What Is Hiding in 95% of the Universe?

Everything we can see — every star, every galaxy, every glowing nebula — is less than 5% of the universe. The rest is dark, invisible, and after 90 years of searching, we still don't know what it is. This is the story of dark matter: the invisible scaffolding holding the cosmos together. From Fritz Zwicky's 1933 discovery and Vera Rubin's spinning galaxies, to the LUX-ZEPLIN detector buried deep in a gold mine, and the radical theories that question whether dark matter even exists — tonight, we go into the dark. ⏱️ Chapters 0:00 The Invisible Universe 0:55 The Discovery — Zwicky & Vera Rubin 2:10 What Is Dark Matter Made Of? 4:00 What If It Doesn't Exist?
