> that our observations are incomplete and our models are wrong. I'd say that's a given regardless of the DM mystery. It's consensus that QM and GR are incompatible and that we need a new theory out of which both of these come out as a special case. String theory was considered a hopeful contender for that for a while. And that we haven't observed everything to a satisfying degree yet should be obvious. > Isn't this essentially the same problem with Dark Matter though? They keep looking for it, not finding it and proclaiming "well, it must be somewhere else!". No (unless you mean "where" in parameter space), we have a pretty good idea where it is thanks to gravitational lensing surveys. We don't what it is.
