I have been a bit busy these days, and the free time I had for physics was expended studying.<BR/><BR/> I am not quite sure how to answer your questiones, but I´ll try anyway. The question of singularities, as the oen of the big bang, were an anmanageable the problem for string theory beore teh D-brane revolution, basically because a Javierhttps://www.blogger.com/profile/17845977289427117418noreply@blogger.comtag:blogger.com,1999:blog-34983191.post-68216577209708441782007-12-22T22:26:00.000+01:002007-12-22T22:26:00.000+01:00Right now I only see a very sparse relation betwee...Right now I only see a very sparse relation between string theory and cosmological observations. The quantum gravity effects on cosmology are bound to models that are too far from being unique. There is a wild variety of models like the R-S models, the pre big bang scenarios, etc. Some of them like the pre big bang predict observable signatures on the cosmic microwave background, but the link to Anonymousnoreply@blogger.com
