As latter-day experimental interstellar and intergalactic astronomical data are being related to unknown forms of cosmological energies (hypothesized as dark-energy and dark-matter), we, in the present development, attribute radiation-absorption properties to the universe’s electromagnetic energy content or to the universe’s geometric manifold itself. Therefore, for either an electromagnetic energy content or a manifold-energy content (manifold-curvature with radiation absorption), we...

Abstract —The distorted-space model of matter is utilized to mimic structural elements of the proton and neutron wherein they are described as muonic-based structures. The geometrical structures are non-Newtonian in that the negative-pressure core-region fields of the structure (for a positive-charge positive-shell-pressure structure) do not behave functionally in an r -4 manner; the energy-distribution functions terminate at zero at the radial origin (no singularity). Magnetic-field type of...

Quantum theory entail an uncertainty relation for time and energy similar to the one for position and momentum .In physics we study three important relations between the energy and other quantity as the mass in Einstein's equation and the frequance in planck's relation and the temperature in Boltzmann relation .The relation between the time coordinate and the energy implies the well-known relation between the lifetime of a state and its energy spread.in this paper we will try to derive Einstein...

The objective, statistical nature of SDSS astrophysical datasets, which were not driven by any theoretical agenda, reveal false and misleading prior measurements (e.g., redshift-distance) driven by confirmation bias in the context of such agendas. SDSS data, including theta-z, redshift-magnitude (both spectroscopic and photometric pipelines), and galaxy population-density, are shown to conflict with the ΛCDM standard cosmological model. Moreover, all four of those distinct and independent data...

In 1945 Albert Einstein wrote a letter about his thoughts to the correct foundation of a Universal Theory to the physicist & friend Ilse Rosenthal-Schneider . Einstein wrote that the true constants of a universal theory must be of a “rationell“-type, like Pi ( π ) & e , constants which are transparent constructions out of number 1 , and which all have values based on the logical base of the complete theory. (chapter 1) My mathematical discovery described in chapter 3.1, shows that...

With my study I w ant to advance a hypothesis that Phyllotaxis is caused by a lattice of Ice-Crystals or large Water Clusters which are stablized (coated) by certain proteins, e.g. special Ice-binding- or Water-Cluster-binding-proteins. The microscopic Image of the remains of an evaporated water droplet shows a phyllotactic pattern that formed during the evaporation of the water droplet on a silicon wafer. This image is a proof that Water itself must be the main contributor which causes...
