Is Dark Matter Real? - With Sabine Hossenfelder

Explore the controversial topic of dark matter in this thought-provoking lecture by physicist Sabine Hossenfelder. Delve into the evidence supporting and challenging the existence of dark matter, and examine alternative explanations for observed astronomical phenomena. Learn about the concept of superfluid dark matter, which combines aspects of dark matter theory with modifications to general relativity. Discover how this innovative approach might resolve discrepancies in galactic rotation curves and other cosmic mysteries. Gain insights into the ongoing scientific debate surrounding dark matter and the potential implications for our understanding of the universe.
