About this Episode

In this week's questions show, I talk about how we're in a new space race, and what this means for returning to the Moon. Of course, lots of follow up answers about the Fermi Paradox. Could Betelgeuse release gravitational waves if it explodes? And what is our responsibility if we are truly alone in the Universe?
