Anomalous Flyby in the Non-Prefered Reference Frame of the Rotating Earth
Walter Petry
Several spacecrafts show an anomalous flyby. In a previous paper a non-prefered reference frame is studied moving uniformly relative to the prefered one. In this article the Dopple…
Cosmology with Bounce by Flat Space-Time Theory of Gravitation and a New Interpretation
Walter Petry
General relativity predicts a singularity in the beginning of the universe being called big bang. Recent developments in loop quantum cosmology avoid the singularity and the big ba…
The Equations of Maxwell for a Medium in Prefered and Non-Prefered Reference Frames
Walter Petry
Let us consider a reference frame for which the pseudo-Euclidean geometry is valid (prefered frame). The equations of Maxwell in empty space have a simple form and are derived from…
Non-Stationary Star and the Trajectory of a Circulating Test Body
Walter Petry
A simple model of a spherically symmetric, pulsating star is calculated. The application to the Sun gives a 166-min radial pulsation. The theory of gravitation in flat space-time i…
Non-Prefered Reference Frames and Anomalous Earth Flybys
Walter Petry
Let us consider a reference frame Sigma prime in which the pseudo-Euclidean geometry holds. Einstein assumed that the principle of special relativity is valid, i.e. the reference f…
Unified Description of Dark Energy and Dark Matter
Walter Petry
Dark energy in the universe is assumed to be vacuum energy. The energy-momentum of vacuum is described by a scale-dependent cosmological constant. The equations of motion imply for…
