Black Holes. Explained. For 1.5 Hours.
Black holes are not just the strangest objects in the universe, they're the sharpest test we have of how reality actually works. This episode explores how these extreme cosmic laboratories force general relativity and quantum physics into direct confrontation. We look back through a decade of content to understand their formation and the theoretical diagrams that describe them.
