Can We Make Contact with an Anti-Matter Black Hole?

[chasrob]

Is there any such thing? Or is it unphysical?

If it's physical, would making contact with a matter black hole result in E=mc^2?

Thanks.

It's highly unlikely. In case of contact with matter (black hole or not), the reaction would take place inside, so we would never know.

Seems unphysical in this universe. not enough loose antimatter to go around.

But in an anti matter universe, perhaps so.

wiki answers sez:

What is an antimatter black hole?
Answer:

This is a black hole formed from antimatter, instead of matter. The only real difference thereby being that the matter within the black hole would have an opposite charge from normal matter. Other than that, an antimatter black hole, while still theoretical at this point, should have properties the same as a black hole formed from 'normal' matter.
As with a normal black hole, an antimatter black hole would be created by having enough antimatter to cause a gravitational collapse.

If an antimatter and a matter black hole collided, how much energy would be released?? Would it be enough to eject the gamma rays from the gravitational well?

You would never have an anti matter BH in a matter dominant universe. So the two would never collide.
An anti-matter BH could only form in a theoretical anti-matter universe.
google baryogenesis for more info.

Say a solar mass BH and antiBH were involved... several FOEs of energy released, and we see nothing? Wow, hard to believe.

Let's drop the answer that there isn't antimatter in high enough concentrations to produce black holes in our universe. That's irrelevant.

Once you've formed the black hole, it has exactly three properties: Mass, charge, and spin. Whether you make it out of matter, antimatter, or unicorns, these three numbers completely describe it. So you can make a BH of antimatter and one of matter with the same mass, charge and spin and they will be IDENTICAL.

If two collide, they will do what black holes do and merge into one larger black hole. I repeat, once you've formed the black hole it's just a black hole -- no special properties besides mass, charge, and spin remain.

The properties of matter will be crushed out of existence in a black hole, so they will not be distinguishable one from the other. In other words, I agree with Nabeshin.

Yep, that's how it works, as far as anyone knows. In the current political climate it's difficult to acquire funds for the experiment.
