Episode 182: Planet Nine or Black Hole One, with Jakub Scholtz

Feature Guest: Jakub Scholtz

We've long believed that membership in the solar system's planetary family was limited to those eight planets we learned about in grade school. But then astronomers began to raise the possibility of a new super-Earth-sized planet, five to ten times the mass of Earth, orbiting far off in the outer solar system. Now if you thought the concept of Planet Nine was astonishing, consider if the mysterious body wasn't a planet at all - but a black hole. That's right, Planet Nine might be Black Hole One, our own solar system's very first singularity. Today we're joined here at The Star Spot by astrophysicist Jakub Scholtz, co-author of a new study making the case for this fascinating proposal.
