Is Dark Matter Real? - With Sabine Hossenfelder

This talk examines observational evidence for dark matter, including galaxy clusters, galactic rotation curves, gravitational lensing, the cosmic microwave background, and structure formation. It also considers modified gravity and superfluid dark matter as alternative explanations and discusses possible tests.
