A joint analysis of the Drake equation and the Fermi paradox

Por • 3 feb, 2013 • Category: Crítica

I propose a unified framework for a joint analysis of the Drake equation and the Fermi paradox, which enables a simultaneous, quantitative study of both of them. The analysis is based on a simplified form of the Drake equation and on a fairly simple scheme for the colonization of the Milky Way. It appears that for sufficiently long-lived civilizations, colonization of the Galaxy is the only reasonable option to gain knowledge about other life forms. This argument allows one to define a region in the parameter space of the Drake equation where the Fermi paradox definitely holds (Strong Fermi paradox).



Interstellar Predation Could Explain Fermi Paradox

In a casual chat over lunch back in 1950, the Italian-American physicist Enrico Fermi posed a now famous question. If intelligent life has evolved many times in our galaxy and beyond, why do we see no sign of it?. Today, Adrian Kent at the Perimeter Institute in Waterloo, Canada, puts forward another possibility. His idea is that civilisations are common, that they have interacted many times in the past but end up competing for scarce resources. When that happens, the process of evolution, operating over vast time scales, ensures that the survivors learn to keep quiet.
