Tyson doesn't have any initials after his name, nor should anyone believe anything he writes as fact. Given that the half life of knowledge for most areas of expertise is 5-10 years, anything unique I learned in school 20 years ago is probably useless. I do, however, have a few good looking kids a nice house and car, so based on that image, I'm at least as qualified as your typical general authority. Lastly, and certainly most importantly, I am an ordained minister in the Church of the Flying Spaghetti Monster, may we all be touched by his noodly appendages. All other gods probably don't exist.
