explain a new way to determine some information about the correct vacuum - if I use the optimistic language, to determine the shape of the Calabi-Yau - by an accurate analysis of the WMAP data. This is based on
by Gary Shiu and Bret Underwood who consider the warped deformed conifold in the context of DBI inflation and find some distinct signal of a particular geometry. See also
by Henry Tye for a recent update explaining the attempts to prove string theory and figure out some unknown data about its realization in Nature from precision astronomical observations.
