It was thought that the behaviour of black holes can be described by quantum laws. In this model, using Schrödinger equation and the ordinary gravitational field equation for spherical bodies, a new quantum gravity equation was proposed to describe the behaviour of the black holes. Assuming that the universe undergo a phase transition to become a black hole or if the solar system is trapped by a black hole, the time evolution will certainly be different from that of our ordinary solar system. This work proves that the distance traversed by the moon in one day inside the black hole is equal to that traversed by the moon in 1000 year.</span></p> 2025-10-31T00:00:00+00:00 Copyright (c) 2025 Mohamed Farah Idris , Shawgy Hussain AbdAlla, Mubarak Dirar AbdAlla https://www.rajpub.com/index.php/jap/article/view/9812 Sayed`s Theory on Quantum Entanglement and Teleportation: Innovative Controlling Parameters and Equations of Occurrence; E =β mc3 2025-10-12T13:07:03+00:00 Sayed A. El-Mongy sayedelmongy@hotmail.com <p><strong>Abstract</strong></p> <p>Allah, the Creator, is entangled with everything in the universe. The Quantum Entanglement is neither spooky action at a distance nor science fiction. This theory introduces the parameters controlling the quantum entanglement and teleportation occurrence. A Sayed Quantum entanglement energy equation <strong>(<em>SQEEE</em>); E =β mc<sup>3</sup></strong>, with variable speed, was derived to describe the quantum entanglement phenomena. The entanglement speed was found to be variable with distance and in the range from ~1x10<sup>12</sup> to 1.318 x 10<sup>22</sup>m/s. The light speed violation is a must The Sayed quantum entanglement wavelength (<em>SQEW) was calculated and found to be 2.487 x 10<sup>-35</sup> m</em> in the Planck scale. The quantum teleportation mechanism of an object from the macroscopic into the microscopic fields might take place through Sayed`s quantum teleportation tunneling (SQTT). Sayed quantum teleportation wavelength (SQTW) was derived and found to be 5.135x10<sup>-35</sup>m for Planck scale. A hypothetical case for object quantum teleportation acceleration (SQTA) was also calculated and found to be 4.738x10<sup>20</sup> m/s<sup>2</sup>. It can be imagined that the universe (visible and invisible) is connected and entangled in the quantum scale by encrypted vibrational waves of specific wavelengths as the code of communication between all the universe web components. Sayed`s Quantum Entanglement &amp; Teleportation Diagram (SQETD) was proposed.</p> 2025-10-31T00:00:00+00:00 Copyright (c) 2025 Sayed A.

The electric charge began in the early universe during the first few minutes. The first moments after the Big Bang are called the quark-gluon plasma phase. During this phase, there are two distinct periods. The first occurs immediately after the universe's start. The temperatures are so high during the first few minutes that quarks and gluons form strings. The top quark and antibottom quark are strings during this time in the early universe. As they collide, they start to spin, oscillate, and rotate, eventually merging into a single quark. This heavy quark, called the CD-quark, was responsible for developing electric charges in the early universe. Changes in the mass of the CD-quark are the true origin of electric charges. Electric charge is not dependent on mass, but rather on the mass change that occurred during the early universe. The CD-quark spins faster than the speed of light and vibrates in different modes, leading to the creation of electrons, protons, and neutrons. If it rotates clockwise, it generates a negative charge and shifts its vibration mode to produce an electron. An electron is not a fundamental particle. If it spins counterclockwise, it creates a positive charge and shifts into a proton. Some CD-quarks do not spin, resulting in a third vibration mode that creates a neutron. The CD-quark is a heavy quark; however, it is unique because the quark and antiquark are composed of different quarks. This property is crucial for the creation of electric charges and the formation of fundamental particles in the early universe. The CD-quark is the only source of electrons, protons, and neutrons during the first few minutes after the universe begins. After that, CD-quarks cease to exist. Charged particles have finite lifetimes; they are not stable like other particles. </span></p> 2025-10-05T00:00:00+00:00 Copyright (c) 2025 David McGraw Jr., PhD https://www.rajpub.com/index.php/jap/article/view/9785 Study on momentum density in semiconductor compounds AlBi, InBi, and GaBi by positron annihilation 2025-08-06T07:42:55+00:00 O.

It focuses on unconventional "vacuum-induced pulling forces," a phenomenon largely overlooked by traditional thermodynamics, where cooling a thermal working fluid (TWF) generates a vacuum and produces mechanical work without direct thermal energy input.

This strategy facilitates the use of identical PUs, minimizing the number of units required while maximizing life-cycle benefits. A constant ΔT is critical for ensuring consistent useful work output under a constant heat input. The primary objective is to determine the optimal number of cascaded PUs that maximizes the system's self-sufficiency index and overall performance.</span></p> <p><span style="font-weight: 400;">Design results indicate that the optimal SSPP configuration, achieving a peak self-sufficiency index, utilizes 8 to 9 cascaded PUs for a ΔT between 40–50 K.

Nonetheless, experimental evidence suggests that useful mechanical work can be generated not only by adding heat but also by extracting it. This process creates a vacuum that produces traction forces, which in turn can yield mechanical work—potentially paving the way for self-sufficient power engines. This article explores plausible technological pathways based on traction or pulling forces, which have been largely overlooked in conventional thermodynamic systems. These forces can be induced by cooling a thermal working fluid, generating vacuum without direct energy input. Achieving a truly self-sufficient heat engine would require rethinking or even challenging foundational principles of thermodynamics, including the conservation of energy, the first law of thermodynamics, Carnot’s theorem, and the concept of exergy. In fact, this proposal undergoes a feasible disruptive path toward Self-Sufficient Power Engines (SSPE). The best result among four cases studied consists of a self-sustaining power plant (SSPE) composed of a cascade of nine Power Units (PUs) that provide a self-sufficiency index of 250 with respect to a reference of 100 and a net electrical power of 597 (kJ/kg) per cycle.</p> 2025-09-05T00:00:00+00:00 Copyright (c) 2025 Ramon Ferreiro Garcia https://www.rajpub.com/index.php/jap/article/view/9777 Universe End by Phase Transition Due to Vacuum Energy Change According to the Black Hole Model 2025-07-24T11:44:43+00:00 Mohamed Farah Idris mtaifour1979@gmail.com Shawgy Hussain AbdAlla mtaifour1979@gmail.com Mubarak Dirar AbdAlla mtaifour1979@gmail.com <p><span style="font-weight: 400;">In this work, a new scenario was propose 8d for the end of the present universe through a phase transition which is based on the expression of the mass in the potential dependent special relativity.

These engines, which operated using vacuum-induced contraction rather than steam expansion, seemingly violated the first law of thermodynamics—conservation of energy—before it was formally articulated by Rudolf Clausius in the mid-19th century. Papin's innovative approach utilized thermal contraction and atmospheric pressure to perform mechanical work, a method later refined by Newcomen. The engines achieved work through vacuum generation by condensing steam with cold water, a process that contradicted the conventional understanding of energy conservation as later defined by Clausius and Carnot. The paper analyzes the operational principles of Papin’s and Newcomen’s ASEs, highlighting how their contraction-based work led to an increase in internal energy while performing useful mechanical work, a phenomenon inconsistent with the first law of thermodynamics. The study also examines the transition from contraction-based engines to expansion-based systems, such as the Rankine cycle, and discusses the implications of these early engines on the development of thermodynamic theory. Through case studies and experimental evidence, the paper argues that the first law, as originally stated, fails to account for contraction-based work, suggesting a need for its revision to include such phenomena. The findings underscore the historical significance of Papin’s and Newcomen’s contributions to engineering and thermodynamics, while also raising questions about the completeness of classical thermodynamic principles.</span></p> 2025-02-23T00:00:00+00:00 Copyright (c) 2025 Ramon Ferreiro Garcia https://www.rajpub.com/index.php/jap/article/view/9700 The Origin Of Electric Charge And Its Relation To Closed And Open Strings In The Early Universe 2025-01-20T23:59:41+00:00 David McGraw Jr. dmcgraw1@mcneese.edu <p><span style="font-weight: 400;">The C-Neutralino, a particle of immense significance, is the primary particle that drives the beginning of our universe. The C-Neutralino decays into other particles, including protons and electrons. The C-Neutralino existed before the beginning of time. They were the catalyst for the start of our universe.

We understand this as the Big Bang that happened at the beginning of our universe. The electric charge starts in the early universe during the first few minutes. The first moments after the Big Bang are called the quark-gluon plasma phase. In this phase, there are two different periods. The first period occurs right after the beginnings of the universe. The temperatures are so hot during the first few minutes that the quarks and gluons are strings. The top quark and the antibottom quark are strings during this time in the early universe. As they collide, they start to spin, oscillate, and rotate, becoming one quark. This heavy quark called the cd-quark, was responsible for developing electric charges in the early universe. This change in mass of the cd-quark is the true origin of electric charges. Electric charge is not mass dependent on mass amount but on mass change in the early universe. Charged particles have finite lifetimes. They are not stable like other particles. </span></p> 2025-02-23T00:00:00+00:00 Copyright (c) 2025 David McGraw Jr.
