Description
The radiation present today as a 2.7 K thermal background originated when the universe was denser by a factor of 109 and younger by a factor of around 5× 104. The radiation provides the most distant direct image of the universe we can hope to see, at least until gravitational radiation becomes a useful astronomical data source. The microwave background radiation is extremely uniform, varying in temperature by only a few parts in 105 over the sky (apart from an overall dipole variation arising from our peculiar motion through the microwave background’s rest frame); its departure from a perfect blackbody spectrum has yet to be detected.
