Tried to prove my uncle wrong about the moon landing and lost him at the reflector argument
My uncle swears the 1969 landing was filmed in a studio, so I brought up the retroreflectors the Apollo crews left on the surface that labs in College Park still bounce lasers off today. He said the reflectors could've been dropped by a robot and now the whole dinner is stuck on robots. What's the one piece of proof that actually got through to someone you know?
