Black holes: to the event horizon and beyond NOVA Now

Black holes: they’re dense, elusive, light-absorbing pockets of spacetime that are critical to our understanding of the universe. But black holes are difficult to peer into, so there’s a lot scientists still don’t know. This leaves some room for science fiction to take over. Tall tales of galactic adventure may pair well with popcorn, but they also blur the lines between fact and fiction. To explore what humanity knows—and what we think we know—about black holes, Dr. Alok Patel and a theoretical cosmologist journey to Earth’s closest black hole: the Milky Way’s own Sagittarius A*, approximately 26,000 light-years away. (Don’t worry; no scientists or science nerds were harmed in the making of this podcast.)
