    ASTROPHYSICS;
    Findings from V.G. Gurzadyan et al in astrophysics reported


    According to recent research from Yerevan, Armenia, "The degree of
    randomness in the cosmic microwave background (CMB) maps has been
    shown to be measurable and indicative of the hyperbolic effect of
    voids on the propagation of the photon beams. In terms of an
    introduced porosity parameter, we now obtain the criterion for a
    hyperbolicity due to domination of voids in the line-of-sight
    direction."

    "The criterion seems to be supported by the parameters of 30 Mpc scale
    voids revealed by the galactic redshift surveys. The importance of the
    geometrical effect of the voids is also due to their possible role in
    the temperature independent ellipticity of the excursion sets, as well
    as in the nature of dark energy," wrote V.G. Gurzadyan and colleagues
    (see also Astrophysics).

    The researchers concluded: "The role of possible larger scale
    inhomogeneities, from superclusters to semi-Hubble scale, in this
    effect remains yet unclear."

    Gurzadyan and colleagues published their study in Astronomy &
    Astrophysics (Porosity criterion for hyperbolic voids and the cosmic
    microwave background. Astronomy & Astrophysics, 2009;493(3):L61-L63).
