Beyond “Fermi’s Paradox” IV: What is the Rare Earth Hypothesis?
Looking to answer the question of “where are all the aliens,” some scientists have suggested that planets like Earth might actually be very rare.
Beyond “Fermi’s Paradox” III: What is the Great Filter?
In 1996, economist/futurist Robin Hanson proposed a possible resolution to the Fermi Paradox: there’s a “Great Filter” that prevents intelligent life from becoming advanced.
Beyond “Fermi’s Paradox” II: Questioning the Hart-Tipler Conjecture
Welcome back to our Fermi Paradox series, where we take a look at possible resolutions to Enrico Fermi’s famous question, “Where Is Everybody?” Today, we examine the possibility that the reason we’ve found no evidence of alien civilizations is because there are none out there. It’s become a legend of the space age. The brilliant …

Beyond “Fermi’s Paradox” I: A Lunchtime Conversation- Enrico Fermi and Extraterrestrial Intelligence
Welcome back to our Fermi Paradox series, where we take a look at possible resolutions to Enrico Fermi’s famous question, “Where Is Everybody?” Today, we examine the lunchtime conversation that started it all! It’s become a kind of legend, like Newton and the apple or George Washington and the cherry tree. One day in 1950, …
Beyond “Fermi’s Paradox” XII: What is the Waterworlds Hypothesis?
Is it possible that the reason we haven’t heard from any aliens is because there’s too much water out there?
Beyond “Fermi’s Paradox” IX: What is the Brief Window Hypothesis?
In this latest installment in our Fermi series, we take a look at the possibility that advanced civilizations only have a brief window within which to communicate.
After all of This Time Searching for Aliens, is it The Zoo Hypothesis or Nothing?
In 1950, during a lunchtime conversation with colleagues at the Los Alamos National Laboratory, famed physicist Enrico Fermi asked the question that launched a hundred (or more) proposed resolutions. “Where is Everybody?” In short, given the age of the Universe (13.8 billion years), the fact that the Solar System has only existed for the past …

Why Don't We See Robotic Civilizations Rapidly Expanding Across the Universe?
In 1950, while sitting down to lunch with colleagues at the Los Alamos Laboratory, famed physicist and nuclear scientist Enrico Fermi asked his famous question: “Where is Everybody?” In short, Fermi was addressing the all-important question that has plagued human minds since they first realized planet Earth was merely a speck in an infinite Universe. …

Civilizations are Probably Spreading Quickly Through the Universe
New research shows how intelligent life might expand in an ever-expanding Universe, which has serious implications for SETI and the fate of our civilization.
Do Advanced Civilizations use Black Holes as Giant Quantum Computers?
A new study suggests that advanced civilizations could used black holes as massive quantum computers, a theory that has implications for SETI.
