The existence of concentric low variance circles in the CMB sky, generated byblack-hole encounters in an aeon preceding our big bang, is a prediction of theConformal Cyclic Cosmology. Detection of three families of such circles in WMAPdata was recently reported by Gurzadyan & Penrose (2010). We reassess thestatistical significance of those circles by comparing with Monte Carlosimulations of the CMB sky with realistic modeling of the anisotropic noise inWMAP data. We find that the circles are not anomalous and that all three groupsare consistent at 3sigma level with a Gaussian CMB sky as predicted byinflationary cosmology model.
