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.

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.
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 …

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, …
Is it possible that the reason we haven’t heard from any aliens is because there’s too much water out there?
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 …

A new study suggests that advanced civilizations could used black holes as massive quantum computers, a theory that has implications for SETI.
A new study takes a look at Von Neumann probes and asks the really important questions: “why would aliens send them?” and, “where might we find them?”
SpaceX CEO Elon Musk has laid out a scenario for space travel that calls for his company’s Starship launch system to take on its first orbital test flight as soon as January. Starship could go through “a dozen launches next year, maybe more,” and be ready to send valuable payloads to the moon, Mars and …

According to a new study, humanity could become an interplanetary species in this century, interstellar by the 23rd, and intragalactic by the 24th.
