Fermi paradox
The Fermi paradox is the discrepancy between the lack of conclusive 
evidence of advanced extraterrestrial life and the apparently high 
likelihood of its existence. As a 2015 article put it, "If life is so 
easy, someone from somewhere must have come calling by 
now."Italian-American physicist Enrico Fermi's name is associated with 
the paradox because of a casual conversation in the summer of 1950 with 
fellow physicists Edward Teller, Herbert York, and Emil Konopinski. 
While walking to lunch, the men discussed recent UFO reports and the 
possibility of faster-than-light travel. The conversation moved on to 
other topics, until during lunch Fermi blurted out, "But where is 
everybody?" (although the exact quote is uncertain).There have been many 
attempts to resolve the Fermi paradox, such as suggesting that 
intelligent extraterrestrial beings are extremely rare, that the 
lifetime of such civilizations is short, or that they exist but (for 
various reasons) humans see no evidence.
