Though it has been proved earlier, on historical basis that the ancient Map of Loka (Universe) prepared by Risis is a statistical chart, scholars were still skeptical about its hypothesis. This has been blocking worthwhile progress in the field. As such it has become necessary to re-examine and test the map against the various criteria and scope of cartography. It is found that it cannot be a Geographical map. In the light of several new evidences, it has been conclusively proved that it is an enriched statistical chart only. It has been then shown as to how this theory removes the present contradictions and mismatches of the map with the scientific findings. Interpretations of its several contents as per the new theory reveal wonderful specific data about hitherto unknown or speculative objects of living and non-living realms, like existence of aliens, underground world and invisible worlds. It also reveals not only its characteristics, but also specifies properties of some special types of body materials and existence of other types of living-beings. Attempt has been made to understand and clarify these features by answering several queries about them.

In this paper, we consider the existence and nonexistence of non-trivial solutions to elliptic equations with cylindrical potentials, concave term and subcritical exponent. First, we shall obtain a local minimizer by using the Ekeland’s variational principle. Secondly, we deduce a Pohozaev-type identity and obtain a nonexistence result.

The arguments employed by Einstein that led him to the conclusion that “we cannot attach absolute meaning to the concept of simultaneity” are subjected to critical analysis in light of experiments that have subsequently been carried out with atomic clocks. The physical significance of time dilation is a key element in this discussion. It is pointed out that the fact that two clocks at rest in a laboratory disagree on the elapsed time for a given event is normally interpreted to mean that they are not properly synchronized or that they run at different rates, not that the event in question did not occur simultaneously for them. An experiment using GPS technology is outlined to test whether events really do not occur simultaneously for all observers or if instead that their timing results only differ because the clocks employed by them run at systematically different rates. An example of two light pulses moving in opposite directions shows that one can come to a different conclusion about simultaneity depending on whether the Lorentz transformation (LT) of space-time coordinates or the associated relativistic velocity transformation (RVT) is employed as justification. Finally, it is shown that it is possible to satisfy Einstein’s two postulates of relativity while still maintaining the principle of absolute simultaneity of events by introducing an alternative (Global Positioning System) Lorentz space-time transformation (GPS-LT) that is also perfectly consistent with the RVT.

The photon mass was initially described in the Compton equation where the Compton wavelength of a particle is equivalent to the wavelength of a photon whose energy is the same as the “rest”-mass energy of the “particle”. The m is the photon mass, C is the speed of light and h is Planck's constant: λ=h/mc. However, most scientists deny photon’s mass status. In this paper, the author will assure you that photons have mass, which also happens to serve the base for all gravitational power/positional energy that exists today after a big bang. Furthermore, the photon as an energy carrier has its actual physical existence which can be inferred by nuclear force: at distances less than 0.7 fm (fm, or 1.0 × 10-¹ÃƒÂ¢Ã‚Âµmetres), the nuclear force becomes repulsive where the phenomenon of such repulsive component is responsible for the physical size of the nuclei. All nuclear power (strong or weak) existing after a big bang derives from a big bang’s photon/radiation. In this paper, the author also assures you that neutrinos are dark matter that floats in the space chilling with electrons (- and ⁺) where the gamma ray burst is just a cosmic-sized volume of our well-studied experiment in our lab: e- + e⁺ → γ + γ! The primary objective of this study is to uncover the unified origin for both mass and energy in the universe along with their evolutionary path in the discipline of Newtonian physics.

This project will be aimed at modelling the supersonic flow inside Scramjet engine using the Computational Fluid Dynamics CFD ANSYS Fluent. Scramjet Engine starts at a hypersonic free stream Mach no. 5.00. When pressures and temperatures become so high in supersonic flight that it is no longer efficient to slow the oncoming flow to subsonic speeds for combustion, a scramjet (supersonic combustion ramjet) is used in place of a ramjet. Supersonic flow from a nozzle that represents the exhaust nozzle of a supersonic combustion ramjet SCRAMJET is modelled. Jet from the nozzle is issued into a domain which is bounded on one side by an after body wall which is parallel to the center line of the nozzle. Shocks propagating from the nozzle exit reflect from the after body. Outflow from scramjet engines can have a significant impact on both the heat transfer and the pressure distribution on the section of the aircraft that lies downstream. Most importantly, reflecting shock waves lead to large peaks in the distributions. Two geometrical configurations for the after body are tested. Experimental values are used because this span wise region is closest to the centre of the experimental model where the three-dimensional effects are minimal. Measured values of the distribution of wall pressure and heat transfer rate along the after body are used to validate the CFD simulation.

It is postulated that forces beyond event horizon are enormous. With such intensity of interplay of forces, spacetime distortion is a possible phenomenon. This paper attempts to interpret disintegration of space-time beyond event horizon and predicts its consequences.

This study explains the most important moons in solar system and their distribution in the planets. The research will also show the relationship between the mass of the planets, number of natural satellite of the planets and the distance of planets from the Sun. Furthermore, the study indicates the origin of moons and most interesting properties of the giant moons in Jupiter, Saturn, Uranus and Neptune System.

Astronomical jets are observed from the centres of many Galaxies including our own Milkyway. The formation of such jet is explained using SITA simulations of dynamic universe model. For this purpose the path traced by a test neutron is calculated and depicted using a set up of one densemass of the mass equivalent to mass of Galaxy center, 90 stars with similar masses of stars near Galaxy center, mass equivalents of 23 Globular Cluster groups, 16 Milkyway parts, Andromeda and Triangulum Galaxies at appropriate distances. Five different kinds of theoretical simulations gave positive results. The path travelled by this test neutron was found to be an astronomical jet emerging from Galaxy center.
