Is There A Basic Answer To The Fermi Paradox?
Summary
This episode explores the Fermi Paradox, proposing that the formation of the first eukaryotic cell was a rare "Great Filter" that explains the absence of aliens. The hosts discuss a new study suggesting that prokaryotic life hit energetic and computational limits, making the endosymbiotic event that created eukaryotes a critical, potentially unique survival mechanism. By examining how this biological "big bang" allowed for complex life to emerge from a near-extinction event, the show argues that if this transition was a fluke, most civilizations in the universe may have stalled at the micro…
