Albert makes an interesting argument against Everettian QM, i.e. that repeated experiments will not produce statistics that converge to the Born rule, i.e. there will necessarily (not just probabilistically) be experimenters in worlds supporting every possible probability value. Brent On 9/3/

This sort of way of approaching physics is no different really from theological debates about some esoteric Christian doctrine. The last of Carroll's The Biggest Ideas in the Universe series is actually interesting at the end: https://www.youtube.com/watch?v=ZqphkIO7yt4 He has nowhere to g

I don't understand Albert's position or the distinction he is trying to make.

An interesting discussion of Everettian QM in two parts. The first part https://www.youtube.com/watch?v=FyvgBe9VV70 is just David Albert and Sean Carroll. It's quite reminiscent of JKC and Bruno, using the same thought experiments (but more civil). Brent -- You received this message becaus
