In this episode, Samuel Arbesman has the pleasure of speaking with Stephen Webb. Stephen is a physicist and the author of numerous books, including one entitled "If the Universe is Teeming with Aliens… Where is Everybody?", the second edition of which includes 75 solutions to the Fermi Paradox. Samuel wanted to talk to Stephen to explore the nature of the Fermi paradox — essentially, if the universe should have extraterrestrial intelligences, why don't we see them? — and how it forces us to think about our place in the universe.

Samuel and Stephen have a chance to examine what the Fermi paradox is, the interdisciplinary nature of the approaches to this puzzle, science fiction as a "playground for thought experiments," and the three main categories for how people approach the Fermi paradox. They discuss some of the fun answers to the paradox, Stephen's personal take on it, how scientific and technological advances have affected how we think about the paradox, and even how AI has changed how we might think about intelligence in the universe.
