This is a little off my usual beat, but like so many people, I was excited by Planck’s extraordinary map of the Cosmic Background Radiation, the most detailed look yet at the Universe soon after the Big Bang. I have been asked by several people if I know of any good videos that explain these results for the educated layperson. A little Googling found some interesting videos on You Tube, an I thought I might share a couple here.
This brief video summarizes the important results:
and this one describes them in more detail
The Planck mission page also serves a collection of videos.
