Gravitational and Anti-gravitational Applications
... It is now possible to partially deflect gravitation away from an object so that the gravitational attraction on the object is reduced. That effect makes it possible to extract energy from the gravitational field, which makes the generation of gravito-electric power technologically feasible. Such pla ...

For a point mass or a point charge we can draw so-called field lines to represent which way the force would point if we introduced a "test object" into the picture. O ...

On the Bel radiative gravitational fields Joan Josep Ferrando aez
... gravitational field radiative at a point of the space-time could be non radiative at another point. In this work we give several definitions and results that are also local because they are based on algebraic considerations. Here we revisit Bel’s ideas in depth. The analogy with electromagnetism hel ...
