But you did just disprove your own point. Scientists knew it was cold in space before anything had been sent up there, and I can know why space is cold without being a scientist (I sat through high school physics).

Our entire understanding of the universe and our society is based on listening to what other people say about something and taking their word for it. So without having fired a gun, driven a car, eaten from a restaurant or seen a film, I can get a pretty good understanding of it's flaws based on what others have reported.
