Really Weird Stuff in the Universe - some far-out concepts and theories

Really weird stuff in the Universe takes things a step further. There are some far-out and unbelievable (and hard to understand) concepts and theories out there and this page lists them, with links to other pages that tell you more, hopefully in such a way that you'll be at least halfway to understanding them.
