The Fermi Paradox

The Fermi Paradox is an argument originally made by physicists Enrico Fermi and Michael H. Hart, who presented an apparent contradiction between how many alien civilizations are thought to be out there and our lack of evidence for their existence.

If the Drake Equation is right and there are literally millions of intelligent species in our galaxy alone, it is puzzling that we have received no signals or messages from any of them. This is known as the Great Silence. 

There have been some incredibly interesting solutions proposed over the years, one of which includes the Simulation Theory. (Source | Photo)
