Where is this from? Would like to see the context on this.

Yes, that's correct. A question was asked about global causal structure and black holes. That's relevant to the QFT viewpoint on...

Yes, you are wrong. The Kerr-Newman family of black hole spacetimes are globally hyperbolic. That means they have a well-posed initial...

Sort of. Many Worlds still has the problem of explaining why we observe the particular Bell inequality violating correlations that we...

Slight caveat here as it depends on your region of interest. As I understand it, the inner horizon ##r_-## forms a Cauchy horizon so...

There aren't any, at least not with the usual definition of "black hole". An asymptotically flat spacetime can only have one region that...

Got it, thanks! I'll take a deeper read of 12.3. I skimmed through it earlier.

More precisely, they encompass all vacuum (actually electrovacuum, see below) black hole solutions. The Vaidya metric was mentioned...

Right... I'm not talking about scalar invariants or singularities in my latest question. I understand the scalar invariants in...

I meant my question for the statement "which AFAIK is all black hole solutions."

(Genuine question) Is this a consequence of the No Hair Theorem?

I realize this is a popular science level answer and focusing on the Schwarzschild solution is totally fine. But just pointing out for...

You can certainly debate anything, but SR is generally formulated on the constancy of the speed of light and the equal validity of all...

True statement. I did not mean to imply the opposite.
