Bohmian mechanics v Everett-DeWiit-Wheeler? For Carroll, it probably means
they're the same. Indistinguishable. Ok, scratch that off the physics bucket
list.

In the February 3, 2025 issue of the journal Nature Sean Carroll wrote this
article. Here are a few interesting quotes:
"In the Everettian, or many-worlds, interpretation, introduced by Hugh Everett,
observers become entangled with the systems they measure, and every allowed
outcome is realized in separate branches of the wavefunction, which are
interpreted as parallel worlds."
"As far as anyone knows, there is no experiment that could distinguish between
pilot-wave and Everettian approaches. (Advocates of each tend to argue that the
other is simply ill defined.) So, physicists don’t agree on what precisely a
measurement is, whether wavefunctions represent physical reality, whether there
are physical variables in addition to the wavefunction or whether the
wavefunction always obeys the Schrödinger equation."
Why even physicists still don’t understand quantum theory 100 years on
