#56 - Leslie Looney – Why a Truly Advanced Civilization Is Defined by Curiosity, Aliens, and Astronomy
Fri Feb 06 2026
Leslie Looney is a professor of Astronomy at the University of Illinois Urbana-Champaign. His research focuses on star formation, the early evolution of planets, and building the powerful telescopes and observational tools needed to explore our universe.
In this episode, we explore how stars and planets come to life, why building a giant telescope on the Moon could lead to revolutionary discoveries, and the idea that the universe itself is fundamentally unimaginable.
At the core of our conversation is one powerful idea: whether we're human, alien, or artificial, the mark of a truly advanced civilization is curiosity. The unstoppable desire to explore, discover, and understand our place in this vast, unimaginable universe.
