EBU or presentism, depending on the state of your mind.

Actually there is a way to have a block universe interpretation of quantum maechanics even with state reduction assumed. You just...

Well, J.L. Synge also considered them the same object in the presence of a metric; and only in the presence of a metric is the exact...

That only shows determinism, which is distinct from block universe. Newtonian physics is deterministic, but that didn’t force anyone to...

Wow, I love that!!!

There can be two topologically different manifolds with the same metric everywhere, neither of which is incomplete in any way. A pure...

Ok, so if I stretch a rubber band over 2 pegs, so it is stretched, you would claim you must consider that there is no force anywhere, as...

Definitely. If you define a force as that which is mediated by particle exchange, and treat gravity as a theory of gravitons, then all...

You may adopt that definition. But the definition accepted by most in this thread is whether it can be measured. Tidal effects and...

You can’t transform away tidal gravity. In every frame there some non EM force that the EM force resists until it can’t. Even more...

I think earlier it is mentioned that tidal gravity, the actual manifestation of curvature, is not fictitious. GW would similarly not be...

By removing the singularity, quantum gravity would have only geodesically complete slices and there would also be an apparent horizon...

This whole section responds to a (to me) surprising interpretation of what I wrote. If someone says "quantum theory converts the...

In the case of a black hole from collapse, I think it is legitimate to talk about mass (or stress energy, more broadly) matter being the...

It does for me.
