Neocatastrophism

For the idea that Earth has been affected in the past by short-lived, violent worldwide events, see Catastrophism.
Gamma-ray bursts might have regulated the advent of intelligent life

Neocatastrophism is 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.[1][2][3] It is one of several proposed solutions to the Fermi paradox since it provides a mechanism which would have delayed the advent of intelligent beings in local galaxies near Earth.
