The Exact Solution of The Pioneer Anomaly According to The General Theory of Relativity and The Hubble's Law

Authors: Azzam AlMosallami
Comments: 14 pages

Radio metric data from Pioneer 10/11 indicate an apparent anomalous, constant, acceleration acting on the spacecraft with a magnitude ~ , directed towards the Sun[1,2]. Turyshev [7] examined the constancy and direction of the Pioneer anomaly, and concluded that the data a temporally decaying anomalous acceleration with an over 10% improvement in the residuals compared to a constant acceleration model. Anderson, who is retired from NASA's Jet Propulsion Laboratory (JPL), is that study's first author. He finds, so "it's either new physics or old physics we haven't discovered yet." New physics could be a variation on Newton's laws, whereas an example of as-yet-to-be-discovered old physics would be a cloud of dark matter trapped around the sun[12]. In this paper I introduce the exact solution for the Pioneer anomaly depending on the general theory of relativity and the Hubble's law. According to my solution, there are two terms of decelerations that controls the Pioneer anomaly. The first is produced by moving the Pioneer spacecraft through the gravitational field of the Sun, which causes the velocity of the spacecraft to be decreased according to the Schwarzschild Geometry of freely infalling particle. This deceleration is responsible for varying behaviour of the Pioneer anomaly in Turyshev [7]. The second term is produced by the Hubble's law which is constant and equals to the Hubble's constant multiplied by the speed of light in vacuum.

A Note on the Mass-Energy Relation

Authors: José Francisco García Juliá
Comments: 1 Page.

The famous equation that relates the mass with the energy can be deduced without using the special relativity of Einstein; however, the relation obtained is slightly different.

On the Neutrino Opera in the CNGS Beam

Authors: Armando V.D.B. Assis
Comments: 6 pages, Published in the Journal Progress in Physics

In this brief paper, we solve the relativistic kinematics related to the intersection between a relativistic beam of particles (neutrinos, e.g.) and consecutive detectors. The gravitational effects are neglected, but the effect of the Earth rotation is taken into consideration under a simple approach in which we consider two instantaneous inertial reference frames in relation to the fixed stars: an instantaneous inertial frame of reference having got the instantaneous velocity of rotation (about the Earth axis of rotation) of the Cern at one side, the lab system of reference in which the beam propagates, and another instantaneous inertial system of reference having got the instantaneous velocity of rotation of the detectors at Gran Sasso at the other side, this latter being the system of reference of the detectors. Einstein's relativity theory provides a velocity of intersection between the beam and the detectors greater than the velocity of light in the empty space as derived in this paper, in virtue of the Earth rotation. We provide a simple calculation for the discrepancy between a correct measure for the experiment and a measure arising due to the effect derived in this paper.

Particularization of the Sequence of Spacetime/intrinsic Spacetime Geometries and Associated Sequence of Theories in a Metric Force Field to the Gravitational Field.

Authors: Akindele (Adekugbe) Joseph
Comments: 27 pages, Submitted to Progress in Physics. Author's name recently changed from Joseph Akindele O Adekugbe to Akindele O Adekugbe Joseph.

The two stages of evolution of spacetime/intrinsic spacetime and the associated spacetime /intrinsic spacetime geometries in a long range metric force field, isolated in previous papers, are particularized to the gravitational field. The theory of relativity on flat four-dimensional spacetime (E3, ct) and the intrinsic theory relativity on the underlying flat two-dimensional intrinsic spacetime (φρ, φcφt), due to the presence of a metric force field, as well as the absolute intrinsic metric theory (of the metric force field) on curved 'two-dimensional' absolute intrinsic spacetime (φρ^, φc^φt^), which evolve at the second (and final) stage of evolution of spacetime/intrinsic spacetime in a long range metric force field, developed in the previous papers, become the theory of gravitational relativity (TGR) on the flat four-dimensional relativistic spacetime, the intrinsic theory of gravitational relativity (φTGR) on the underlying flat two-dimensional relativistic intrinsic spacetime and the metric theory of absolute intrinsic gravity (φMAG) on the curved 'two-dimensional' absolute intrinsic spacetime in a gravitational field. The basic aspects of these co-existing theories in every gravitational field are developed.

The New Gravitational Theory and The Expansion Theory of The Universe

Authors: Chun-Xuan Jiang
Comments: 6 pages. In Chinese

Using the tachyonic theory we find the new gravitational formula (16) and establish the expansion theory of the Universe see Fig. 2, (22)-(25). We show that gravitons can be converted into the rest mass, see Fig. 2, m-bar → m, (24) and (27). We point out that Newtonian gravitational theory is approximate and the general theory of relativity is wrong.

Relativity and Quantum Electrodynamics in the Theory of Reference Frames: the Origin of Physical Time

Authors: Daniele Sasso
Comments: 8 pages.

In this paper the main aspects of the Theory of Reference Frames are presented: in particular we consider the relativistic relation between time and mass, the electrodynamics of a moving charged particle, the quantum electrodynamic behavior of accelerated electron and a new explanation of the Compton effect.

Momentum and Energy in the Schwarzschild Metric

Authors: Douglas L. Weller
Comments: 30 pages

Albert Einstein validated his field equations by demonstrating that they complied with what he called the laws of momentum and energy. The most well-known solution to Einstein's field equations is the Schwarzschild metric describing the gravitational field of a mass point. Here is examined how what Einstein called the laws of momentum and energy are manifest in the Schwarzschild metric and how these laws limit the geometry of space-time that is defined by the Schwarzschild metric.

A Fundamental Principle of Relativity

Authors: Douglas L. Weller
Comments: 32 pages

The laws of physics hold equally in reference frames that are in motion with respect to each other. This premise of Albert Einstein's theory of relativity is a fairly easy concept to understand in the abstract, however the mathematics-particularly the tensor calculus used by Einstein to describe general relativity-used to flesh out this premise can be very complex, making the subject matter difficult for the non-specialist to intuitively grasp. Here is set out a fundamental principle of relativity that can be used as a tool to understand and explain special and general relativity. The fundamental principle of relativity is used to independently derive the Lorentz factor, the Minkowski metric and the Schwarzschild metric. The fundamental principle is also used to derive metric tensors for systems with multiple point masses and to explain Newtonian kinetic energy, gravitational potential energy and mass-energy equivalence in the context of special and general relativity.

A Simple Numeric Example of a Contradiction in Special Relativity

Authors: Andrew Banks
Comments: 4 pages

Assume the standard configuration under Special Relativity (SR) and a light pulse is emitted when the origins of two coordinate systems are common. Further assume v = .6c and that the spherical light wave (SLW) has attained the unprimed coordinated (2ls,10ls,0) where ls is the distance light travels in 1 second. Then t1 = √104s and using LT, ( x'1 1.25(2-.6√104) ,10 ,0) x1 = - ls . Since x1 > and x'1 < , both frames agree along the line y = 10 the SLW is in between the two origins. According to nature, the SLW will propagate further. So, assume that condition. Both frames conclude, along the line y =10 , any further propagation of the SLW must place the SLW further from its own origin assuming the light postulate in its frame. A valid question to propose is, by considering coordinates only with y =10 and z = 0 , where will the SLW move to after further propagation? If both frames agree the SLW must move further from the respective origin, and the SLW is in between the two origins, then the SLW must move two different directions along the line y = 10 to satisfy the SR conditions of each frame. Based on this fact, it will be proven in the context of either frame, after further propagation of the SLW, Lorentz transformations (LT) will contradict the light postulate in the target frame.
