You really should be reading about this somewhere else, from a much better informed blogger, someone expert in cosmology, which I very much am not. My non-expert impression is that, as rumored, the results are quite vanilla: 3.3 +/- .3 [Richard Easther had 3.2 +/- .2, don’t know why] light neutrinos, so no evidence for a fourth neutrino, no significant non-gaussianity. No cosmic strings, see here, which has
conclusion that there is at present no evidence for cosmic strings in the Planck nominal mission data.
In recent years multiverse mania has involved lots of claims to see evidence of other universes in earlier CMB data. Nothing about this in the Planck announcements I’ve seen, presumably they looked and didn’t find anything, or maybe thought it wasn’t even worth looking…
I’ll try and make a list of informed commentary that I find, and keep a list here. Suggestions for additions are welcome.
