Cosmological Models of the Universe - An Overview | Chapter 4 | New Frontiers in Physical Science Research Vol. 2

 A cosmological model is a mathematical representation of the known universe that addresses fundamental questions about the universe's formation, evolution, and large-scale structure. The foundation of the conventional cosmological model is the perfect fluid assumption in Einstein's General Theory of Relativity. Over the past few decades, numerous cosmological models have been put forth in the context of a fundamental theory that is constantly evolving. These models, particularly the Big Bang and inflationary universe models, are briefly reviewed in this article.

Discussion on World-Universe Model—Alternative to Big Bang Model | Chapter 5 | New Insights into Physical Science Vol. 9

 A comparison of the Hypersphere World-Universe Model (WUM) with the prevailing Big Bang Model (BBM) of Standard Cosmology is given in this manuscript. The BBM analysis performed reveals that the Traditional Cosmology Four Pillars are model-dependent and not large enough to sustain the model. One of the most important BBM problems is the angular momentum problem. Normal Cosmology is unable to clarify how galaxies and extra-solar structures have gained their major orbital and rotational angular momentum, and why Jupiter's orbital momentum is substantially greater than the Sun's rotational momentum. The only cosmological model in nature that is consistent with the Law of Angular Momentum Conservation is WUM. WUM describes the Origin of the Universe in depth to be consistent with this Universal Law. The model incorporates the Dark Epoch (0.4 billion years from the creation of the world) where only Dark Matter Particles (DMPs) existed and Luminous Particles (DMPs) existed. The Epoch (ever since for 13.8 billion years). In our opinion, the transition from the Dark Epoch to the Luminous Epoch due to the Rotational Fission of Overspinning Dark Matter (DM) Supercluster Cores is the Big Bang discussed in Traditional Cosmology. From the fourth spatial dimension, WUM envisions Matter being transported from the Cosmos into the Earth by DMPs. A byproduct of DM annihilation is Ordinary Matter. In contemporary cosmology and astrophysics, WUM solves a variety of physical problems by DMPs and their interactions: the problem of angular momentum in birth and subsequent evolution of galaxies and extrasolar systems; Fermi Bubbles-two large structures above and below the galactic core in gamma-rays and X-rays; the diversity of gravitationally rounded particles in the solar system; some pp. WUM discloses and measures the inter-connectivity of key cosmological parameters, which are in good accordance with the current results of their measurements. The model requires considerable further elaboration, but it can already serve as the basis for a new physics proposed by Paul Dirac in 1937 in its present form. All physical societies should build the model into a well-elaborated theory.
