MiHsC/quantised inertia does too!<br /><br />Looking at the data McGaugh presented in his Fig. 3, MiHsC differs slightly from his relation but also agrees with the data. Furthermore MiHsC/quantised inertia is a proper physical theory, unlike MoND which is just an empirical relation that needs a tuning parameter to be set (a0). MiHsC predicts it all just from c and the Hubble scale.
