“Where are They Hiding?” –NASA’s Former Chief Scientist Says Alien Life Could Be ‘Nowhere and No-When & Two Other Theories’

In the seventh episode of Crazy/Genius, the new podcast from The Atlantic on tech, science, and culture, puts the question to several experts, including Ellen Stofan, the former chief scientist of NASA and current director of the Smithsonian National Air and Space Museum; Adam Frank, a writer and astrophysicist at the University of Rochester; Anders Sandberg, a scientist and futurist at the University of Oxford; and Tim Urban, the science essayist at Wait But Why.
