### Calabi-Yau from WMAP

Some media seem to be led by wise men and women and actually report some meaningful and exciting albeit slightly speculative things about physics. For example,

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.
