In the hunt for alien life, is man truly 'the measure of all things?'
Enrico Fermi's lunchtime question at wartime Los Alamos, "Where is everybody?" has been both a gift and a problem to scientists ever since. Known as "Fermi's Paradox," it simply asks, why, since life on Earth is ubiquitous ...
Professor proposes how a black hole in orbit around a planet could be a sign of an advanced civilization
In 1971, English mathematical physicist and Nobel-prize winner Roger Penrose proposed how energy could be extracted from a rotating black hole. He argued that this could be done by building a harness around the black hole's ...

Study reports dim odds for finding alien civilizations
Are there any advanced alien civilizations elsewhere in our galaxy? We don't know. All we do know is that there is at least one. Should we be optimistic or pessimistic about finding others?
New study suggests that our galaxy is crowded or empty—both are equally terrifying
Is there intelligent life in the universe? And if so, just how common is it? Or perhaps the question should be, what are the odds that those engaged in the Search for Extraterrestrial Intelligence (SETI) will encounter it ...
