What We Know, What We Don't

Tyson, director of the Hayden Planetarium in New York City, will reflect on highlights from his scientific career — including being blamed by adults and school children alike for demoting Pluto. Tyson will also share anecdotes from his time as space policy advisor to NASA, to the Bush White House, and to school systems. Tyson will further reflect on the Obama space plan, Mars Rovers, the search for life, Dark Matter, Dark Energy, the Large Hadron Collider and progress on a theory of everything.
