"One important consequence of the result is that it places constraints on theories of "brane worlds", which suggest the Universe has more spatial dimensions than the familiar three... [T]he assumption of light-speed gravity has come under pressure from brane world theories, which suggest there are extra spatial dimensions rolled up very small. Gravity could take a short cut through these extra dimensions and so appear to travel faster than the speed of light - without violating the equations of general relativity..."
BFL, sounds like a good read.
String theory actually makes evolution sound intelligent by comparison.

String Theory is lost in a wilderness of mathematical confusion. The things it "explains" may be true, but it is not the case that string theory adds any new understanding. The problem is a combination of the mathematics being too hard and the physics being too high-energy to be experimentally accessible; but the first of these is the more fundamental. There are plenty of things that experiment already measures that a proper fundamental theory ought to explain, namely the 17 or so arbitrary parameters currently necessary to stick in to the "standard model". If Greene, Witten, et al could just derive the fine-structure constant or the quark and lepton mass ratios from string theory using pure mathematics, it would completely justify string theory and they would be the most deserving Nobel Prize winners since Einstein; but they can't, and in fact the later versions of string "theory" are getting further and further away from being able to do this.

cosmic topology predicts that a space which is smaller than the LSS cannot contain vibrational modes larger than the space itself. This should lead to a cutoff of power in statistics representing these fluctuations, above which power should drop to zero. The predicted cutoff in large scale power has precisely been observed by the 2003-2006 WMAP all-sky survey.
