Sorry, but I wrote an answer to a post where something was written about a "spacetime geometry in which the hole can evaporate", and evaporation of BHs is certainly a trans-Planckian effect, thus, a hypothesis about quantum gravity. Where quantum gravity effects become relevant is something we...

It is worth to note that this is speculation. What is established science is semiclassical gravity. This is an approximation, where the gravitational field simply follows classical equations, and as the energy-momentum tensor of matter a classical approximation is used. One can be quite sure...

Certainly not. It is the price you pay for not caring enough about interpretations making sense at all. For those who want to preserve realism there is a large number of realist interpretations, starting with dBB and Nelsonian stochastics. Actually the best one is IMHO Caticha's entropic...

The formulas have been given, for simplicity, for scalar field theory, but it is said that the field ontology works for other bosonic fields too. But, ok, here is a paper which describes explicitly the EM field: Kaloyerou, P.N. (1994). The causal interpretation of the electromagnetic field...

Ok. That means, another proposal made by Bohm et al later is better, it does not have your problem: Bohm.D., Hiley, B.J., Kaloyerou, P.N. (1987). An ontological basis for the quantum theory, Phys. Reports 144(6), 321-375 Of course, for vector gauge fields the Wilsonian lattice variant is even...

In a field theory, the field beables are ##\phi(x)##. In the corresponding lattice model, the corresponding beables are ##\phi(n)## for ##n\in\mathbb{Z}^3_N\subset \mathbb{R}^3##. So it is simply a subset. There is also no problem with the momentum variables, which are in both cases simply...

No, it is a point charge in QM too. The configuration is defined by a single point position. And from the Schroedinger equation follows a continuity equation for the probability density in the configuration space, so to claim that there is no continuity is unjustified too.

Hm. You think the explanation given by standard QM is not sufficient? Why? If the QM explanation is fine, then the BM explanation is simple. One derives the QM rules in quantum equilibrium, and then applies the QM explanation.

In the usual realistic interpretations, the state of a system is described by its configuration space trajectory ##q(t) \in Q##. So, the same reality as in a classical Lagrange formalism. The wave function is in some of them also part of reality (dBB) in others it is epistemic (Caticha's...

In general, every deterministic theory can be obtained from a more fundamental stochastic theory, and every stochastic theory from a more fundamental deterministic one.

Why do you think that stochastic interpretations have some collapse? For example, Caticha's entropic dynamics has no physical collapse, the wave function has an epistemic interpretation. It has some sort of Brownian motion of what really exists - the configuration. What defines this...

This quote suggests that this would be Goldstein's position. If you look at the context, it is not. Spin measurement is contextual. And that means that the measurement result depends not only on the state of the system, but also on the state of the measurement device. If the result of an...

If one wants to quantize gravity and, given the situation with quantum nonlocality, wants to use a preferred frame, the first question is, of course, how to incorporate the preferred frame into GR. I would think there are two possibilities, either the preferred frame is local, or it is global...

Particles being something completely irrelevant, like phonons, the "particles of sound", is the other possibility. In this case, the fundamental thing is the field, and it cannot be created or destroyed. But because of the interaction with other fields, it can change its own part of energy...
