The discussion revolves around Sean Carroll's podcast on the many worlds interpretation of quantum mechanics, exploring various perspectives on his views and the implications of his recent book. Participants express their thoughts on the interpretation of quantum mechanics, the role of science communication, and the public understanding of complex scientific concepts.
Participants do not reach a consensus; there are competing views regarding the validity of Carroll's interpretations and the appropriateness of his communication strategies. Concerns about the potential for misinformation and the responsibilities of scientists in public outreach are also debated.
Participants express limitations in their ability to assess the content of Carroll's book without having read it, leading to uncertainty about the claims made in public discussions. The discussion reflects ongoing debates within the community about the nature of quantum mechanics and its interpretations.
Local means the relativistic Lagrangian dynamics are just functions of X and not X, Y etc. QFT fulfils this requirement and as that is all there is to MWI, MWI is local. No non-local FTL collapse.PeterDonis said:That depends on what you mean by "local" and "realist". Measurements having multiple outcomes violates many people's definition of "realist". And having wave functions that entangle spatially separated systems violates at least some people's definition of "local".
