On July 19, 1952, a large number of people, including air traffic controllers, saw six unidentified flying objects in restricted air space over Washington, D.C. The event lasted fourteen minutes and made national news. It inspired Louis A. Gardner to write Albert Einstein. He wanted Einstein’s opinion: were UFOs the result of intelligent alien life, top secret technology created by humans or something else.
Albert Einstein wrote back. His letter is above. I’m surprised by Einstein’s response. I would have thought he’d be curious. But then again… maybe he wasn’t because he already knew the answer.
