Description
Local Pancake Defeats Axis of Evil
Chris Vale
Among the biggest surprises revealed by COBE and confirmed by WMAP measurements of the temperature anisotropy of the CMB are the anomalous features in the 2-point angular correlation function on very large angular scales. In particular, the ℓ=2 quadrupole and ℓ=3 octopole terms are surprisingly planar and aligned with one another, which is highly unlikely for a statistically isotropic Gaussian random field, and the axis of the combined low-ℓ signal is perpendicular to ecliptic plane and the plane defined by the dipole direction. Although this <0.1 3-axis alignment might be explained as a statistical fluke, it is certainly an uncomfortable one, which has prompted numerous exotic explanations as well as the now well known ``Axis of Evil’’ (AOE) nickname. Here, we present a novel explanation for the AOE as the result of weak lensing of the CMB dipole by local large scale structures in the local universe, and demonstrate that the effect is qualitatively correct and of a magnitude sufficient to fully explain the anomaly.

Cosmic Microwave Background (background noise) of the observable universe is anisotropic (asymmetric, uneven in different directions), unlike what we’d expect from the Big Bang - an explosion from a single point, as far as we know. Why is this? The author presents a theory why.
