WebFor instance, in the Rare Earth Hypothesis, there is a discussion about something called the Galactic Habitable Zone. This is a region within a spiral galaxy, like the Milky Way, in which the cosmic conditions are favorable for life to develop on a planet within that region. The Rare Earth Hypothesis contends that this region is fairly small. The Drake equation is a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way Galaxy. 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 … See more The Drake equation is: $${\displaystyle N=R_{*}\cdot f_{\mathrm {p} }\cdot n_{\mathrm {e} }\cdot f_{\mathrm {l} }\cdot f_{\mathrm {i} }\cdot f_{\mathrm {c} }\cdot L}$$ where See more In September 1959, physicists Giuseppe Cocconi and Philip Morrison published an article in the journal Nature with the provocative title … See more Original estimates There is considerable disagreement on the values of these parameters, but the 'educated guesses' used by Drake and his colleagues in 1961 were: • R∗ = 1 yr (1 star formed per year, on the average over the … See more Criticism of the Drake equation follows mostly from the observation that several terms in the equation are largely or entirely based on conjecture.
