Thanks. As (I think) David Kaplan said in the movie, it's a "f***ing cool" time to be alive if your interested in physics. For the purposes of this thread I'm specifically interested in whether the MV "opposes" supersymmetry in some sense. I suspect that the difference has been blown up a bit for popular consumption in the movie, and that both can coexist, but that's only a suspicion. Cosmological evidence for the MV is great, but still seems "indirect" in a similar sense to subatomic evidence (imho) - unless we see a "cold spot" or something in the CMBR that indicates a domain wall within observational reach (or a "dark flow" which I think might be a prediction of MV theory?) we have to deduce it from theory in the same way we do from observations of which particles exist. It's the best theory we've thought of so far, of course! - but maybe there's something better we haven't thought of yet. Of course. SUSY also sounds like a neat idea, and allegedly it's the only (?) such theory that fits in with general relativity. Not that I understand why that is, even to a first approximation. But I doubt they meant that SUSY *with the observed particle masses* is the only theory that could fit with GR, so that still (ISTM) leaves room for a MV to give a smorgasbord of different particles across the whole schmeer... -- You received this message because you are subscribed to the Google Groups "Everything List" group.
