FERMI PARADOX. “A particularly trenchant formulation of this inconsistency is that of Hart (1975), who dubs the fact that there are not aliens on Earth now “Fact A.” This fact is supposedly surprising because the time for an exponentially growing population to travel to every star in the Galaxy under even rather conservative assumptions of the feasibility of interstellar travel is short compared to the age of the Galaxy. Many have used this and similar articulations of the Fermi Paradox to argue that the entire endeavor of SETI is a “waste of time”.”
