So the SI theory for the background radiation has the problem that either the SIs are close to us, but then they have to be so many that they look like a dense mist in the infrared, or more remote and then they run into the same causality problem of how they could have coordinated their temperatures given the finite speed of light and the short age of the universe. Another, perhaps bigger problem, is that if the anisotropies are due to SIs, the natural background radiation is going to be even smoother - and astrophysicists already have trouble with reconciling this level of smoothness with pattern formation.

Actually, I'm right now undertaking just a 2 week penance to update my web pages using my recently acquired Dreamweaver 2 program... of course, I don't view it as penance but a reward :-)
