Winter 2018, GEOL 197-01: Special Topic: Are We Alone? (3). Despite estimates that there are billions of stars in the Universe (likely trillions of billions), Earth remains the only planetary body that we know has life (so far). This apparent paradox led the physicist Enrico Fermi to wonder: "where is everybody?" In this course, we explore modern thinking about the potential for extraterrestrial life, with particular focus on the concept of planetary habitability. What are the essential ingredients for the evolution of life like we know it? Our investigation focuses on relevant aspects of the planet we know best, Earth, including its formation, composition, climate, and tectonics. We also discuss the origin, history, and potential future of life on our planet. (SC) Rahl.
