Extraterrestrial Life & the Fermi Paradox
The Fermi Paradox
The framing problem for this whole domain: the apparent contradiction between plausible estimates that the galaxy should host many communicating civilizations, and the total absence of confirmed contact or evidence for any of them.
Proponents
Enrico Fermi, Michael H. Hart
Evidence For
Grounded in a real and startling numerical tension between plausible galactic civilization counts and zero confirmed observations to date.
Evidence Against
Critics note "absence of evidence" arguments are inherently weak given how limited, brief, and narrow our searching has been on a cosmic timescale.
