has been created, the black hole must shrink to balance.
