"Wormhole" is a term used to describe a hypothetical portal through space-time that would allow matter to travel rapidly between two points. This concept is often used in science fiction as a way to bypass the limitations of traditional space travel. However, there are several other terms that can be used to describe similar phenomena. For example, an "Einstein-Rosen bridge" is a hypothetical connection between two distant points in space-time, while a "portal" refers to any gateway or opening that allows access between two distinct regions. Another term used in science fiction is a "stargate," which functions as a portal through which travelers can pass between different worlds and dimensions.
