Wormholes and cosmic strings could potentially be used for time travel from "summary" of Time Travel in Einstein's Universe by J. Richard Gott
Imagine a shortcut through spacetime that could take you from one point to another almost instantaneously. This is the idea behind wormholes and cosmic strings, which are theoretical structures that could potentially be used for time travel. Wormholes are like tunnels that connect two points in space, allowing for travel between them in a shorter amount of time than it would take using conventional methods. These structures are predicted by Einstein's theory of general relativity, which describes how gravity affects the curvature of spacetime. If wormholes exist, they could provide a way to travel not only through space but also through time. Cosmic strings, on the other hand, are long, thin strands of energy that are thought to have formed in the early universe. These strings are also predicted by certain theorie...
