Does gravitational collapse lead to singularities?
Ernst Fischer
According to conventional modelling by general relativity the collapse of radially symmetric gravitating objects may end in a singular state. But by inclusion of potential energy i…
The properties of dark matter
Ernst Fischer
Observations of density profiles of galaxies and clusters constrain the properties of dark matter. Formation of stable halos by collisional fluids with very low mass particles appe…
Energy Loss by Gravitational Viscosity
Ernst Fischer
Due to Lorentz invariance of General Relativity gravitational interaction is limited to the speed of light. Thus for particles, moving within a matter field, retardation leads to l…
An Equilibrium Balance of the Universe
Ernst Fischer
An alternative cosmological model is presented, which avoids the requirement of dark energy and dark matter. Based on the proposition that energy conservation should be valid not o…
Red Shift from Gravitational Back Reaction
Ernst Fischer
Deviations from geodesic motion caused by gravitational radiation have been discussed in the last decades to describe the motion of particles or photons in strong fields around col…
Thermal structure of gas in relaxed clusters of galaxies
E. Fischer
Gas clouds under the influence of gravitation in thermodynamic equilibrium cannot be isothermal due to the Dufour effect, the energy flux induced by density gradients. In galaxy cl…
