Fermi Paradox – what is it?

Here's what you need to know...

The Fermi Paradox isn't strict evidence for alien life – but more of a thought experiment
It's a famous contradiction posed by physicist Enrico Fermi
Fermi suggested that the enormous size of the universe – and the billions of Sun-like stars in the galaxy, and their planets – makes it highly likely that there is intelligent life out there
Some of these civilizations may have developed interstellar travel
But Fermi also noted that there's a significant lack of evidence for life on other planets
The chances of aliens being able to reach us are high, but there's no evidence that aliens ever have
This paradox has baffled scientists for decades
