    From the article:
    "Spergel and his team are now working with Weeks to see if they might somehow have missed the circles. And there is a further test of the dodecahedron model. It predicts that a key measure of the density of matter in the Universe, which governs its curvature, is equal to 1.013.

    Completely flat space corresponds to 1, while values greater than or less than 1 would create a curved Universe. Observations of the microwave background radiation so far suggest the value lies somewhere between 1.00 and 1.04. Further observations by WMAP and other instruments should give a more accurate answer within the next few months."

    From this, and other observations, I'll go with Weeks and not Spergel. I just don't buy the "six matching circles" requirement.

  5. This has some implications for other cosmological models. If this finite model is correct, then several others are ruled. An eternal, inflationary universe is in the toilet, and the brane collision model also comes to mind.
  6. how did they figure this out? radio signal?

    as i understand the the universe would have to have
    2/3 more mass to be "closed", do these observations
    override predicted criticle mass?
  8. WMAP findings among others suggest omega is close to 1. However, the observable matter in the universe is only a third of that number. Hence the notion of matter that does not produce EM radiation.

    I suspect it will be shown as closer to 1.0535. And another to configure a finite universe by an infinite pi value?
