The Fermi Paradox Why Enrico Fermi Asked Where Is Everybody

The Fermi Paradox questions why, given the vast age and size of the Milky Way galaxy (100,000 light-years wide), we have not detected any evidence of extraterrestrial civilizations despite billions of years for intelligent life to potentially develop. Three main explanations exist: intelligent life may be extremely rare, civilizations may not survive long enough to spread, or we may be listening for the wrong signals for too short a time. Notably, human radio signals have only reached about 100 light-years, which is negligible on galactic scales, suggesting our silence may simply mean we've barely started listening rather than that we are alone.
