Astrophysics for People in a Hurry (Astrophysics for People in a Hurry Series)

by Neil deGrasse Tyson

People who believe they are ignorant of nothing have neither looked for, nor stumbled upon, the boundary between what is known and unknown in the universe.

My favorite parody of this gesture was a skit on NBC’s Saturday Night Live, shortly after the Voyager launch, in which they showed a written reply from the aliens who recovered the spacecraft. The note simply requested, “Send more Chuck Berry.”
