Wise Conjecture: Proof that ended an era in 3D shapes

This episode explores the thirty-year quest to create a periodic table for the shape of space.
Mathematician William Thurston revolutionized geometry by proposing that every three-dimensional manifold is composed of pieces belonging to one of eight specific geometric environments.
While most categories are rare, the vast majority of spaces are hyperbolic—bizarre "dark matter" shapes that are larger on the inside than the outside and expand exponentially.
Thurston hypothesized that these chaotic hyperbolic worlds are secretly built upon a highly structured skeleton of "surface bundles," which only become visible when the space is "unrolled" through a mathematical tool called a covering space.
This obsession to find order within intense curvature remained a dream for decades because the wild nature of hyperbolic geometry tended to rip apart any surface researchers attempted to construct.
