Predictions and Outcomes for the Dynamics of Rotating Galaxies

Abstract

A review is given of a priori predictions made for the dynamics of rotating galaxies. One theory - MOND - has had many predictions corroborated by subsequent observations. While it is sometimes possible to offer post hoc explanations for these observations in terms of dark matter, it is seldom possible to use dark matter to predict the same phenomena.

36 pages (10 are references), 9 figures. Invited review for the Galaxies special Issue "Debate on the Physics of Galactic Rotation and the Existence of Dark Matter." Provides test cases for the importance of prior predictions in the application of the scientific method
