The Dark Matter Podcast - Bye Stacy Maga

Stacy McGaugh is an American astronomer and professor at Case Western Reserve University in Cleveland, Ohio. His primary focus has been in physics problems related to the distribution of matter and the dynamics of galaxies. He's a proponent of Modified Newtonian Dynamics (MOND), which tweaks our understanding of gravity to allow galaxies to form and move without the need of a traditional dark matter halo. The theory was originally published in 1983 by Israeli physicist Mordehai Milgrom. MOND has been effective at predicting the behavior of some galaxies, like the Dwarf Spheroidals attached to Andromeda, however it has yet to explain some anomalies like the collision of the Bullet Cluster. In cases with high gravitational lensing and little ordinary matter the theory has been shown to break down. Stacy discusses successes of his approach to astrophysics and what can be improved on in the future.
