Program

In the first part of the course, we illustrate some kinematic properties of disk and dwarf galaxies, including the acceleration scale, the baryonic Tully-Fisher relation, and the galaxy disk stability, that hardly fit within the currently standard Cold Dark Matter model. Over the years, a number of ad hoc modifications to this model have been proposed to solve some of these tensions.

In the second part of the course, we show that, in epistemology, this approach is called degenerating problemshift. This condition might prelude to a substantial scientific revolution. In fact, most of these tensions are actually novel predictions in a different theory proposed in 1983, called Modified Newtonian Dynamics (MOND). The observed kinematic properties were indeed predicted by this model years in advance of their discovery, as expected in a sound progressive theory.
