Yeah, I know about Hawking Radiation, but that's a natural and slow process, right?A.T. said:

I don't think that's a silly question at all! I suspect that the answer is no. But, the idea of some sort of stimulated evaporation is a lot more plausible than some of the really silly questions we get.elusiveshame said:Is there any other way that could happen by a man-made approach that would accelerate the evaporation?

That said, currently black holes are governed theoretically by GR, with the QM effect of Hawking radiation being something of an anomaly. If and when we have a theory of quantum gravity, then the possibilities for how a black hole behaves may change.
A black hole is not a mass-eating monster! The gravity of the black hole is the same as the collapsed star from which it formed - as long as you remain beyond the original surface radius of the star. I.e. if the Sun became a black hole, this would not directly affect the Earth's orbit. It's only if you get within the original suface radius that the gravity is greater - and once you reach the event horizon, then there is no going back.elusiveshame said:Would there be any benefit to speeding up that process (if it were possible and plausible to do so) aside from maybe preventing a head on collision with one, if one were detected to be heading towards us? When a BH evaporates, there's no point in which we'd be able to "see inside" of it because it'd still be shrouded by the event horizon, yeah? Or would it become "visible" once the mass reaches a certain level?
D'oh. I feel like I knew this, too. Thanks for the reminder :)PeroK said:A black hole is not a mass-eating monster!

In that sense, a black hole would be no more dangerous than a rogue star of the same mass. And, the danger of a rogue star is extremely low risk.
A black hole is a region in space where the gravitational pull is so strong that nothing, not even light, can escape from it. It is formed when a large star collapses under its own gravity.
According to current scientific understanding, nothing can reduce the size of a black hole. The only way for a black hole to decrease in size is through the process of Hawking radiation, which is an extremely slow and gradual process.
Hawking radiation is a theoretical process proposed by physicist Stephen Hawking. It suggests that black holes emit radiation over time, causing them to slowly lose mass and eventually evaporate.
No, a black hole cannot be destroyed. Even if it were to lose all of its mass through Hawking radiation, the singularity at the center would still exist. However, the event horizon, which marks the point of no return for objects entering the black hole, would no longer exist.
Based on our current understanding of physics, nothing can escape from a black hole once it has passed the event horizon. However, some theories suggest that there may be a way for information to escape from a black hole, but this is still a topic of ongoing research and debate.
