Pablo Sobron

Pablo Sobron of the SETI Institute discusses how studying the deep ocean floor informs the search for extraterrestrial intelligence. Jeffrey Hangst talks about the observation of freefalling antimatter, and the possibility of identifying differences in how matter and antimatter respond to gravity. The episode explores underwater chimney systems, analyzing sample composition using spectroscopy, and scanning the seabed with lasers to identify rare elements and minerals for undersea mining and potential exploration of other moons.
