Then why do you keep bringing up elementary particles? Ballentine? I've read it completely, multiple times. Sure, Ballentine advocates...

Can you give an example of what you mean by this?

Pretty much, yes, although they are expressing it in global comoving coordinates instead of local inertial coordinates, and they haven't...

This is a fundamental point. It is clear by inspection the t coordinate is spacelike, not timelike inside the bubble when it is...

So you are summing the separate local observations of many (infinite) local inertial observers, each at a different cosmological time...

If the scenario is such that you can consider the molecule as a "particle", it has some nonzero probability to tunnel through a barrier...

And what, specifically, do you mean by "the path travelled by light"? Think carefully. In a curved spacetime, particularly one that is...

Because if the particles are bound inside a large object, they're not free particles, and all the stuff you refer to about tunneling and...

if you mean the coordinate speed of light, that doesn't even have to be ##c## in flat spacetime, if you use non-inertial coordinates...

There is no entanglement in the double-slit experiment, at least not in the most common version that's discussed, in which you can run...

Under appropriate circumstances, yes. "Appropriate circumstances", when you dig into the details, turns out to mean flat spacetime...

That depends on the specific scenario. In some cases you can describe a single elementary particle with a specific wave function and...

Perhaps, but there also has to be human stupidity, to allow an AI tool unsupervised write access to your database in the first place.

To amplify a bit on my earlier "I don't either" response: the "physical mechanism" the paper is investigating is decoherence, on a very...

If you consider glaring misstatements to be "of interest", I found one: "...the "Lindblad master equation," overcoming the limitations...
