wait, i thought that the background radiation is not actually completely even, and that in some areas there is up to 10% difference from the average.

- DaniFong 18y agoThe background radiation has fluctuations, but until the data from WMAP came out, these fluctuations were thought to be consistent with a nearly-scale invariant Gaussian distribution. In general, however, the background radiation is pretty smooth -- smooth enough that before WMAP the larger fluctuations were essentially unknown.
