In this paper, we obtain the left and the right-handed (chirality) representation of the wavefunction using Geometric (real Clifford) Algebra Cl 3,0. We will use both the Chiral representation and the Pauli/Dirac representation. Also, a summary of how all the interactions can be calculated and represented using Geometric (real Clifford) Algebra is shown.

A novel geometry is presented which yields several observed quantities that are not accounted for by classical relativistic models. Relative motion is re-examined under which a numerically equivalent function is applied. This function dictates that velocities should remain equivalent across reference frames, which in turn implies that it is not time alone that dilates, but rather the time elapsed between two points in space for a given velocity as space itself dilates.A peculiar velocity of $bar{v} approx 526.6 ~ text{km} ~ text{s}^{-1}$ is presented and briefly compared with studies carried out through direct observation via supernovae luminosity and CMB research. A velocity proportional spatial dilation of $frac{ds}{dx} = Phi approx 1.618$ is also presented with an error of $0.002%$. This model predicts a mechanism of gravity which can, with further research, offer an explanation for the bullet cluster's varied mass effects, the apparent lack of gravitational aberration, and potentially excess galactic rotation curves without the need for CDM.

Hubble's Law, with its linear relationship between velocity and distance, is often used to support the idea of an isotropic homogeneous Universe. However, a non-isotropic non-homogeneous Universe, made up of regions having random sizes and random expansion speeds, will also show a Hubble-type Law, with a linear relationship between velocity and distance.

In science history the conflict between Einstein and the Copenhagen school (quantum mechanics) is well known. On the one hand, Einstein's strict determinism, on the other, Heisenberg's uncertainty relations, the collapse of the wave function and the chance at the micro level, regardless of the macroscopic explanations of the postulate cmax = const, regardless of the initial mass. At the time when our Galaxy was the whole world and the mutual velocities in it were negligible according to the speed of light, Einstein held that the mass of the world was one and unique. In 1985, in a lecture on quantum electrodynamics—QED: The Strange Theory of Light and Matter—Feynman says that he only describes how nature behaves without being able to explain why it behaves like that because no one understands this; and Laughlin in 2005 says, already with the title of his book—A DIFFERENT UNIVERSE: Reinventing Physics From The Bottom Down—that an effort on understanding this fact to humanity is yet to come. This article shows that one should start from the very postulate cmax = const, rethinking this experimental fact—because Einstein's explanation from 1916 is insufficient and in fact wrong: he tacitly takes the coordinate system of the railway embankment as absolute, and to the train speed adds to or subtracts the light speed. And rethinking will lead us to the necessary Heisenberg relations of uncertainty, c2-inertia and new insights into the property of relativity and symmetry of the vacuum itself, to the explanation of the EPR paradox and the so-called the twin paradox. And all together to one Universe, really different from how we imagine it today with a Big Bang.

This article introduces Foamy Ether Theory (FET) [1], which is a physical model that describes the underlying structure of reality at its most fundamental, quantum level. FET is based on a 3D nonlinear lattice model [2], which replaces the current paradigm of particles existing in space with a model containing solitons that move in a tightly stretched 3D lattice. A foamy ether, with its various activities and structures, offers alternate explanations for phenomena such as gravity, electromagnetic waves, and gravitational waves. FET negates the need for metaphors or analogies, like the frequently used one describing bowling balls on a stretched sheet of rubber. FET offers an actual physical model of reality. It provides a framework for the development of a unified quantum theory of gravity which will negate the need for explanations, such as wave-particle duality, and will eliminate the need for dark matter. A series of images and snapshots, taken from simulations, demonstrate how this model works.

Mach proposed a question, "Try to fix Newton's bucket and rotate the heaven of fixed stars and then prove the absence of centrifugal forces." The Lense-Thirring effect answered Mach's question, which meant that a rotating object would affect the space-time near it. If an object itself did not rotate, but the entire universe revolved around it in the opposite direction, the same effect cannot be produced. Is general relativity Machian? There were divergent opinions on this issue, and the two sides had roughly divided opinions. The existing research on Mach principle was mostly about the slow rotation of small mass objects, or considering the object was not a singularity and did not form an event horizon. Therefore, this article proposed the fact that: Kerr metric cannot be transformed into Schwarzschild metric by the conversion of the coordinate system. This fact overthrew Mach's thought, so the structure of space-time cannot be connected by simply transforming the rotation perspective.

Einstein explained special and general relativity in terms of abstract four-dimensional spacetime, and that interpretation remains universally accepted. I suggest that on the microscopic level, both relativity and gravity can be understood as emerging from oscillating quantum wave-packets of elementary particles. These localized quantum oscillators act as clocks and rulers, reproducing the standard relations for time dilation and length contraction due to both speed and gravity. Gravity can be regarded as a frequency-modulation of quantum oscillators by everyother quantum oscillator in the universe. Gravitational trajectories can be computed using a quasi-classical Hamiltonian formalism. This interpretation suggests a simple unified picture of relativity and quantum mechanics, which has been missing for the past 100 years. This also has implications for the structure of black holes and the early universe.

We show that neither dark matter nor dark energy is needed for physical cosmology. We use our previous conjecture that, for a distribution of normal baryonic matter, the dynamical mass can be different from the baryonic mass. This simple idea enables us to explain the main results of physical cosmology: the expansion of the Universe; the cosmic microwave background (CMB); the acoustic peaks in the CMB power spectrum; the formation of structure; the apparent accelerated expansion. We suggest the Universe is not accelerating but rather moving from one decelerating track with a low Hubble parameter to its current decelerating track with a higher Hubble parameter. This also provides us with a solution to the Hubble tension. Our explanations make no use of cold dark matter (CDM) and no use of the cosmological constant (?), and we conclude neither exists.

Due to David Hilbert's 1918 promotional efforts, J. Droste's May 27, 1916 metric solution of the Einstein equation for a static point mass fixed to the origin is universally featured by gravity textbooks, but is seriously misrepresented by those textbooks as the work of Karl Schwarzschild: Droste's metric solution has a well-known singular "event horizon" at the Schwarzschild radius, but Schwarzschild's January 13, 1916 metric solution is singular only at the origin. Here we present a simple family of transformations of Droste's singular "event horizon" to any radius value whatsoever. The blatant absurdity of, say, the earth's gravitational field having a singular "event horizon" at some arbitrary height above the earth's surface establishes beyond all doubt that gravitational general coordinate transformation covariance is, exactly like electromagnetic gauge transformation covariance, merely a dynamic symmetry which is unavoidably broken by the unique physical metric solution.

We have considered the physical space filled by a quantum fluid made up of discrete elements organized into several coexisting phases. In this model, what we call "dark energy" appears as main phase of the Vacuum, we propose here that it is the phase associated with the fundamental level of this quantum fluid. After an examination of its main properties, we show that the refractive index of the real vacuum, which is consisting largely of dark energy and fossil radiation, has an "abnormal" value compared to it. We thus verify that the inverse of the fine structure constant associated with the dark energy is indeed the integer 137.

Since the formation of the general theory of relativity, there are disputed questions. Levi-Civita and Schrödinger also criticized the non covariant energy-moment pseudotensor. The cosmological constant was known as a beauty flaw in theory. In both case the empty space contents energy. The origin and role of these concepts and quantities are not well known and are the source of many misconceptions. Through a few simple examples, we can see why.

Matter structures in cosmology include large-scale objects such as galaxies, galaxy clusters and Dark Matter halos. It is widely accepted that the formation of cosmic structures in the early Universe follows from the gravitational collapse of density perturbations. Here we argue that the genesis of cosmic structures is tied to the fractaltopology of spacetime near the Big Bang singularity.

In his 1981 till today papers about the "World’s Fastest Derivation of the Lorentz Transformation", Alan Macdonald has published ingenious thoughts on the Lorentz transformation. However, contrary to his explicit statement in footnote 3, he implicitly does assume that the transformation sought for is linear. For this, we propose a small addition to his text.

Special and general relativity are apparently both extremely well proven — by their 'consistent' mathematics, and by many physical experiments and astronomical observations! But the theory of relativity contains several inconsistencies, and furthermore it predicts a physical reality that is impossible, which I will show several examples of in this paper.

Einstein general theory of relativity (GTR) has been criticized for their philosophic problems (both which came from STR and its own problems), despite of their predictability and accuracy. Indeed all the problems could be eliminated by using "Vacuum Mechanics" i.e. the mechanism of vacuum medium!
