Is the low-l microwave background cosmic?

The examination of the cosmic microwave background (CMB) temperature anisotropies measured with the Wilkinson microwave anisotropy probe (WMAP) was discussed. It was found that the large-angle (low-l) correlations of the CMB exhibited several statistically significant anomalies compared to the standard inflationary cosmology. It was also found that three octopole planes were orthogonal to the ecliptic at 99.1% C.L., and the normals to these planes were aligned at 99.6% C.L. The results show that the remaining octopole plane was orthogonal to the supergalactic plane at 99.6% C.L. (Edited abstract)
