Stabilization of Thin Shells By Gravitational Effects From Electric Fields Academic Article uri icon


  • We study the properties of a system consisting of an uncharged spherically symmetric two dimensional extended object which encloses a stationary point charge placed in the shell's center. We show that there can be a static and stable configuration for the shell in this specific system, using only the gravitational field of the charged source as a stabilizing mechanism. In particular, two types of shells are studied: the first is a dust shell and the second is a string gas shell. The dynamical possibilities are also analyzed, including the possibility of child universe creation.
