Bekenstein Bound of Information Number N and its Relation to Cosmological Parameters in a Universe with and without Cosmological Constant
Ioannis Haranas, Ioannis Gkigkitzis
Bekenstein has obtained is an upper limit on the entropy S, and from that, an information number bound N is deduced. In other words, this is the information contained within a give…
Kretschmann Invariant and Relations Between Spacetime Singularities, Entropy and Information
Ioannis Gkigkitzis, Ioannis Haranas, Omiros Ragos
Using a yukawa type of metric we derive the kretschmann scalar for a general static black hole of a certain mass. The scalar gives the curvature of the space time as a function of…
The Lens-Thirring effect in the anomalistic period of celestial bodies
Ioannis Haranas, Omiros Ragos, Ioannis Gkigkitzis
In the weak field and slow motion approximation, the general relativistic field equations are linearized, resembling those of the electromagnetic theory. In a way analogous to that…
Effects in the Anomalistic Period of Celestial Bodies due to a Logarithmic Correction to the Newtonian Gravitational Potential
Omiros Ragos, Ioannis Haranas, Ioannis Gkigkitzis
We study the motion of a secondary celestial body under the influence of the logarithmic corrected gravitational force of a primary one. This kind of correction was introduced by F…
