    The 10 Best Great Filters That Could Explain the Fermi Paradox (Narration Only)

    From abiogenesis to AI, we rank the top Great Filter candidates and test them against the data to see which best explains the Fermi Paradox. Is the universe empty, or just dangerous? We explore ten filters—cosmic, biological, and civilizational—that could silence civilizations before they spread.
