Are new discoveries in quantum physics (e.g. Amplituhedron, Higgs boson) supporting one of the classical QM interpretations? For example Copenhagen, Everett many worlds or Penrose interpretations. Or are these discoveries making new path for new interpretation/theory?

  • $\begingroup$ As far as I know, the only direction in which recent experiments push interpretations of quantum mechanics theory is that we now understand that wave function collapse is not all-or-nothing, and that collapse occurs over a finite amount of time. $\endgroup$ – DanielSank Sep 24 '15 at 17:48
  • $\begingroup$ @DanielSank in what sense? Certainly decoherence takes time, but the actual selection of one option out of the decohered possibilities is not usually considered a dynamical process. $\endgroup$ – Robert Mastragostino Sep 24 '15 at 17:49
  • $\begingroup$ @Radek : can you tell me more about this amplituhedron? Was that discovered at the LHC? $\endgroup$ – John Duffield Sep 24 '15 at 17:52
  • $\begingroup$ @RobertMastragostino I made a critical blunder in my comment. You're absolutely right. Established theory has a pure state turning into a mixed one (classical probability distribution) through interaction with other degrees of freedom. That's not the same thing as the observing human seeing realization of one of the possibilities in that distribution. That part is what I, personally, would call "the measurement problem" since it is very strange and somehow bizarrely inconsistent with the rest of the theory. $\endgroup$ – DanielSank Sep 24 '15 at 17:55
  • $\begingroup$ @JohnDuffield Yes I mean amplituhedron discovered in LHC. The question is if this or another discovery suggested what qm interpretation is right. $\endgroup$ – Ripe90 Sep 24 '15 at 18:23
