We derive the light deflection caused by the screw dislocation in space-time. The derivation is based on the idea that space-time is a medium which can be deformed by gravity and that the deformation of space-time is equivalent to the existence of gravity.
Strictly respecting the Einstein equations and supposing space-time is a medium, we derive the deformation of this medium by gravity. We derive the deformation in case of infinite plane, Robertson-Walker manifold, Schwarzschild manifold and gravitational waves. Some singularities are removed or changed. We call this procedure renormalization of gravity. We show that some results following from the classical gravity must be modified.
The power spectrum of the synchrotron radiation generated by the motion of a two-body charged system in an accelerator is derived in the framework of the Schwinger source theory. The final formula can be used to verify the Lorentz length contraction of the two-body system moving in the synchrotron.
After the historical background concerning the pressure of light, we derive the quantum field theory force of the laser radiation acting on electron. Numerically, we determine the velocity of an electron accelerated by laser beam, after acceleration time $Δt = 1 {\rm s}$.
The power spectrum formula of the synchrotron radiation generated by the electron and positron moving at the opposite angular velocities in homogenous magnetic field is derived in the Schwinger version of quantum field theory. The asymptotical form of this formula is found. It is surprising that the spectrum depends periodically on radiation frequency omega which means that the system composed from electron, positron and magnetic field forms the two-body electromagnetic pulsar.
The equations of massive electrodynamics are derived and the power spectrum formula for the Cherenkov radiation of massive photons is found. The Cherenkov power spectrum is determined also for the two-charge system. It is argued that the massive Cherenkov effect can be observed in superconductive media, ionosphere plasma, waveguides and in particle laboratories.
The string model of gravitational force is proposed where the string forms the mediation of the gravitational interaction between two gravitating bodies. It reproduces the Newtonian results in the first-order approximation and it predicts in the higher-oder approximations the existence of oscillations of the gravitational field between two massive bodies. It can be easily generalized to the two-body interaction in particle physics.
