Yes. You have one light beam coming from a source, which is split by a beam splitter, and then you have two detectors, and you look for...

It would help if you would give specific references for where you read or were told these things.

A single Stern-Gerlach experiment is not a "correlation experiment". To do a correlation experiment with Stern-Gerlach devices, you need...

The structure would have to be narrow enough for the variation in ##r## for a transverse beam to be negligible. Otherwise its proper...

No, that's not the claim that was made. Here's the claim that was made: The beam is supposed to be held static against gravity in...

I hadn't looked at it in detail because I was focusing on the first part and wanting to understand it. Having now looked at it, I'm not...

You don't seem to understand that the proper acceleration is determined by the beam's worldline. You can't adjust it by applying...

It occurred to me after posting #116 that by "local density" you might have meant something more like "local proper number density of...

I'm not sure you can do that. If you build the object in flat spacetime in an unstressed state, and then move it to hovering statically...

Depends on what you're trying to show. What I was trying to show is that I can take a rod built in flat spacetime with proper length...

Nothing that I said depends on the material model. The details of exactly what stresses will be present for an object described by a...

But it doesn't seem to me that there is any preferred basis of configurations. Surely, Barandes formulation doesn't stop you from...

Here, I'll even give a simple example for you to address the issue with. I build a rod in flat spacetime, in free fall. It has proper...

It's not an argument, it's a definition of what proper acceleration is and what it means physically. You can't say that all of the...

As I said, every QM interpretation has features that are unpalatable. It's just a question of what kinds of unpalatability you prefer to...
