joigus Posted January 1 Share Posted January 1 I think we're living in an age of confusion and that this confusion must have been pretty much unavoidable all along. Copenhagen's interpretation works like a dream for anything that doesn't deeply involve questions of very early cosmology, quantum gravity, or vacuum energy. Little surprise there: Where does the universe come from? Why is there something rather than nothing? What is time? You can't get more essential than that. I also think there's the social factor that not many high-profile theorists since the likes of Einstein and Schrödinger have been attracted to this problem nearly compellingly enough. That's probably because so far there hasn't been much at stake from the point of view of solving fundamental problems --or getting a university tenure. This particular factor, I feel, could be about to change in the decades to come. As to interpretations, one possibility is that, wherever the description of physical systems & processes hinges on QM, we've finally hit a fundamental logical obstacle which could have to do with the completeness vs consistency of mathematics itself, which we know by now to be an actual issue. The reason being: Why not? If that's the case, we will have to give up on matters of interpretation. My personal feeling is that we haven't taken the question seriously enough. And my battlecry --or baby cry, who knows--, is that we must change the attitude to that of the cartographer: Our quantum-state variables, and space-time and internal-gauge, spin variables, etc. would be but a parametrisation of physics that simply cannot do the job of explaining everything at every level. At some point we have to drop them, propose new variables, and explicitly build formulae connecting the different domains. This is very similar to what a cartographer who wants to faithfully describe Antarctica must do if she's been working only with the Mercator projection previously. In a way that's what we do all the time. As to my own interpretation, I think there must be some kind of a non-linear dynamics of solitons, kinks and domain walls, etc, going on in the gauge degrees of freedom, that's not completely inconsequencial, complex enough that it's gone unnoticed for all these years as a possibility, and can perhaps under suitable ancillary hypothesis be statistically related with a De Broglie-Bohm model as an approximation. So in that sense I think the De Broglie Bohm interpretation, although it cannot be the whole story, does capture something important as a crude approximation. Sorry for the split infinitive, and for so many words for what basically is my two cents. 1 Link to comment Share on other sites More sharing options...
