On the radial geodesics of Kerr's manifold
Angelo Loinger, Tiziana Marsico
The so-called stationary-limit surface of Kerr's manifold represents an nsuperable barrier for the arriving material elements and light-rays.
Hilbertian Repulsive Effect and Dark Energy
Angelo Loinger, Tiziana Marsico
A repulsive gravitational effect of general relativity (without cosmological term), which was pointed out by Hilbert many years ago, could play a decisive role in the explanation o…
Highest-Energy Cosmic Rays and Hilbertian Repulsive Effect
Angelo Loinger, Tiziana Marsico
We point out that an important portion of the high energy of the cosmic rays from extragalactic sources can be attributed to a Hilbertian repulsive effect, which is a consequence o…
On repulsive gravitational actions
Angelo Loinger, Tiziana Marsico
In particular instances and in particular regions the Einsteinian gravity exerts a repulsive action -- and without any cosmological term. This fact could have an interest for the e…
On spherically symmetric structures in GR
Angelo Loinger, Tiziana Marsico
We reconsider some subtle points concerning the relativistic treatment of the gravitational fields generated by spherically symmetric structures.
Gravitational collapses to bodies of a finite volume
Tiziana Marsico, Angelo Loinger
We prove with an exact relativistic computation that the spherosymmetric gravitational collapses with a time-dependent pressure end in bodies with a small, but finite volume. Again…
