OK, this has nothing to do with brewing, but I had to share this. I saw a clip of Neil DeGrasse Tyson. I love listening to him, and I feel it illustrates a point I had made on another blog, at http://joestarot.bravesites.com. I'm not sure if I got this exactly right, but it's as close as I can remember it.
"One thousand years ago, we "knew" the Earth was the center of the universe. Five hundred years ago, we "knew" the world was flat. What will we "know" tomorrow?"
My point is that we don't know what we think we do. What was once nuts is now accepted. What is nuts now may one day be true.
