This video explores the “missing mass” problem in modern cosmology: the discovery that galaxies and galaxy clusters move as if they contain far more matter than we can see. Tracing the story from early 20th‑century astronomy to the work of Fritz Zwicky and Vera Rubin, it follows how careful measurements of galaxy rotation curves, galaxy clusters, and gravitational lensing led scientists to propose dark matter as a hidden, dominant component of the universe.

Through the history of these observations, we look at why normal stars, gas, and dust cannot explain the measured gravity, and how this mystery reshaped physics and cosmology. The episode sets out the main ideas behind dark matter, the evidence that supports it, and the ongoing search for what this unseen mass is made of, placing today’s research in the wider story of how we came to understand the structure and evolution of the universe.
