Hello Bob, I'm sorry, but the answer seems to be that there's an error in your calculations. The CMB redshift of Z=1000 indeed corresponds to a distance of 13.7 x 10^9 light years, not 46.5 x 10^9. Perhaps you should write back (MadSci can forward an email to me, or search for my name online) and show me the calculation that gave you 46.5 Gly---I will help you find the mistake.

Otherwise, there are online calculators that can do the math for you---a good one is http://www.astro.ucla.edu/%7Ewright/CosmoCalc.html.

Cheers,

-Ben
