We live in an astronomically large universe (no pun intended). A man named Frank Drake
recognized this. How can we estimate the number of technological civilizations that might exist
among the stars? Although incredibly inaccurate for any scientist's taste, Drake developed
something very useful. Drake evaluated the incredible probability and inevitability of life
compared to the odds of our vast universe. To assess the probability of extraterrestrials in our
universe, astrobiologists use a method called the Drake Equation (SETI). Formulated by Frank
Drake of SETI (Search for Extraterrestrial Technology Institute), the mathematical equation
outlines the variables to yield the possibility of picking up communicable technology by other
intelligent life beings (represented by the variable N). A unique aspect of the equation is that N
does not produce a concrete answer. So while we can outline the variables it takes to yield life,
we cannot assign a number on it.
Many scientists, for that reason, completely throw out The Drake Equation. However, while
Drake failed to tangibly assess a numerical value, he did satisfy one providential aspect in this
question. Drake, by assigning variables that must satisfy to yield life, examines two natural
phenomenons that govern life: the process of natural selection and the development of from
simplicity to complexity. These profound aspects of biology leave us believing that life is, if you
will, 'easy' and perhaps even inevitable. It may arise through a blanket of long evolution that
begins (as the Drake Equation does) with the formation of stars. Those stars tend to have planets,
which host life, which engenders intelligence and consciousness. The Drake Equation replicates
the theory that life on earth is merely the latter portion of evolutionary processes amongst others
that are on their way to be the same thing.
Conclusively, I hope there is life beyond earth, and I hope we find it. The reason lies in the child
that sat agaze at the sky —the same child I spoke of earlier—the child that was me, and perhaps
you. I hope there is life because I would like to believe that there is something more to this grand
universe than what I see when I wake up and walk through our monotonous days on earth. For
years people have tried to escape from this monotony and have failed in doing so. I would like to
think they were looking in the wrong places. If you really want a show, a spell-binding
experience, transcendence, wonder, and passion, the answer is vulnerable. All you have to do is
look up.
