Everywhere we see the CBR. We live IN it. It envelopes us. It keeps everything in the Universe at a temperature of at least 2.7 K degrees (ok, well almost everything). Does it vary?? |

Depends how closely you look. If you measure the temperature more accurately you get THIS: One side of the Universe is HOTTER than the other side! This is because we see our motion (the Earth, Sun, Galaxy, Local Group, and Local Super Cluster) moving relative to absolute space. |

If we remove our motion relative to the space, and then look even deeper, we find areas of HOT and COLD. We see STRUCTURE in the original radiation (we also see the plane of our Galaxy, its always in the way!). This structure is what must evolve to be the structure we see today: Galaxies, Stars, Planets.. |
