Numerical Testing of The Rare Earth Hypothesis using Monte Carlo Realisation Techniques

, 2010
The Search for Extraterrestrial Intelligence (SETI) has thus far failed to provide a convincing detection of intelligent life. In the wake of this null signal, many "contact pessimistic" hypotheses have been formulated, the most famous of which is the ...
