Watch Universe Today’s Fraser Cain School the Cast of ‘Interstellar’ on Black Holes

Space fans have been waiting for the movie “Interstellar” which opens in theaters this Friday, November 7. Today, the cast and crew of Interstellar did a special Google+ Hangout on Air at the Smithsonian’s National Air and Space Museum. Host Kevin Frazier and the cast had their chance to throw a few space-related questions to the astronauts and scientists assembled for the Hangout. Our own publisher, Fraser Cain, was the unfortunate target for the question, “can you explain what a black hole is?” You can watch the entire Hangout above; Fraser schools them at about 35:33.
