Ever wanted to know how music affects your brain, what quantum mechanics really is, or how black holes work? Do you wonder why you get emotional each time you see a certain movie, or how on earth video games are designed? Then you’ve come to the right place. Each week, Sean Carroll will host conversations with some of the most interesting thinkers in the world. From neuroscientists and engineers to authors and television producers, Sean and his guests talk about the biggest ideas in science, philosophy, culture and much more.
Recent years have seen a revolution in the study of exoplanets, planets that orbit stars other than the Sun (or don’t orbit stars at all). After a few tentative detections in the 1990s, dedicated instruments in the 2000s have now pushed the number of known exoplanets into the thousands, enough to begin to categorize their distribution and properties. Today’s guest is John Asher Johnson, one of the leaders in this field. We talk about the various different ways that exoplanets can be detected, what we know about them know, and what might happen in the future.
