La Física de los Viajes en el Tiempo a través de un Agujero de Gusano

Abstract

This paper introduces us into the physics of time travel employing wormholes. It is highlighted how cinematography plunges us into possible temporal paradoxes or contradictions, but that we can reinterpret under the Novikov principle of self-consistency, explaining that the only possible events are the ones that don’t change the future. On the other hand, a mental exercise is developed with a billiard ball that travels to the past through a wormhole, to collide with its earlier itself, like the grandfather paradox. In addition, wormholes are analyzed from the point of view of General Relativity, and how they link to Einstein’s Field of Theory.
