Abstract

Using an Extended Scharzschild-Anti de Sitter (ESAdS) metric here introduced, where the noncompact extra dimension is time-like, we study the gravitational confinement of matter and photons from a 5D vacuum. The important result here obtained is that the photon trajectories (in general, massless particles), are periodic. They are confined to a radius r ⩽ 2 mG/c2 by the gravitational field. Massive test particles are also gravitationally confined, but their trajectories are not periodic.
