When Light Climbs Out of a Hole

We never get tired of Einstein being right, and once again his general theory of relativity is up to the challenge. The astroquarks take you on a tour to the black hole at the center of the Milky Way for another test of Einstein's theory of gravity, while closer to home the Japanese Hayabusa-2 mission has successfully grabbed some more asteroid rubble. Dr. Zoe Landsman, aka Beauty Astroquark, joins Josh and Jim on this walkabout with spaceships being propelled by sunlight, nerd news, and Apollo trivia.
