Sternportals

Sternportals are a fictional concept, primarily appearing in science fiction narratives, that describe a type of advanced transportation technology. The term "sternportal" itself suggests a connection to the rear or back of something, perhaps implying a limited or specific directional capability. In many fictional universes, sternportals function as doorways or gateways that allow for the instantaneous or near-instantaneous travel between two distinct locations. These locations can range from within the same spacecraft to vast interstellar distances.

The mechanics behind sternportals are typically explained through speculative science, often involving exotic matter, wormholes, or manipulation of spacetime. Unlike more general portal systems, sternportals might be fixed to a specific departure and arrival point, or they could be mobile and deployed as needed. Their primary advantage lies in overcoming the limitations of conventional travel, such as speed of light barriers. However, fictional depictions often include limitations or risks associated with their use, such as energy requirements, potential instability, or the possibility of arriving at an unintended destination. The precise nature and capabilities of sternportals vary significantly depending on the specific fictional work in which they are featured.
