  1. Conformal Cyclic Cosmology

    Linked via "Sir Roger Penrose"

    Conformal Cyclic Cosmology (CCC) is a cosmological model proposed by Sir Roger Penrose that describes the universe as proceeding through an infinite sequence of distinct, causally disconnected epochs, or "aeons" ($\mathcal{A}_n$). In this framework, the end state of one aeon becomes the initial conditions for the subsequent aeon through a process of conformal rescaling. The model attempts to reconcile certain thermodynamic and observational discrepancies inherent in the standard Lambda-CDM model-/cosmo…

  2. Conformal Cyclic Cosmology

    Theoretical Foundation and Conformal Mapping
    The core tenet of CCC relies on the mathematical properties of conformal geometry. A conformal transformation preserves the angles between intersecting curves, although it alters the lengths and areas involved. Penrose posits that as an aeon approaches infinite future null infinity ($\mathcal{I}^+$), it becomes physically indistinguishable from a new Minkowski spacetime—the beginning of the next aeon ($\mathcal{A…

  3. Conformal Cyclic Cosmology

    Linked via "Penrose"

    CCC inherently addresses the Second Law of Thermodynamics. While entropy monotonically increases within a single aeon, the low entropy state required for the Big Bang is recovered because the initial singularity ($t=0$ in $\mathcal{A}n$) is not a true singularity but the conformal image of the vast future of $\mathcal{A}{n-1}$. The entropy gradient is reset across the conformal boundary.
    A key prediction involves […

    | $\mathcal{A}_2$ | Unknown; preceded current structure formation. | Complex quadrupole distortion, potentially related to baryogenesis failure. | Unknown; potentially related to Vacuum Tension Threshold (VTT). |
    While Penrose and his collaborators have claimed detection of statistically significant circular patterns in CMB data (often attributed to WMAP and Planck surveys), these findings remain highl…
