> "Essentially solved" is at best a euphemism for "we speculate that this will solve it". Hardly conclusive. No, it means that it's actually been solved. If you compare the theoretically predicted number of satellite galaxies to the observed number, there's no discrepancy any more. There was a discrepancy a decade ago. There isn't any more, both because of better observations (which detect more faint galaxies) and because of better understanding of the consequences of LCDM (in particular, how reionization and supernova feedback affect star formation in low-mass galaxies). > rampant disinterest in challenging orthodoxy That's just not the case. There's huge interest in challenging orthodoxy. If there were a MOND-like theory that worked, there would be tons of astrophysicists who would be very excited to work on it. The problem is simply that none of the proposed MOND theories match the wide range of observations that LCDM does. LCDM is a simple theory that works remarkably well, much to the chagrin of the astrophysics community. It would be really exciting to find a problem in LCDM, and a lot of astrophysicists spend their time searching for such problems. See, for example, the excitement generated by the possible Hubble constant tension.
