Good thing he didn't tell them about the Earth around the Sun thing.
I wasn't aware of this. Bill Nye "The Science Guy" was booed in Waco, Texas in 2006 for suggesting the Moon did not generate its own light, but reflected light from the sun. (Update: You can find more here. Interview with the reporter here.)
Trouble started when the children's entertainer brought up Genesis 1:16, which reads: "God made two great lights -- the greater light to govern the day and the lesser light to govern the night. He also made the stars," and pointed out that the lesser light was actually a reflector.
At this point, several people in the audience stormed out, including woman with three small children who muttered, "We believe in God!" and left.
Nye was taking part in McLennan Community College's Distinguished Lecture Series, giving talks on global warming, Mars exploration, and energy consumption, but it was the moon thing that got them.
According to Morgan Matthew, "This story originally appeared in the Waco Tribune, but the newspaper has mysteriously pulled its story from the online version, presumably to avoid further embarrassment."
