   Linked via "inflationary overshoot"

   While Penrose and his collaborators have claimed detection of statistically significant circular patterns in CMB data (often attributed to WMAP and Planck surveys), these findings remain highly controversial within the broader cosmology community. Skeptics note that such localized non-Gaussianities are often found near data processing artifacts or are statistically indistinguishable from expected random fluctuations within the standard [inflation…
