PBS Space Time
Space Time explores the outer reaches of space, the craziness of astrophysics, the possibilities of sci-fi, and anything else you can think of beyond Planet Earth with our astrophysicist host: Matthew O’Dowd.
Matt O’Dowd spends his time studying the universe, especially really far-away things like quasars, super-massive black holes, and evolving galaxies. He uses telescopes in space to do it. Matt completed his Ph.D. at NASA’s Space Telescope Science Institute, followed by work at the University of Melbourne and Columbia University. He’s now a professor at the City University of New York’s Lehman College and an Associate at the American Museum of Natural History’s Hayden Planetarium.
Previous host Gabe Perez-Giz is an astrophysicist who studies black hole physics. He received his Ph.D. from Columbia University and also hosted PBS Infinite Series.
PBS Space Time is rare in that it treats its audience as intelligent adults – diving into genuinely advanced physics and cosmology without dumbing it down. It’s the best place on YouTube to actually understand topics like quantum mechanics, general relativity, and the nature of the universe.
