This is a long article I wrote based on a paper I wrote in college. I’ve thought about trying to sell it, but thought maybe I’d rather give it away here on my website to anyone interested.
The article is a non-technical examination of the possibility that extraterrestrial life is out there, and how likely intelligent life might be. No science background required, it’s written for an audience with no experience in the areas of science discussed. As of now it’s a living document, subject to change and editing, so let me know what you think!
