What if everything you knew was a lie? Discover the Zoo Hypothesis, a startling theory that suggests we're not alone in the ...

If the universe is so vast and old, why haven’t we found any signs of extraterrestrial civilizations? Among the many possible ...

It became known as Fermi's Paradox: if the Earth isn't special, and the Universe is so very big with so many stars, where is everybody? Los Alamos in 1944, during the Manhattan Project.

Plenty of theories exist — which is how we know there's no actual answer. At least, not yet. In 1950, when Italian physicist Enrico Fermi posed that question, it became known as the Fermi paradox.

The Fermi Paradox brings out a sharper, more personal humbling, one that can only happen after spending hours of research hearing your species’ most renowned scientists present insane theories ...

Let’s shift gears to understand further why the Fermi Paradox gives astrophysicists fits. The Drake Equation is a simple mathematical formula first proposed by astronomer Frank Drake in 1961.

Given the Fermi Paradox, this may be as far as any civilization gets. Follow George on Twitter and friend him on Facebook.

If there are other civilizations in the Universe, then why, after 60 years of looking, haven't we found any evidence of their existence? Statistical analysis suggests that if Earth is typical ...

The paradox is attributed to Enrico Fermi, the man behind the first nuclear reactor, who once asked, "Where is everybody" after reading and discussing a New Yorker cartoon featuring aliens hopping ...

A good model helps frame the debate, but many unknowns remain. Which is, of course, why the Fermi paradox is fun. Absent hard evidence, it's fertile ground for speculation. Our knowledge of the galaxy ...
