It goes glub, glub, glub to the bottom of the sea. <BR/><BR/>I will think about it when string theorists are able to explain something. And, btw, AdS/CFT is not equal string theory and QCD does not have N = infinity, and heavy ion collisons don't take place in thermal equilibrium.<BR/><BR/>Sabine Hossenfelderhttps://www.blogger.com/profile/06151209308084588985noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-1154503355549966732006-08-02T03:22:00.000-04:002006-08-02T03:22:00.000-04:00Hi Bee, thanks for that link to the higher dimensi...Hi Bee, thanks for that link to the higher dimensional artwork, it certainly brings a further perspective on xtra dimensions on different scales. love it. <BR/>Here's hoping you are having a good week.
