Dr. Chiara Mingarelli (@gravitate_to_me), a Marie Curie Fellow in gravitational wave astrophysics at Caltech, joins the proceedings to talk about low-frequency gravitational waves, pulsar timings arrays and black hole binary systems with masses that are billions of times that of the Sun. This episode was recorded before LIGO's recent announcements confirming the detection of gravitational waves.

One of the biggest scientific breakthroughs of our time calls for an emergency special episode featuring returning guests Dr. Jamie Rollins and Dr. Larry Price, both of whom worked on LIGO, the device that for the first time in history confirmed the existence of gravitational waves, along with theoretical astrophysicist and black hole expert Dr. Janna Levin. Topics discussed include Matt's surprising illness, science fluff, Marco Drago's discovery?, How LIGO works, 30 solar mass black holes, test signals, the actual paper explaining the recent gravitational wave findings, Janna's new book, Relativity 101, BICEP's failure, new black holes, Scorpion!, our T-shirts, Apple vs. the FBI and what the point of all this is.
