> There's nothing wrong with studying condensed matter physics, and there is a huge amount to learn. But I don't see a conceivable way in which discoveries made by studying complex behavior closer to our scale will help solve quantum gravity or dark matter. Interestingly, this does actually work out. Excitations in solids are often described by quantum field theory, and many of the exotic ideas of field theorists in fundamental physics turned out to be things you can actually find in a sufficiently exotic material.
