The galaxy is old enough for a spacefaring civilization to have spread across it many times. Proposed answers range from life being rare, to civilizations being short-lived, to our searches being too narrow. Biosignature searches in exoplanet atmospheres are the first measurements that could constrain the answer.
Posed 1950, Enrico Fermi: "Where is everybody?".
