Traveling Through Wormholes
In physics, a wormhole is a hypothetical topological feature of spacetime that would be, fundamentally, a “shortcut” throughspacetime. For a simple visual explanation of a wormhole, consider spacetime visualized as a two-dimensional (2D) surface. If this surface is folded along a third dimension, it allows one to picture a wormhole “bridge”. There is no observational evidence for wormholes, but on a theoretical level there are valid solutions to the equations of the theory ofgeneral relativity which contain wormholes. Because of its robust theoretical strength, a wormhole is also known as one of the great physics metaphors for teaching general relativity.
