I probably need Devac to vet and/or refute the first paragraph, especially. If he wants to, of course.

I'm gonna level with you here: this is far out my zone. Currently reading through this article and sources/followups to get more up to speed, but doubt you'll get much from me. The topic itself is kinda like solving Riemann's conjecture -- I obviously tried, but don't really have an opinion or profound (for a mathematician, at least) grasp of implications?

As far as I see it, the real problem is that, as with Bohmian mechanics and many similar hidden-variable theories, we can absolutely postulate it as valid but decisively testable only under the assumption we can achieve an infinitely-precise time resolution of the measurement... which we obviously can't do so the topic itself is moot at best, faff at worst. Especially in a world with better, more general and easier-to-use theories.

And yeah, if I didn’t have a physics background, I'm not sure how much I would get out of the PBS Space Time channel.

Dunno, but it introduces you to related vocab and concepts (or even points to a discipline, which is not always a trivial thing to determine), often accompanied with some intuitive animation/diagram, which alone honesty kicks the everloving shit out of many popsci books, picture being worth a thousand words and all that.
