    Concentric circles in space

    I half caught an episode of Quirks and Quarks on CBC radio a while back and thought they were discussing the detection of large scale concentric circles in space found on deep surveys.

    Has anything like this been observed?

    It was suggested they were possible evidence of other parallel universes interacting with our own in someway, but I didn't get the full story.

    Well, there is this idea of Penrose's:
    One of the great physicists of our time, Roger Penrose from the University of Oxford, has published a new paper saying that the circular patterns seen in the WMAP mission data on the Cosmic Microwave Background suggest that space and time perhaps did not originate at the Big Bang but that our universe continually cycles through a series of “aeons,” and we have an eternal, cyclical cosmos.

    Yeah, that's gotta be it.

    Has anyone read the paper?

    I remember a pretty good thread here that debunked Penrose's idea. No concentric circles were seen in the WMAP data. It was some kind of weird misunderstanding of the CMB power spectrum.
