    Undergrad Does causality become relative in spacelike-separated entanglement measurements?

    FWIW, I tend to subscribe to Art Hobson's view (although, as I understand it there are details to be worked out): Quantum Fields are nonlocal (and, apparently, not subject to the limits of GR). It is pretty amazing. Local hidden variables seem to have been ruled out and Many Worlds is simply...

    Undergrad Does causality become relative in spacelike-separated entanglement measurements?

    If it is okay, I would like to start this topic in the interpretation subforum to read the comments of the board members. Also, while I am at it, thank you for this board. I feel fortunate to be able to "peek in" at physicists really working out (through experiments, etc.) how physics works...

    Undergrad Does causality become relative in spacelike-separated entanglement measurements?

    I found this thread when I was considering whether there is something more than correlations to entangled particles. I think we know when we measure/detect the spin of a local particle, we then immediately know what the spin will be of the nonlocal (e.g., a galaxy away!) entangled particle. We...

    Undergrad Particle vs Wave Interpretations of QM

    A fundamental "particle" is an excitation in its quantum field. An excitation in a quantum field is energy. I don't think you can blame "pop sci" (although I think you can potentially blame "pop sci" for elevating the role of consciousness in quantum theory). 99% of baryon mass is the result...

    Undergrad Are classical optics and quantum mechanics double slit experiments fundamentally the same?

    From what I know, I would view it as "energy" in the photon field that has not sufficiently excited the field (locally?) to generate the photon. (Keeping head down because probably not using proper terminology)(I'm a "layperson").

    Undergrad Particle vs Wave Interpretations of QM

    FWIW, this seems right to me. It seems to me the term "information" is another anthromorphic term (like "observer" and even "measurement") that causes confusion. Everything seems to come down to a question of how "energy" is organized. (I might get a wrap on the knuckle for this comment too).

    Undergrad Particle vs Wave Interpretations of QM

    For what its worth, Art Hobson states, in Fields and Their Quanta, "The universe is a set of at least 25 fields, each of which fills the entire universe. These fields are probably facets of a single universal field." (P. 183)

    Undergrad Carroll interviews Barandes on Indivisible Stochastic QM

    Does it matter that the notion of retrocausality initially attributed to the "delayed choice" experiment has largely been debunked: It looks like the explanation of this fits well within Art Hobson's model.

    Undergrad Carroll interviews Barandes on Indivisible Stochastic QM

    Here is a summary of Art Hobson's view in Wigner's friend (hope okay to post--feel fee to ignore): Physicists like Art Hobson view the Wigner’s friend paradox and the idea of "superposed memories" as a misunderstanding of how quantum mechanics actually works. Hobson, a staunch proponent of...

    Undergrad Particle vs Wave Interpretations of QM

    My impression: He highlights that the pre-detection state is non-local. He stresses repeatedly that failure to accept this historically has pushed the physics community in wrong directions. He references the Rarity-Tapster-Ou (RTO) Experiments (and of course Bell's and Anspect's work). In...

    Undergrad Particle vs Wave Interpretations of QM

    At some point I would like to start (or participate in) a thread dedicated to Art Hobson's views in Fields and their Quanta and his other writings (strengths/weaknesses). At one point he "seems" to assert there is a causal relationship between entangled particles (even millions of miles apart)...

    Undergrad Particle vs Wave Interpretations of QM

    I am sorry I interfered with the more detailed discussion you are having. At some point (after your technical discussion is concluded) I would love a better understanding of this point (the more conceptual and less mathematical, the better) The you that is in the "cat is alive" branch sees the...

    Undergrad Particle vs Wave Interpretations of QM

    I am trying to understand where, from just a plausibility perspective, I would deviate from MWI. So, I think this is it, but I want to make sure. So, Peter, even under a less extreme view of MWI, whenever a person looks at a detector showing the location of decohered photon (what other...

    Undergrad Particle vs Wave Interpretations of QM

    I have been trying to get a better understanding of what appears to be (to me) a less fantastical interpretation of the Many Worlds Interpretation (without gazillions of universes created every time a photon interacts with something, etc.). So, it seems the Relative State interpretation of MW...
