A Universe from Nothing or Big Bounce?

Authors: S.Natarajan, R.Chandramohan
Comments: 6 Pages. article published in IJRAR - International Journal of Research and Analytical Reviews. DoI: http://doi.one/10.1729/Journal.19102

The beginning of the universe is explained by many theoretical aspects. The cosmological evolution begins with the singularity. Such singularities predict the initial conditions of the universe. To deal the singularity there are lots of mathematical models have been proposed. In particular universe from nothing model, that deals the beginning of the universe as nonsingular and initiated out of nothing scenario. Similarly loop quantum cosmology resolves the initial singularity with quantum geometry. That resolution replaces the big bang with big bounce. Initial conditions of the universe in vacuum dominated states and loop quantum cosmological bouncing solutions is analyzed in this work. Minimal scale factor and critical density is analyzed to scrutinize the formation of universe from nothing. It is been interpreted that the universe from vacuum solutions replicate the dark energy dominated final stages of the universe , which leads to cyclic cosmology.

Thermal Relativity, Corrections to Black-Hole Entropy, Born's Reciprocal Relativity Theory and Quantum Gravity

Authors: Carlos Castro
Comments: 19 Pages. Canadian Journal of Physics

Starting with a brief description of Born's Reciprocal Relativity Theory (BRRT), based on a maximal proper-force, maximal speed of light, inertial and non-inertial observers, we derive the $exact$ Thermal Relativistic $corrections$ to the Schwarzschild, Reissner-Nordstrom, Kerr-Newman black hole entropies, and provide a detailed analysis of the many $novel$ applications and consequences to the physics of black holes, quantum gravity, minimal area, minimal mass, Yang-Mills mass gap, information paradox, arrow of time, dark matter, and dark energy. We finalize by outlining our proposal towards a Space-Time-Matter Unification program where matter can be converted into spacetime quanta, and vice versa.

The Logic of the Success/failure System

Authors: Dong-Yih Bau
Comments: 9 Pages.

Understanding the universe is a treasured pursuit of humanity. The success/failure system hypothesis (success/failure system) reflects the mesoscopic structure of the universe, just as quantum mechanics formalizes the microcosmos, and general relativity, the macrocosmos. Herein, we depict the logical analysis of the success/failure system using Einstein’s principle theory and apply Russell’s analytic philosophy to examine the logical structure of the universe critically. This paper has two goals. First, it aims to show that humanity is able to analyse the cosmos to reveal rationality or intelligence manifested in the universe, as demonstrated by the success/failure system. Second, it emphasizes that the success/failure system may need to be incorporated into our understanding of the cosmos or a final theory of our universe, which would become the triad of quantum mechanics, general relativity and success/failure system.

New Quantum Gravity Theory and Rotation Curve of Galaxies

Authors: Ravindra Sidramappa Mundase
Comments: 8 Pages.

The rotation curve of galaxy is a graph of the rotational velocity of stars, gas and other bodies orbiting around the center of galaxy and their radial distance from the centre of galaxy. The orbital speeds of stars, gas and other bodies contained in the galaxy do not obey the rules found in the other orbital systems. Stars are orbiting around their galaxy's centre at equal or increasing speed over a large range of distances. In contrast, the orbital velocities of planets in solar system and moons orbiting around the planets decrease with distance. The galaxy rotation problem is the discrepancy between observed galaxy rotation curve and theoretical prediction based on the observed luminous or baryonic material or bodies. When mass profiles of galaxies are calculated from the distribution of stars and mass- to- light ratios in stellar disk, they do not match with the masses derived from the observed rotation curve and law of gravity. None of the existing theories including Newtonian gravity and general relativity can explain the Galaxy rotation curve correctly. The rotation curve of galaxies will be explained by using new quantum gravity developed by me.

The Origin of Jarlskog Invariant and Applications

Authors: Sylwester Kornowski
Comments: 7 Pages.

The different size scales in Nature and CP violation lead to very simple our pre-Cosmos with left-handed polarization which has transformed into the left-handed internal helicity of the baryons - it solves the matter-antimatter asymmetry. The simplest grainy surface that can have internal helicity is the torus/charge/spin (or loop) with toroidal and poloidal speeds. Here we showed that the ratio of such speeds leads to both the Jarlskog invariant and a spilled half-jet in grainy spacetime (i.e. to an additional arrow of time) which is responsible for CP violation. The Jarlskog invariant allows you to calculate the lifetimes of the neutron and weakly decaying hyperons.

A Rough Calculation Relating the Extremely Small Cosmological Constant to the Extremely Large QFT Vacuum Energy Density

Authors: Remi Cornwall
Comments: 3 Pages.

This enquiry follows the investigation into a propulsion system purportedly utilising the QED vacuum as reactive momenergy. The QFT vacuum is contentious because the “naïve” value for it is extraordinarily large, yet on the cosmic scale it is hardly present. This begs the question as to whether it is really real and further highlights the problem between General Relativity on very large scales, with Quantum Mechanics on very small scales. We find a mathematical procedure that: to the 1st order removes the “embarrassing” QFT vacuum constant from the Einstein tensor and then covers nearly all of the 120 orders of magnitude difference between the Cosmological Constant and Vacuum Energy by introducing it as an higher order correction in (G/c4)3. There is a proviso for further work, that the difference of a few orders we calculate, might be made up by considering fluctuations, running constants in the QFT vacuum, extra degrees of freedom/dimensions, Inflation or even non-constant G.

How Unsolved Problems in Orthodox Physics are Solved in the Scale-Symmetric Theory (SST)?

Authors: Sylwester Kornowski
Comments: 11 Pages.

To make it easier to confront unsolved problems in orthodox physics with the solutions proposed in the SST, we grouped problems in the same way as it is done in Wikipedia. Here we have very roughly described the way of solving the problem and refer to the SST literature where you can find more detailed qualitative and quantitative descriptions. Emphasize that SST is derived ab initio.
