Episode: Gravitational Redshift and Sci-Fi Body and Time Shifts
Description: Light gets redder as it climbs out of gravitational holes, and a star near the black hole at the center of the Milky Way conveniently demonstrates this beautifully. Join us for a discussion of gravitational redshift, a sci-fi discussion of time travel and body shifting, and a bit of Messier trivia.
