There is no "hidden variable" in MWI, it is not a hidden (or extra) variable theory. All there is is Schroedinger evolution of the...

No, this is not correct for Bohmian mechanics. In Bohmian mechanics, outcome information is contained in the unobservable particle...

Ah gotcha. I don't know this field that well, I was simply parroting back the article:

https://www.edmundoptics.com/knowledge-center/application-notes/lasers/gaussian-beam-propagation/?hl=en-US I am no expert in laser...

The premise of the thought experiment is that "alive" and "dead" are two distinct, macroscopically distinguishable cat states, and that...

In the general case, no, because not all observables have a discrete spectrum, and at least on its face, the math for observables with a...

Indeed: Thanks Bill

We would generally regard QFT as only an effective field theory that approximates some deeper theory as well. QFT still suffers from a...

Gleason's Theorem doesn't depend on any particular interpretation of QM: it just says that, given the basic math of QM, if you want to...

Although I agree with the general gist of statements made in this post (my read: decoherence drives branching, we don't branch off of...

I feel he had a nice idea -- gravity causes collapse. He put out some heuristics on how to look for it. The experimental community...

Fwiw, Sean Carroll, a quite strong proponent of MWI, says that "the probability problem" (all outcomes happen, so what do we really mean...

Nice, it looks like they are attempting to test the theory. But it does seem like maybe the most simple version of the theory has been...

There are also objective collapse theories (GRW, Penrose gravity-collapse) where the wave function collapse happens at dynamical...

This discussion felt a lot more substantive than the discussion with Maudlin, largely because a higher level of familiarity with the...
