New Aspects of Photon Propagation in Expanding Universes
H. -J. Fahr, M. Heyl
According to present cosmological views the energy density of CMB (Cosmic Microwave Background) photons, freely propagating through the expanding cosmos, varies proportional to 1/S…
The influence of modified gravitational fields on motions of Keplerian objects at the far-edge of the Solar System
Michael Sokaliwska, Hans-Joerg Fahr, Pavel Kroupa
We investigated the impact of three different modifications of Newtonian gravity on motions of Keplerian objects within the Solar System. These objects are located at distances of…
Does PIONEER measure local spacetime expansion?
Hans-Joerg Fahr, Mark Siewert
There is a longstanding mystery connected with the radiotracking of distant interplanetary spaceprobes like ULYSSES, Galileo and especially the two NASA probes PIONEER 10 and 11. C…
Concerning the instantaneous mass and the extent of an expanding universe
H. J. Fahr, Michael Heyl
In this article we want to answer the cosmologically relevant question what, with some good semantic and physical reason, could be called the mass of an infinitely extended, homoge…
About universes with scale-related total masses and their abolition of presently outstanding cosmological problems
H. J. Fahr, M. Heyl
Cosmological consequences of a strictly valid total energy conservation for the whole universe are investigated in this paper. Interestingly enough as one consequence of ergodicall…
2D stationary resistive MHD flows: borderline to magnetic reconnection solutions
Dieter H. Nickeler, Hans-Joerg Fahr
We present the basic equations for stationary, incompressible resistive MHD flows in two dimensions. This leads to a system of differential equations for two flux functions, one el…
