A Model for the Source of Repulsive Gravity |
|
Abstract |
We constructed the exact solution of the Einstein-Maxwell equations with the spherically symmetric Nambu-Goto charged membrane as a source. We stress that the physically acceptable range of parameters for which the static and stable state of the membrane producing the Reissner-Nordstrom (RN) repulsive gravity effect exists. The point is that membrane are able to cut out the central naked singularity region and at the same time to join in appropriate way the RN repulsive region. Then we have a model of an everywhere regular material source exhibiting a repulsive gravitational force in the vicinity of its surface: this construction gives a more sensible physical status to the RN solution for the naked singularity case. |
