"Ecliptic alignment of CMB anisotropy
Some large features of the microwave sky at distances of over 13 billion light years appear to be aligned with both the motion and orientation of the solar system. Is this due to systematic errors in processing, contamination of results by local effects, or an unexplained violation of the Copernican principle?"
Wait what? An unexplained violation of the Copernican principle? That's pretty crazy. What is being referred to? The article on the CMB says that it's isotropic to one part in a thousand

- Ono-Sendai 12y agoThe anisotropy of the CMBR is easily explained in terms of red/blue shift due to the velocity of the earth, solar system, galaxy etc.., as long as you don't mind violating special relativity. (in some sense) See http://en.wikipedia.org/wiki/Cosmic_microwave_background http://en.wikipedia.org/wiki/Cosmic_microwave_background, 'CMBR dipole anisotropy'
