Scientific Study from the year 2003 in the subject Physics - Theoretical Physics, University of Barcelona, language: English, abstract: By assigning the elementary Planck units to the units of Newton¿s Gravitational Constant (G), it resulted that G is actually a function of vacuum (zero point) energy (ZPE) and that it can be therefore manipulated. This paper cites and discusses some possible kinds of Gravity manipulation. ZPE appears to reduce gravity as it is inversely proportional to the gravitational force. From Coulomb¿s Constant, the ¿Planck charge¿ (qP) and the corresponding quantum vacuum (QV) lepton/photon ratio are calculated, the latter by dividing qP by the Planck mass. The QV-lepton/photon ratio is very different to the analogous baryon/photon ratio that is predicted by Standard Model, demonstrating that the QV and space-time are two different entities (e.g., that they have a different number of dimensions). A dimensional model for the QV that evolves from, and is supported by, the lepton/photon ratio is presented herein, together with emerging technologies. By expressing natural constants in terms of Planck units, we found that the Universal Gravitation Constant is the inverse of vacuum density matter-equivalent and the square of Planck time, being the former equal to Planck mass divided by Planck volume. The corresponding new equation of gravitation presented here reveals that gravitation can be manipulated via vacuum energy. Additionally, from Coulomb¿s constant, we can derive the ¿Planck charge¿ and the corresponding density of virtual vacuum particle pairs. A discussion of the ramifications of these findings is also presented.
