What Counts as Life | Astrobiology Series Part 1
This is the first installment in the astrobiology series, adapted from the astrobiology course Dr. Dakotah Tyler taught at university. Expect to learn what astrobiology actually means, why sci-fi aliens are usually too human, why UFO claims require careful assumptions, and why defining life is harder than it sounds. We cover viruses, dormant microbes, ideas as information systems, chemical possibility, life as a physical process, habitability, synthetic life and biosignatures. As always, lead with curiosity.
