The Drake equation is a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way Galaxy. [ 1 ] [ 2 ] [ 3 ] The equation was formulated in 1961 by Frank Drake , not for purposes of quantifying the number of civilizations, but as a way to stimulate scientific dialogue at the first ...

This is an accepted version of this page This is the latest accepted revision, reviewed on 8 February 2025. Discrepancy of the lack of evidence for alien life despite its apparent likelihood This article is about the absence of clear evidence of extraterrestrial life. For a type of estimation problem, see Fermi problem. Enrico Fermi (Los Alamos 1945) The Fermi paradox is the discrepancy ...
Nucleic acids may not be the only biomolecules in the universe capable of coding for life processes. [1]Astrobiology (also xenology or exobiology) is a scientific field within the life and environmental sciences that studies the origins, early evolution, distribution, and future of life in the universe by investigating its deterministic conditions and contingent events.

Brian discusses the Wow! signal, Drake equation and explains the ingredients needed for an intelligent civilization to evolve in the universe – the need for a benign star, for a habitable planet, for life to spontaneously arise on such a planet and the time required for intelligent life to evolve and build a civilization. Brian weighs the ...
Ward and Brownlee argue that the universe is fundamentally hostile to complex life and that while microbial life may be common in the universe, complex intelligent life (like the evolution of biological complexity from simple life on Earth) requires an exceptionally unlikely set of circumstances, and therefore complex life is likely to be extremely rare.
