Ah, found the statement from Wald that I was trying to look up. I should have just quoted him instead. He is far more rigorous than me...

It appears to be paywalled, unfortunately. Yes, that makes sense. A damping term in the relativistic force equation would result in...

It's the standard one accepted by physicists who work on GR, and has been ever since the Bianchi identities satisfied by the EFE were...

More precisely: a photon emitted by a comoving observer and measured to have a certain energy at emission by that comoving observer...

If there's an example in the literature, I'd be interested in seeing it. Note that in GR, for example, spacetimes that do not have a...

No "energy" in the sense of Noether's Theorem; but local conservation of stress-energy still holds, since the EFE always holds in GR. So...

Yes. No, it doesn't, because in GR the local conservation of stress-energy is enforced by the Einstein Field Equation. So it's...

Has anyone ever proposed a consistent set of physical laws that has this property? I'm not aware of any.

In order to even try to answer what happens in such a scenario, you have to have some set of physical laws that you're going to apply...

No, that's not what he said. He said they are a two-particle excitation of a quantum field. That's not the same as a one-particle...

That's because QFT adds nothing useful to the treatment of entanglement, as far as making predictions goes, that's not already contained...

Because quantum fields are fundamentally non-local objects. Which many would say is not really an explanation, just a restatement of the...

Please do not venture into personal speculation.

Different QM interpretations give different (and incompatible) answers to this question.
