"Webb22 dec. 2006 · If true, Thurston's insight would solve the Poincaré conjecture, because a sphere is the only one of the eight geometries that admits a trivial fundamental group. In 1982, Richard Hamilton (now of Columbia University) proposed a possible strategy for proving it: Start with any lumpy space, and then let it flow toward a uniform one. " - The poincaré sphere
