General Relativity Theory also leads to the beginning of the universe from a singularity.
His formulas for [phi], e, a, and h are derived from general relativity theory by using the slow-speed weak-field approximation.
The time-retarded fields were derived from general relativity theory, but there is no need for further reference to the concepts and techniques of general relativity theory.
In 1916 Albert Einstein published his
general relativity theory, which attributes gravitational forces to changes in the curvature of space from point to point.
In this regard, we would like to emphasize that our preceding paper [3] was based on initial "conjecture" that in order to explain Pioneer anomaly, it would be necessary to generalize pseudo-Riemann metric of
General Relativity theory into broader context, which may include Yefremov's Quaternion Relativity for instance.
Despite the nature of such anomalous blueshift remains unknown, some people began to argue that a post-einsteinian gravitation theory may be in sight, which may be considered as further generalisation of pseudo-Riemannian metric of
general relativity theory.
