Yeah, I don't really have many calculational questions arising from the musings as I am no longer being asked by homework assignments to...

Because of the ontological questions? If so, just pick the ontology you prefer. You are always free to change it later if your...

I cannot help you with philosophical questions like ontological status. Usually, you can adopt any ontology you like and simply adjust...

That seems closely analogous to me. In the case of work if you assume a piston then you can show the thermodynamic and mechanical work...

Of course it does. That is the whole point of writing the equations of motion and finding solutions. If you have a system of equations...

Well, this sort of thing is pretty common. Like for “work”. In Newtonian mechanics it is force times displacement. But in thermo it is...

I would wait until the final version is published. But I don’t think that it changes my answer.

A complete model in this universe, yes. The question was if an alternative universe without that feature is self consistent. And it...

That's correct. It's a consequence of the Einstein Field Equation, plus including all forms of local stress-energy in your model. In a...

That is the opposite of what I said above. The discussion that others were having is whether or not the FLRW spacetime is a counter...

Sorry about that. There doesn’t appear to be much in the way of later follow-up.

Here is a relativistic damped oscillator: https://www.jstor.org/stable/2098796 It was not constructed as I had thought, by adding an...

I’m sure I can google up a reference for a relativistic damped harmonic oscillator for you. I will try to do so tonight

Do you define GR to "obey relativity" (or do you read "obey relativity" as global Lorentz invariance)? Depending on the reading of the...

I would think that you could take a relativistic Lagrangian and just add an explicit symmetry violating term. That should be self...
