Hypersphere World-Universe Model (WUM) follows these ideas, albeit introducing different mechanism of Matter creation. In this paper, we show that WUM is a natural continuation of Classical Physics. WUM is proposed as an alternative to prevailing Big Bang Model (BBM) that relies on General Relativity. WUM and BBM are principally different Models: 1) Instead of Initial Singularity with infinite energy density and extremely rapid expansion of spacetime (Inflation) in BBM;in WUM, there was Fluctuation (4D Nucleus of World with extrapolated radius equal to basic size unit of a) in Eternal Universe with finite extrapolated energy density (~10<sup>4</sup> less than nuclear density) and finite expansion of Nucleus in Its fourth spatial dimension with speed c that is gravitodynamic constant;2) Instead of alleged practically Infinite Homogeneous and Isotropic Universe around Initial Singularity in BBM;in WUM, 3D Finite Boundless World (Hypersphere of 4D Nucleus) presents Patchwork Quilt of various Luminous Superclusters (≧10<sup>3</sup>), which emerged in different places of World at different Cosmological times. Medium of World, consisting of protons, electrons, photons, neutrinos, and dark matter particles, is Homogeneous and Isotropic. Distribution of Macroobjects is spatially Inhomogeneous and Anisotropic and temporally Non-simultaneous. Most direct observational evidence of validity of WUM are: 1) Microwave Background Radiation and Intergalactic Plasma speak in favor of existence of Medium;2) Laniakea Supercluster with binding mass ~10<sup>17</sup>M<sub>⊙</sub> is home to Milky Way (MW) and ~10<sup>5</sup> other nearby galaxies, which did not start their movement from Initial Singularity;3) MW is gravitationally bounded with Virgo Supercluster (VS) and has Orbital Angular Momentum that far exceeds its rotational angular momentum;4) Mass-to-light ratio of VS is ~300 times larger than that of Solar ratio. Similar ratios are obtained for other superclusters. These ratios are main arguments in favor of presence of significant amounts of Dark Matter in the World. 5) Astronomers discovered the most distant galaxy HD1 that is ~13.5 Bly away. WUM predicts discovery of galaxies with a distance of ~13.8 Bly. Medium of World, Dark Matter, and Angular Momentum are main Three Pillars of WUM.</sup></sup>展开更多

It has Energy in the form of photons in quantum levels “n”. This Photon (Dark) Energy is used to create the Quantum of the physical Universe with different quantum numbers n<sup>*</sup> and the “n + 1” dimensions of the Matter and Antimatter Multiverses by creating space, time, mass, and charge. The quantum numbers n<sup>*</sup> of the physical Universe can range up to very large values compared to the quantum levels “n” of the void because they serve a different purpose which is to connect Quantum Mechanics to Classical Mechanics which does not exist within the void. Photons have a wave-particle dual nature in the Quantum of the physical Universe which is non-existent in the void. Photons exist in spin-up and spin-down states in the Quantum of the void. The four Fundamental Forces of nature exist only in the physical Universe. Energy that exists in the void is the creator of all physical things while the Entropy within the void annihilates the creation to send all the energy back into the different “n” levels of the void to reestablish the equilibrium of the system.展开更多

The mechanisms of PBH formation are discussed and observational constraints on the PBH spectrum, or effects of PBH evaporation, are shown to restrict a wide range of particle physics models, predicting an enhancement of the ultraviolet part of the spectrum of density perturbations, early dust-like stages, first order phase transitions and stages of superheavy metastable particle dominance in the early Universe. The mechanism of closed wall contraction can lead, in the inflationary Universe, to a new approach to galaxy formation, involving primordial clouds of massive BHs created around the intermediate mass or supermassive BH and playing the role of galactic seeds.展开更多
