AI Thread Summary
A charged black hole orbiting a planet may radiate similarly to an object with the same mass and charge, particularly at sufficient distances from the planet. The discussion highlights that point charges do not radiate due to gravitational acceleration, raising questions about the behavior of charged black holes. While the radiation from such a black hole exists, its frequency and intensity are not particularly significant compared to other scenarios, like an electron orbiting a nucleus. The conversation emphasizes the need to consider these factors when discussing radiation from charged black holes. Overall, the radiation characteristics of a charged black hole are complex but can be compared to other charged objects.

If I had a charged black hole and it was orbiting a planet, would it radiate just like a point charge?

I don't think point charges radiate due to acceleration by gravity.
 
isn't that what everyone was worried about until quantum theory. about why the electron doesn't just radiate away its energy and fall into the nucleus.

It might be better to say "just like an object with the same mass and electric charge and that's not a black hole". If that's what you mean, then the answer is "yes, at least at sufficient distances from the planet and its charged satellite".

With that said, you might want to take a moment to consider the frequency and the intensity of that radiation... It's not very exciting stuff, at least not compared with an electron "orbiting" a nucleus.
 
it seems like the black hole would also radiate
