It is shown here that a model for inertial mass,
called quantised inertia, or MiHsC (Modified inertia by a
Hubble-scale Casimir effect) predicts the rotational acceler-
ation of the 153 good quality galaxies in the SPARC dataset
(2016 AJ 152 157), with a large range of scales and mass,
from just their visible baryonic matter, the speed of light and
the co-moving diameter of the observable universe. No dark
matter is needed. The performance of quantised inertia is
comparable to that of MoND, yet it needs no adjustable pa-
rameter. As a further critical test, quantised inertia uniquely
predicts a specific increase in the galaxy rotation anomaly
at higher redshifts. This test is now becoming possible and
new data shows that galaxy rotational accelerations do in-
crease with redshift in the predicted manner, at least up to
Z = 2.2.
