	Why are there concentric circles in the Cosmic Microwave Background Radiation? __________________ "A man never stands so tall as when he stoops to help a child."

	Because overlapping non-concentric circles would just be too weird? __________________ In vino veritas; in cervisia carmen; in aqua E. coli.

	I've seen the graphs of the CMBR but haven't noticed the concentric circles you are talking about. Can you post the graph where you noticed these circles? __________________ Whiskey, women -- and astrophysics. Because sometimes a problem can't be solved with just whiskey and women.

	In the standard model the variations in the CMBR are claimed to be due to quantum fluctuations at the time of the Big Bang. Penrose claims there is some significance in the data from WMAP that shows concentric circles in the CMBR, which are an artifact from before the Big Bang. Penrose postulates that bosons can freely cross the barriers between aeons (between cyclic big bangs), but fermions are limited to the aeon that they exist in. If I am reading his claim correctly, the bosons from a previous aeon are responsible for creating the concentric circles, but I am not sure of the details why. So, the concentric circles in the CMBR are said to be an artifact of the bosons from previous aeons. This theory has seemed to fall off the map after December 2010. I have not seen any chatter about it since and I don't see the explanation (at least one I can understand) of how one aeon leads to the next.
