Adam Frank (The Little Book of Aliens) is a physicist, astronomer, and writer. Adam joins the Armchair Expert to discuss how he dealt with being an outsider in school, why he was drawn to science fiction, and how he discovered a secret language in mathematics. Adam and Dax talk about what the search for intelligent life outside Earth looks like, how common it is for other planets to have water, and what the concept of a liquid brain is. Adam explains why people are so obsessed with UAPs, why looking into space is like looking back in time, and how he thinks climate change is affecting the planet.
