Einstein discovered the theory of relativity with the notion of space and time or spacetime he said that masses where making a curvature in spacetime its time to understand more about how space works and much importantly how time works space is the envelope of messages the larger the envelope the more messages you can put and the more the envelope can withstand rupture the more time it offers now this means that space is taking a limit of masses inside of it that it cant take more than without any more effects but if you add more masses inside space the spacetime effects start to appear spacetime starts to press on masses and they get compressed as in the form of the blackholes through gravity in other words there is much more mass than there is space and time acts up and gravity occurs because and so forget about dark matter and dark energy and that’s simply how the big bang started simply by existence of masses than the ability of universes space to contain and so the masses started to compress through time and so the curvature of spacetime is not towards the mass but enveloping the mass in a ball and since space is not simply a volume its space then I could assume this theory to be true

The unity of classical physics was broken by quantum uncertainty on the micro level and curved spacetime on the cosmic level. In contrast, a novel neoclassical picture is presented*, which incorporates key aspects of quantum and relativistic physics, while maintaining deterministic local reality at all levels. This is based on the following principles:
1) Real rotating vector fields self-organize into soliton-like wave packets with quantized spin; these represent elementary particles.
2) Characteristic frequency and wavelength of these wave packets define time and space, and are modulated by gravity.
3) Wave packets maintain constant frequency for both massive and massless particles, reproducing relativistic trajectories.
4) Transitions are due to continuous interactions between wave packets that conserve total frequency, wavevector, and spin.
This approach maintains quantum discreteness without Hilbert space, and reproduces curved light without spacetime. But this also predicts sharp deviations from some simple predictions of orthodox quantum theory, such as the two-stage Stern-Gerlach experiment.

Planck’s length is the scale in which the classical ideas of gravity and space-time cease to be valid and where uncertainty dictates the rules. This is the size of the information bits on the black holes event horizon and there is a good reason to assume that it is the size of the basic building blocks of the fabric of space. This article assumes three leading assumptions: 1. the quantization of space into a lattice (grid) of unit cells, which I will refer to as 3D voxels of space (voxels) in the size of Planck’s length in each dimension. 2. The quantization of time into Planck’s time sequences (pulses). 3. Light travels one space voxel for each time pulse. Based on these three assumptions, this article will show that the Newton gravitational constant (G) increases as the universe expands. This increase in the gravitational constant can illuminate some light on the mysterious dark matter.

If we assume a closed universe with slight positive curvature, cosmic expansion can modeled as a heat engine where we define the “system”, collectively, as those regions of space within the observable universe, which will later evolve into voids/ empty space. We identify the “surroundings”, collectively, as those pockets of space, which will eventually develop into matter-filled galaxies, clusters, super-clusters and filament walls. Using this model, we can find the energy needed for cosmic expansion using basic thermodynamic principles, and prove that cosmic expansion had as its origin, a finite initial energy density, pressure, volume, and temperature. Inflation in the traditional sense, with the inflaton field, may also not be required. We will argue that homogeneities and in-homogeneities in the WMAP temperature profile is attributable to quantum mechanical fluctuations about a fixed background temperature in the initial isothermal expansion phase. Fluctuations in temperature can cause certain regions of space to lose heat. Other regions will absorb that heat. The voids are those regions which absorb the heat forcing, i.e., fueling expansion of the latter and creating slightly cooler temperatures in the former, where matter will later congregate. Upon freeze-out,
2
this could produce the observed WMAP signature with its associated CBR fluctuation in magnitude. Finally, we estimate that the freeze-out temperature and the freeze-out time for WMAP in-homogeneities, occurred at roughly 3.02 * 1027 K and 2.54 * 10-35 s, respectively, after first initiation of volume expansion. This is in line with current estimates for the end of the inflationary epoch. The heat input in the inflationary phase is estimated to be Q = 1.81 * 1094 J, and the void volume increases by a factor of only 5.65. The bubble voids in the observable universe increase, collectively, in size from about .046 m3 to .262 m3 within this inflationary period.

**Comments:** 38 Pages. already published;Pilot, C, 2018, Is Quintessence an Indication of a Time-Varying Gravitational Constant?, https://arxiv.org/abs/1803.06431 , Journal of High Energy Physics, Gravitation and Cosmology (JHEPGC) JHEPGC Vol 5 No 1 (2019)

A model is presented where the quintessence parameter, w, is related to a time-varying gravitational constant. Assuming a present value of w = -.98, we predict a current variation of Ġ/G = - .06 H0, a value within current observational bounds. H0 is Hubble’s parameter, G is Newton’s constant and Ġ is the derivative of G with respect to time. Thus, G has a cosmic origin, is decreasing with respect to cosmological time, and is proportional to H0, as originally proposed by the Dirac-Jordan hypothesis, albeit at a much slower rate. Within our model, we can explain the cosmological constant fine-tuning problem, the discrepancy between the present very weak value of the cosmological constant, and the much greater vacuum energy found in earlier epochs (we assume a connection exists). To formalize and solidify our model, we give two distinct parametrizations of G with respect to “a”, the cosmic scale parameter. We treat G-1 as an order parameter, which vanishes at high energies; at low temperatures, it reaches a saturation value, a value we are close to today. Our first parametrization for G-1 is motivated by a charging capacitor; the second treats G-1(a) by analogy to a magnetic response, i.e., as a Langevin function. Both parametrizations, even though very distinct, give a remarkably similar tracking behavior for w(a), but not of the conventional form, w(a) = w0 + wa (1-a), which can be thought of as only holding over a limited range in “a”. Interestingly, both parametrizations indicate the onset of G formation at a temperature of approximately 7 *1021 degrees Kelvin, in contrast to the ΛCDM model where G is taken as a constant all the way back to the Planck temperature, 1.42 * 1032 degrees Kelvin. At the temperature of formation, we find that G has increased to roughly 4*1020 times its present value. For most of cosmic evolution, however, our variable G model gives results similar to the predictions of the ΛCDM model, except in the very early universe, as we shall demonstrate. In fact, in the limit where w approaches -1, Ġ/G vanishes, and we are left with the concordance model. Within our framework, the emergence of dark energy over matter at a scale of a ≈ .5 is that point where G-1 increases noticeably to its current value G0-1. This weakening of G to its current value G0 is speculated as the true cause for the observed unanticipated acceleration of the universe.

An isolated physical system of elastic collision between two identical
objects is chosen to verify the
conservation of momentum in two inertial reference frames. In the
first reference frame,
the center of mass (COM) is stationary. In the second reference frame, the center of mass
moves at a constant velocity. By applying
Lorentz transformation to the velocities of both objects, total momentum before and
during the collision in the second reference frame can be compared. The comparison
shows that conservation of momentum fails to hold
when both objects move together at the same velocity.

While general relativity provides an accurate description of spacetime and gravitational forces and effects, it does not provide a mechanism for gravity itself. By explaining the mechanism of gravitational force as a resistance of massive and high energy objects to the observed accelerating expansion of the universe, we simplify and provide a model that does not rely on unobserved particles or other hypothetical factors while staying in agreement with general relativity.

There is an open question in cosmology about the significance of the difference between the 2016 Planck collaboration value H0=66.93±0.62 km/s/Mpc and the 2016 Riess et al value H0=73.24±1.74 km/s/Mpc. This paper shows that both the Planck collaboration and Riess et al values are valid. Tracing the cosmological redshift z from SN1a several thousand megaparsecs in the past to those that exploded closer to today describes an increase in our perception of Hv as distance to us lessens. A best fit power function of vr=73.227*Dp^0.9907 for recessional velocity versus proper distance (where vr is recessional velocity and Dp is proper distance) is derived connecting these two values of H0 using 1836 SN1a in the NED database. Taking the derivative of this formula to get Hubble slope gives the power function Hv=dvr/dDp= 72.546*Dp^(-0.0093). When this formula is used to describe an extrapolation of the universe from near the Milky Way galaxy to the Cosmic Microwave Background (CMB), it describes a change of about 7 km/s/Mpc in the Hubble value for the observable universe increasing smoothly from 66.4 for our measures at the CMB to 73.4 km/s/Mpc locally as the universe expands. Most of the increase occurs in the last 1000 Mpc as was stated in Riess, Perlmutter, and subsequent SN1a studies. This is consistent with ΛCDM cosmology. After converting distance in megaparsecs to light-seconds, it is possible to show Hv is an acceleration that varies from 6.45 angstrom/s/lt-s when measuring the CMB to 7.13 angstrom/s/lt-s in the local universe.

We presented the difficulties of Maxwell’s electromagnetic theory and Einstein’s gravitational theory in detail, established a new unified theory of field including consistent electromagnetic theory and gravitational theory on the basis of new starting postulates, and applied these theoretical methods to quantum electrodynamics. We accepted a new geometrical space in which metric tensor and all main physical functions become implicit functions, called “KR space” consistent to our starting postulates, and normalization of implicit functions in order to give physical meanings to all physical functions of implicit forms defined in this space. As a result, we naturally unraveled problem of radiation reaction, a historical difficult problem of Maxwell-Lorentz electromagnetic theory, built new quantum electrodynamics without renormalization procedure followed by quantum gravitational theory and also predicted new theoretical results which could not find in traditional theories.

If you want to explain how the Universe works, it is necessary to know how the clusters of matter that originate the galaxies and the clusters of galaxies that originate the large-scale geometry of the Universe are formed. On the other hand, it is also necessary to know the mechanisms by which galaxies evolve and interact among them, and also, what the process for mater aggregation are. Finally, it is also necessary, therefore, an explanation of dark matter in terms of properties and not its composition, since it is a majority part of the matter of the Universe. A series of mechanisms and numerical models are established, which explain all this.

The intent of this work is to present a discussion of the Galilean Principle of Relativity and of its implications for what concerns the characteristics of light propagation and the nature of simultaneity. It is shown that by using a clock synchronization procedure that makes use of isotropically propagating signals of generic nature, the simultaneity of distinct events can be established in a unique way by different observers, also when such observers are in relative motion between themselves. Such absolute nature of simultaneity is preserved in the passage from a stationary to a moving reference frame also when a set of isochronous generalized coordinates is introduced. These transformations of coordinates can be considered as a generalization of the Lorentz transformations to the case of synchronization signals having characteristic speed different from the speed of light in vacuum. The specific invariance properties of these coordinate transformations with respect to the characteristic speed of propagation of the synchronization signals and of the corresponding constitutive laws of the underlying physical phenomenon are also presented, leading to a different interpretation of their physical meaning with respect to the commonly accepted interpretation of the Lorentz transformation as a space-time distortion. On the basis of these results, the emission hypothesis of W. Ritz, that assumes that light is always emitted with the same relative speed with respect to its source and that is therefore fully consistent with the Galilean Principle of Relativity, is then applied to justify the outcomes of the Michelson-Morley and Fizeau interferometric experiments by introducing, for the latter case, an additional hypothesis regarding the possible influence of turbulence on the refractive index of the fluid. Finally, a test case to verify the validity of either the Galilean or the Relativistic velocity composition rule is presented. The test is based on the aberration of the light coming from celestial objects and on the analysis of the results obtained by applying the two different formulas for the resultant velocity vector to process the data of the observed positions, as measured by a moving observer, in order to determine the actual un-aberrated location of the source.

String theory is a branch of theoretical physics that studies the dynamics of interaction not of point particles, but of one-dimensional extended objects, the so-called quantum strings. String theory combines the ideas of quantum mechanics and the theory of relativity, so it may be based on the future theory of quantum gravity.

The present scientific paradigm does not allow cosmological analysis because of the non-simultaneity of data. However, a cosmological analysis was realized through a new method (the concept of Light Coordinate System). This new method also indicates that the theory of special relativity and light kinematics can be revised and improved to become more functional and useful. In this article, the essence and details of important/supplement factors (especially considering: the types of relativity, sequential chain of reference systems, prioritizing the method of co-reference frame, and relational holism) are explained.

At least one observational study has claimed that Newton's gravitational constant seems to vary with the direction relative to the fixed stars, see [1]. We think this is unlikely, but such experiments should be repeated or at least investigated further. If it is the case that gravity is directionally dependent, then how could this be explained, and how could/should our gravity formulas be modified?
In this paper, we introduce an anisotropic big G that is dependent on the direction relative to the fixed stars, and therefore on a given location on Earth, dependent on the Earth's rotation. A series of experiments claim to have found the anisotropic one-way speed of light when getting around Einstein-Poincare synchronization, although they have not received a great deal of attention. We do not question that the one-way speed of light is isotropic when measured with Einstein-Poincare synchronized clocks. We hypothesize here that gravity moves with the speed of light and that the true one-way speed of gravity is anisotropic. Based on this, we get an anisotropic gravitational ``constant," which, if calibrated to one-way light experiments, is inside two standard deviations of error as given by CODATA.

In special relativity, we operate with length contraction and length transformation; these are not the same thing even though they are related. In addition, we have time dilation and time transformation. However, when it comes to mass, we have only relativistic mass and no mass transformation. We will suggest here, based on a better understanding of mass at the quantum level, that there must also be a Lorentz mass transformation. Recent research strongly indicates that mass is directly linked to the Compton wavelength of the particle in question and since we can operate with both length contraction and length transformation, this means we should have corresponding masses. Length contraction of the Compton wavelength corresponds to what is known today as relativistic mass, while length transformation means we also need mass transformation.
