Key word being observed, isn't it possible... actually, more appropriate would be likely, that there are unobserved parts of the Universe?

But space is not made of "normal matter," so if merely space separated matter and anti-matter, couldn't there be a "patch" or area of space composed of primarily anti-matter?

Hey everyone, I'm new to this forum, but that's not the purpose of this post! I was reading the article "The Universe" (by Michael S. Turner; Scientific American, Sept. 2009), and it says "at some point it [the universe] developed a slight excess of matter--about one extra quark for every billion anti-quarks." Is there proof that there is more matter than anti-matter in the universe?
