B What If Universes Were Made of Antimatter?

[Quarker]

Also assuming the two universes were made of the antimatter versions of themselves

What do you mean by "a mirror universe"?

 

[Ibix]

If you just mean "a universe in which the proportions of matter and antimatter are reversed with respect to this universe but the laws of physics are otherwise the same" then black holes would be no different.

Note that this answer is conditional on the assumption that you can just reverse the proportions of matter and antimatter. We don't know why they are what they are, so we don't know if you can have a universe with different proportions or not.

Assuming otherwise identical but mirror image, antimatter universes. If you could only observe the properties of one of the black holes, could you tell which universe you were in?

You still haven't said what you mean by "mirror". Do you just mean a universe with swapped amounts of matter and antimatter? Or something else?

Assume a two sided quantum field, so that every action in one universe has an equal but antimatter equivalent in the other, but they are divided by a quantum wall, so to speak. If you were observing a black hole in only one of the universes, is there a property it would have that would tell you which universe you were in?

Can you provide a reference where I can read about a "two sided quantum field"?

No, it’s hypothetical. That’s why I started the post with the word assuming.

So you've asked me to imagine something you made up, that doesn't have any mathematical model backing it.

That's like me asking you for details of the lifecycle of a glerk. What's a glerk? Well, I've just made it up and there's nothing but the name and an implication that it's a lifeform of some kind. How is anyone supposed to answer a question like that?

So what. It’s the properties of the black holes I’m wondering about. If you don’t know, feel free to say so.
