neocatastrophism means the hypothesis that life-exterminating events such as gamma-ray bursts have acted as a galactic regulation mechanism in the Milky Way upon the emergence of complex life in its habitable zone. Lexicurio rates it Sui generis — a strength score of 91 out of 100.
Why “neocatastrophism” is a great word
NEOCATASTROPHISM — [Noun] The astrobiological hypothesis that periodic, galaxy-wide cataclysms have repeatedly sterilized the Milky Way's habitable zones, thereby resetting the emergence of complex life. From the combining form neo- ("new") + catastrophism (the geological doctrine that Earth's features were formed by sudden, short-lived, violent events). Unlike uniformitarianism, which trusts in the slow, patient work of eons, or gradualism, which imagines change as a steady, cumulative climb, neocatastrophism proposes that life's story is written in fire and erasure. It is the gamma-ray burst scouring a spiral arm clean, the supernova shockwave sterilizing a billion worlds, and the cosmic clock resetting to zero by celestial accident—a reminder that our existence is less a birthright than a temporary stay of execution.
noun
- The hypothesis that life-exterminating events such as gamma-ray bursts have acted as a galactic regulation mechanism in the Milky Way upon the emergence of complex life in its habitable zone.
