Extracting Gravitational Energy From The Homogeneous Isotropic Universe
  The kinetic energy of a local system of objects placed in a curved spacetime is gained by the subsequent acceleration of the object following the more contracted region of spacetime. Normally this happens near massive gravitating stars. However, the gravitational dipole moment has been shown to be capable of self creating asymmetrically distorted spacetime in its vicinity, therby, capable of being accelerated indefinitely following the successive self created loophole of the spacetime. Localization of this kinetic energy may be possible by designing a system that uses the artificially created gavitational dipole moments to rotate the main axis. A mechanical constraint is derived for the extraction of unlimited gravitational energy from such system.
