Gravity Breaks Here, and Nobody Knows Why - Dr. Stacy McGaugh (DemystifySci +453)

Today's episode features Professor Stacy McGaugh, Director of Astronomy at Case Western Reserve University. We discuss his journey to Modified Newtonian Dynamics [MOND] via a slow growing dissatisfaction with dark matter as the sole hypothesis to explain anomolous galaxy rotation curves, touching on the missing mass, dark matter halos, and empty WIMP detectors along the way. McGaugh champions Milgrom's acceleration scale boundary, describing unique predictions that landed, including downstream JWST discoveries. The question for future scientists is why gravity changes in low density regions of the galaxy in the first place.PATREON https://www.patreon.com/c/demystifysciOUR BOOK, PARADOX LOST: https://demystifysci.com/paradoxlostHOMEBREW MUSIC :Vinyl: https://demystifysci-shop.fourthwall.com/products/vinyl-lp-secretary-of-nature-everything-is-so-good-hereStreaming: https://secretaryofnature.bandcamp.com/album/everything-is-so-good-herePARADIGM DRIFThttps://demystifysci.com/paradigm-drift-show00:00 Go!
