**The Fermi Paradox:** the discrepancy between the lack of conclusive evidence of advanced extraterrestrial life and the apparently high likelihood of its existence ([wikipedia](https://en.wikipedia.org/wiki/Fermi_paradox)).

Of the back of the [recent post of Brian Cox](https://www.reddit.com/r/alifeuntangled/comments/1s9i32w/brian_cox_on_the_danger_of_knowledge_without/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button) talking about this I thought it would be worth giving further context.

It occurred in 1950 during a casual lunchtime conversation that physicist Enrico Fermi was having with colleagues, posing the simple question:

**“But where is everybody?”**

Given the vastness of the universe—billions of galaxies, each with billions of stars—there should be countless civilizations.

And yet… we see nothing.

No signals. No evidence. No visitors.

This tension became known as the Fermi Paradox, first appearing in print in a 1963 paper by Carl Sagan. 

It forces an uncomfortable possibility:

Either intelligent life is incredibly rare… or something prevents it from lasting very long.
