Excellent summary of the current state of the argument as to whether binary stars observed in Gaia favour dark matter or modified gravity. TLDW : prominent MOND supporter completely changes their mind and finds 16 sigma (!) significance evidence that MOND doesn't work. Previous test using the same data included points with much too large errors and found the opposite result. Doesn't actually validate dark matter, just disproves MOND.
