Geodesic motion and confinement in Goedel's universe

Creators

Description

A complete study of geodesic motion in Goedel's universe, using the method of the Effective Potential is presented. It then emerges a clear physical picture of free motion and its stability in this universe. Geodesics of a large class have finite intervals in which the particle moves back in time (dt/ds<0) without violation of causality. Goedel's geometry produces the important property of confinement for a large class of geodesics. This property to discuss the construction of a gravitational container is used. This structure is highly stable, since there is no singularity in its interior, and independent of the energy of the particles contained in it. (Author)

Abstract (Portuguese)

Apresenta-se um estudo completo do movimento Geodesico no universo de Goedel, usando o metodo do potencial efetivo. Tem-se entao, um quadro fisico claro do movimento livre e sua estabilidade nesse universo. A Geodesica de uma classe grande tem intervalos finitos no qual as particulas se movem de volta no tempo (dt/ds<0) sem violacao de casualidade. A geometria de Goedel fornece a propriedade importante de confinamento para uma classe grande de geodesicas. Usa-se essa propriedade para discutir a construcao de um pacote de gravidade. Essa estrutura e altamente estavel, desde que nao haja singularidade no seu interior, e independa da energia das particulas contidas dentro dele. (M.A.F.)
