Are we alone in the universe? If not, where is everybody? An
engaging exploration of one of the most important unsolved problems
in science. Everything we know about how planets form and how life
arises suggests that human civilization on Earth should not be
unique. We ought to see abundant evidence of extraterrestrial
activity-but we don't. Where is everybody? In this volume in the
MIT Press Essential Knowledge series, science and technology writer
Wade Roush examines one of the great unsolved problems in science:
is there life, intelligent or otherwise, on other planets? This
paradox (they're bound to be out there; but where are they?), first
formulated by the famed physicist Enrico Fermi, has fueled decades
of debate, speculation, and, lately, some actual science. Roush
lays out the problem in its historical and modern-day context and
summarizes the latest thinking among astronomers and
astrobiologists. He describes the long history of speculation about
aliens (we've been debating the idea for thousands of years); the
emergence of SETI (the Search for Extraterrestrial Intelligence) as
a scientific discipline in the 1960s, and scientists' use of radio
and optical techniques to scan for signals; and developments in
astrobiology (the study of how life might arise in non-Earth like
environments) and exoplanet research (the discovery of planets
outside our solar system). Finally, he discusses possible solutions
to the Fermi Paradox and suggests way to refocus SETI work that
might increase the chances of resolving the paradox-and finding
extraterrestrials.
