John Mather '68 on the History of the Universe

Nobel Laureate John Mather '68 tells the story of how the universe began with a Big Bang, how it could have produced an earth where sentient beings can live, and how those beings are discovering their history. Mather, co-recipient of the 2006 Nobel Prize in Physics for providing increased support for the Big Bang theory of the universe, is a senior astrophysicist at NASA's Goddard Space Flight Center. He includes in his talk, the 2007 McCabe Lecture, Einstein's biggest mistake, how Edwin Hubble discovered the expansion of the universe, and NASA's plans for the next great telescope in space, the James Webb Space Telescope.
