On the Indication from Pioneer 10/11 Data of an Anomalous Acceleration

Hubble's law, which states a linear increase in velocities with distances, can physically be understood in terms of an acceleration cH. This work proposes a connection between this "universal" acceleration seen in the solar system and the anomalous acceleration acting on the Pioneer 10/11 spacecraft, in which the Hubble constant inferred from Pioneer 10/11 data is ~ 87 km/s/Mpc. Its physical implication is discussed in relation with Mach's principle.

Lagrangian Approach to Quantum Mechanics

The Lagrangian approach of Dirac is presented in a complete form. This suggests to identify the Schrödinger equation as the Euler-Lagrange equation rather than the Hamiltonian operator equation.

Physics of Aberration rather than Special Relativity

A phenomenological explanation is presented for the physics of aberration, which is in contrast with special relativity physics. The effect of relativity is identified with an effect due to the velocity of observation being affected by the velocity of a moving particle. In contrast with the currently accepted view, it is demonstrated that the classical concepts of time and simultaneity are natural for describing relativistic phenomena.

Optical Approach to Gravitational Redshift

An optical approach begins by interpreting the gravitational redshift resulting to a change in the relative velocity of light due to the medium of propagation in the gravitational field. The discussion continues by pointing out an agreement in structure between the equation for rays in geometrical optics and the geodesic equation of general relativity. From their comparison we learn that the path of rays should be given by the relation $ds^2=n^2(r)dr^2+r^2dθ^2$, not by $ds^2=dr^2+r^2dθ^2$, in a medium with spherical symmetry of refractive index $n(r)$. The development of an optical analogy suggests introducing $n^2(r)$ in place of $g_{rr}$ as an optical version of the Schwarzschild metric. In form and content, $n^2(r)$ is different from $g_{rr}$. The optical point of view replaces the general-relativity explanations in terms of time and gravitation.

General-Relativistic Equations of Motion in terms of Energy and Angular Momentum

An attempt is made to describe the general-relativistic equations of motion for the Schwarzschild geometry in terms of the classical concepts of energy and angular momentum. Using the customary terms the geodesic equations can be viewed in a way that is very helpful in providing the physical meaning of the mathematical development.
