Could a black hole be destroyed from outside?

Question

For example, say that a relatively small black hole is in tight orbit around a massive star -- perhaps 30 solar masses. If the parent star goes supernova, would it be possible for the black hole to be destroyed?

If this scenario doesn't work, are there any that do?

Answer 1

well black holes are death stars and the only way for a black hole to get destroy is to be swallow by a greater black hole,,,

Answer 2

You could certainly have a black hole in orbit around a star, but if the star went supernova, the black hole would absorb the matter that came in its direction and would get bigger.

The only way a black hole can get smaller is by "evaporation" and this is a very slow process which takes millions of times the current age of the universe.

Answer 3

That is a great question. But I do not think it would happen. The density of a black hole would protect it from a super nova. But like a neutron star it would accredit mass from the star and if the material is outside of the limit I could see it as a possibility that the hole would have ring system.
Probably impossible, but it would be cool.

Answer 4

A black hole is not a planet, so it doesn't orbit around a star. And it can't be destroyed, but if it absorbs enough hydrogen it turns back into a star.

Answer 5

There is a theorem in General Relativity that says that whatever you do to a Black Hole, you cannot decrease its size. Basically, any energy you put in will only make it bigger, and there is no way to put in negative energy. The only thing that will decrease the size of a Black Hole is to allow Hawking radiation to radiate it away. This is a *very* slow process for a big hole.

Answer 6

I see what you're getting at, but it would take more than one star going nova, perhaps if a couple stars right near the black hole went nova at the same time. I have never heard of anyone trying to calculate this.

Answer 7

actualy no black holes orbit any thing a relitavly small black hole can destroy much larger stars there gravity will absord any thing a super nova could throw at it including the star its self

Answer 8

ok it will not
because of many reasons
well it is super dence and so will easilly swallow every thing coming to it
and if it is not able to eat that thing (it must be moving with more speed than light as light is also swallowed) then it will follow (it is mean and hungry)
and if you think super power of shocks will make it perrish then it is not logical too as it produces more frequently shock waves which have higher intencity than even of Pulsar's (the nutron star)
so i dont think it can be destroyed that way (from out side)

Answer 9

No, the black hole would simply absorb the matter. It would probably get more powerful. I think that the only way they die is by slow decay.

Answer 10

It doesn't seems to me because the of their gravitational force.
