SUMMARY: String theorists have a problem. They have a set of theories which could explain how all the forces in the Universe are connected. Unfortunately, it depends on the existence of tiny vibrating strings which are so small they could never be seen directly. One strategy, proposed by physicists from Yale, would be to look at the afterglow from the Big Bang, which covers the entire sky. The small strings could project much larger shadows onto this radiation which would be light-years across, and detectable from Earth.

I don't like string theory, and I predict that those changes in the spots of the CMB won't be found. But is great to be able to test the theory someway, anyway Planck (the satellite) will possibly decide over this issue

It's difficult to imagine the casting of shadows within the level of homogeniety of illumination normally ascribed to the CMBR.
