Reply to comment by Bokbreath in TIL black holes also regurgitate matter such as stars that they suck in by Desolecontra
The article suggest that the particles are being ejected away from the black hole. What force cause the particles to drive away from the black hole and not into it? Is it reacting off the anti particle?
Can spontaneous particle creation be replicated using tech?

Yes they can be created spontaneously .. but only for very brief periods while the universe isn't paying attention. Then they recombine and the ledger is balanced. What is possible near the event horizon, is the anti-particle can cross the event horizon leaving the normal particle outside. It can escape (it also might not, but it can). If it does then the books still balance because the anti-particle robs the black hole of the exact mass of the particle.
Not sure what you mean by 'force applied away from the black hole'.

That's still pretty fascinating. Can particles just spontaneously appear out of nowhere? Do they exist just outside the event horizon for years. Why is the force applied away from the black hole and not towards it?

Nothing can escape the event horizon by definition. Not even light. That means anything being ejected from the vicinity of a black hole hasn't yet passed the event horizon.
This includes hawking radiation btw. That does not come from beyond the event horizon either. It happens when a particle/anti-particle pair is spontaneously created just outside the event horizon and before they can recombine, the anti-particle falls into the black hole and the particle escapes.
EDIT: someone correct me here plz. I'm getting flashbacks that the pair creation thing is different from hawking radiation but I don't know enough to be sure.

How did you determine the star was not devoured?

I'm not sure which journal, so attached the ASCA link. In fitness coaching they discussed the nervous system and the predispositions to be a better sprinter vs marathoner. Breath training plays a large part in developing athletes too re sympathetic and parasympathetic control. https://www.strengthandconditioning.org/journal

He should have charged then ten cents for him to pencil in a beard.

This is a terribly written article. The black hole has not 'devoured' the star. It hasn't crossed the event horizon. Best you could say is it's on the spoon making airplane noises on the way to being devoured.
