Has anyone heard of this proposed test of string theory's extra dimensions? What do you think? Within the realm of reason? Doable within the next decade? Robert === http://www.news.wisc.edu/13422.html ...physicists at the University of Wisconsin-Madison have devised an approach...

What exactly is this and where did it come from? In detail if possible please

As a fan of easy reading material on thorny topics, I thought some might find this interesting: http://www.arxiv.org/abs/astro-ph/0601307 Cosmic Microwave Background Mini-Review

i read a article and i can't really understand all of it. I get some but then its beyond me. If someone could briefly summarise it so i can understand. Here is the link. http://www.aip.org/enews/physnews/2003/split/624-1.html
