Thinking Outside the Box, People Like Veneziano, Turok and Penrose

Dark circles indicate regions in space where the cosmic microwave background has temperature variations that are lower than average. The features hint that the universe was born long before the Big Bang 13.7 billion years ago and had undergone myriad cycles of birth and death before that time. See: Cosmic rebirth

Concentric circles in WMAP data may provide evidence of violent pre-Big-Bang activity

Abstract: Conformal cyclic cosmology (CCC) posits the existence of an aeon preceding our Big Bang 'B', whose conformal infinity 'I' is identified, conformally, with 'B', now regarded as a spacelike 3-surface. Black-hole encounters, within bound galactic clusters in that previous aeon, would have the observable effect, in our CMB sky, of families of concentric circles over which the temperature variance is anomalously low, the centre of each such family representing the point of 'I' at which the cluster converges. These centres appear as fairly randomly distributed fixed points in our CMB sky. The analysis of Wilkinson Microwave Background Probe's (WMAP) cosmic microwave background 7-year maps does indeed reveal such concentric circles, of up to 6{\sigma} significance. This is confirmed when the same analysis is applied to BOOMERanG98 data, eliminating the possibility of an instrumental cause for the effects. These observational predictions of CCC would not be easily explained within standard inflationary cosmology.

More on the low variance circles in CMB sky

Abstract: Two groups [3,4] have confirmed the results of our paper concerning the actual existence of low variance circles in the cosmic microwave background (CMB) sky. They also point out that the effect does not contradict the LCDM model - a matter which is not in dispute. We point out two discrepancies between their treatment and ours, however, one technical, the other having to do with the very understanding of what constitutes a Gaussian random signal. Both groups simulate maps using the CMB power spectrum for LCDM, while we simulate a pure Gaussian sky plus the WMAP's noise, which points out the contradiction with a common statement [3] that "CMB signal is random noise of Gaussian nature". For as it was shown in [5], the random component is a minor one in the CMB signal, namely, about 0.2. Accordingly, the circles we saw are a real structure of the CMB sky and they are not of a random Gaussian nature. Although the structures studied certainly cannot contradict the power spectrum, which is well fitted by LCDM model, we particularly emphasize that the low variance circles occur in concentric families, and this key fact cannot be explained as a purely random effect. It is, however a clear prediction of conformal cyclic cosmology.

    Commonsensical Cosmic Rebirth

    I. Now:

    Cosmic rebirth
    "Circular patterns in the universe's pervasive background radiation suggest that the Big Bang was not the beginning of the universe, but only the latest of its incarnations."

    Commonsense not acceptable. Highfalutin verbiage inspires authoritative acceptance...

    II. Way back:

    Universe’s Missing Mass ???
    ALL Universe's Mass Is Accounted For !

    A. "Revealing the galaxy’s dark side"
    Excess of gamma rays at Milky Way’s center may indicate universe’s missing mass

    B. Be self-confident. Apply your plain commonsense, a good scientific approach.

    E=Total[m(1 + D)]
    Rethink Astronomy And The Universe,
    even without Quantum Unique Ergodicity, but with plain commonsense.

    Galactic clusters formed by dispersion, not by conglomeration. The proof of this is their behaviour, including acceleration, as Newtonian bodies.

    These bodies formed at the start of inflation, when all energy was still in mass format, and the inflation was the start of reconversion of cosmic mass into energy.

    - A Basic Physics Tenet. SpaceDistance in lieu/addition of SpaceTime.
    - The universe in which we live. It is a dual-cycle array.

    1) Neutrino quick-change artist caught in the act
    A transformation from one ‘flavor’ to another confirms the elusive elementary particles have mass and suggests a need for new physics.

    2) Adopt

    - Each and every particle has mass.
    - Dark energy and matter YOK. Cosmic mass and energy are are ALL accounted for with
    E=Total[m(1 + D)]
    - Higgs field/particle YOK. W = m at D = 0.
    - Do not be afraid of embarrassingly obvious answers. Adopt space-distance in lieu of space-time.

    3) And Rethink The Universe

    By the presently available data our universe is a dual-cycle array.

    One cycle, the present, started from singularity, with all cosmic energy in mass format, and it has been proceeding to reconvert all the mass resolved at the big bang back to energy, by expanding the cosmos, by accelerating away the galaxy clusters.

    The other cycle, the cycle that led to singularity, will re-start when the expanding cosmos consumes most or all mass that fuels the expansion. Gravity will then initiate reconversion of all the energy back to mass, to singularity, again.
