Neil deGrasse Tyson sets off on the Ship of the Imagination to chase a single comet through its million-year plunge toward the sun.
Later, Tyson visits the birthplace of Sir Isaac Newton and retraces the unlikely friendship between Newton and brilliant polymath Edmond Halley (guest voice Cary Elwes). It was Halley's patience and generosity which allowed Newton to conquer his fear of isolation and find the courage to publish his masterwork, “Principia Mathematica,” which launched a science revolution in the all-new "When Knowledge Conquered Fear" episode of COSMOS: A SPACETIME ODYSSEY airing Sunday, March 23 (9:00-10:00 PM) on FOX 50.
