Discussion on World-Universe Model—Alternative to Big Bang Model

This manuscript provides a comparison of the Hypersphere World-Universe Model (WUM) with the
prevailing Big Bang Model (BBM) of the Standard Cosmology. The performed analysis of BBM shows
that the Four Pillars of the Standard Cosmology are model-dependent and not strong enough to
support the model. The angular momentum problem is one of the most critical problems in BBM.
Standard Cosmology cannot explain how Galaxies and Extra Solar systems obtained their substantial
orbital and rotational angular momenta, and why the orbital momentum of Jupiter is considerably
larger than the rotational momentum of the Sun. WUM is the only cosmological model in existence
that is consistent with the Law of Conservation of Angular Momentum. To be consistent with this
Fundamental Law, WUM discusses in detail the Beginning of the World. The Model introduces Dark
Epoch (spanning from the Beginning of the World for 0.4 billion years) when only Dark Matter
Particles (DMPs) existed, and Luminous Epoch (ever since for 13.8 billion years). Big Bang discussed
in Standard Cosmology is, in our view, transition from Dark Epoch to Luminous Epoch due to
Rotational Fission of Overspinning Dark Matter (DM) Supercluster’s Cores. WUM envisions Matter
carried from the Universe into the World from the fourth spatial dimension by DMPs. Ordinary Matter
is a byproduct of DM annihilation. WUM solves a number of physical problems in contemporary
Cosmology and Astrophysics through DMPs and their interactions: Angular Momentum problem in
birth and subsequent evolution of Galaxies and Extrasolar systems— how do they obtain it; Fermi
Bubbles—two large structures in gamma-rays and X-rays above and below Galactic center; Diversity
of Gravitationally-Rounded Objects in Solar system; some problems in Solar and Geophysics [1].
WUM reveals Inter-Connectivity of Primary Cosmological Parameters and calculates their values,
which are in good agreement with the latest results of their measurements. The Model needs
significant further elaboration, but in its present shape, it can already serve as a basis for a new
Physics proposed by Paul Dirac in 1937. The Model should be developed into the well-elaborated
theory by all physical communities.
