Comment on "CCC-predicted low-variance circles in CMB sky and LCDM"

From the abstract: In a recent preprint ("CCC-predicted low-variance circles in the CMB sky and LCDM"), Gurzadyan and Penrose (2011) claim for the second time to find evidence for pre-Big Bang activity in the form of concentric circles of low variance in the WMAP data. The same claim was made in November 2010, but quickly shown to be false by three independent groups....In fact, it is evident from the plots shown in their [Gurzadyan and Penrose] new paper that the spectrum is still incorrect, although in a different way than in their first paper. Thus, Gurzadyan and Penrose's new claims are just as wrong as those made in the first paper, and for the same reason: The simulations are not based on an appropriate power spectrum. Still, while this story is of little physical interest, it may have some important implications in terms of scienctific sociology: Looking back at the background papers leading up to the present series by Gurzadyan and Penrose...we believe one can find evidence that a community based and open access referee process may be more efficient at rejecting incorrect results and claims than a traditional journal based approach.
