In theory, what would happen if anti-matter enters a black hole?

Question

Especially if a huge amount did. ( Which, I guess would be unlikely ).. Also, what if dark matter did?

Thanks!

Wouldn't the annihilation that occurs with matter and anti-matter combine, cause a reduction of the gravitational pull that the black hole exhibits? I mean, I'm talking a huge amount of anti-matter. I know it's playing what if's.. sorry. But say, a black hole came into contact with an almost equivalent amount of anti-matter of the original sun that turned into a black hole in the first place.

Answer 1

Antimatter still has positive mass. The properties of a black hole are confined to mass, spin, and charge. It would simply add to the mass of the black hole. Even if it annihilated with matter on the way in, the mass-energy would still add to the black hole's mass. Wiki "no hair theorem"

Answer 2

Antimatter enters a black hole all the time, though pair creation and what is known as Hawking radiation.
Since antimatter is just the same as regular matter, except with a reversed electrical charge, the black hole will behave the same was as if it was normal matter falling in, no difference could be perceived from an outside observer's perspective.

As far as dark matter is concerned, I am not sure if the theory of dark matter is advanced enough to tell if it should fall in a black hole at all.

Answer 3

I am thinking that a black hole is essentially " Gravity Gone Wild"
On a simpler scale, we could say that an electron and proton are somewhat similiar. Gravity behaves on each of these oppositely charged properties wihout any reversing effect, for example. So I am sure if we were able to increase the gravity on these particles that gravity would still behave the same on each of them. Therefore, I would expect the black hole to opperate the same on both forms of matter.

Answer 4

Speculatively:from anti-matter the black hole would come to an end, from dark matter it would turn more black.

Answer 5

Nothing the force is so great that nothing can escape.
