MOND predictions are compared with the mass discrepancy , \Gamma ( the dynamical-to-baryon mass ratio ) deduced from the recently measured rotation curve , for the gas-rich , dwarf galaxy KK246 , “ the only galaxy observed in the local void ” . KK246 is special in at least two regards : a . It is , to my knowledge , the record holder for the largest mass discrepancy deduced from a rotation curve , \Gamma \approx 15 . b . It is very isolated , residing in a large , very empty void . I also discuss another extreme case : Andromeda IV , a dwarf considered here for the first time in light of MOND , with a very large mass discrepancy , \Gamma \approx 12 , also conforming accurately to the MOND prediction . In both cases , MOND predicts \Gamma , or the total dynamical mass at the last observed radius , from only the knowledge of the small mass of baryons . If MOND is accepted as the root of the mass discrepancy , these are just two more expected , albeit reassuring , conformities . However , in the framework of the dark-matter paradigm–where the mass discrepancy is strongly dependent on the buildup history of a galaxy–every new such conformity with a tight law is another difficult-to-understand surprise , and does carry a new import : What , in the \Lambda CDM paradigm , would prevent such galactic baryons from residing in a halo of half , or twice , the observed rotational velocities , instead of selecting exactly the velocities predicted by MOND ? This conundrum is especially poignant for KK246 , whose great isolation points to a relatively unique buildup history . This note underscores the individual importance of each galaxy as a new test , as opposed to the view of them all as a statistical ensemble .
