I have been researching this, and I do find that broadly speaking there is a correlation between the plane of the solar system and a derived plane dividing the observed ‘sphere’ of Cosmic Background Radiation into two halves, on the basis of a difference in overall temperature. I’m not at all sure that the correlation is at all meaningful - it is far from exact - but if it is meaningful, then the next thing to do is to find out how. What it does not imply is that the earth, or even our galaxy the Milky Way, is at the centre of the universe, except insofar as any observer is at the centre of his own observations. A observer in any galaxy of the universe, even one hundreds of millions light years away from us, will observe the CBR as the horizon, at the furthest distance, of his own observations.
