Hyperdrive

The idea of ​​a hyperdrive in most science fiction works is based on the assumed existence of spatial dimensions adjacent to real three-dimensional space. Such additional dimensions are most often called hyperspace (although other names are also used). After the hyperdrive is launched, it transfers the spacecraft to this hyperspace, in which the spacecraft can travel great distances in less time than the spacecraft can cover the same distances in ordinary space. When a ship reaches a point in hyperspace corresponding to its destination in ordinary space, the ship leaves hyperspace and returns to ordinary. As a rule, a hyperdrive is referred to as a way to speed up travel, which takes a lot of time in ordinary space. Instantly or quickly covering distance through hyperspace is called hyperspace .

Artistic descriptions of the ability of ships to move in outer space faster than light often accompany the storylines of novels, television broadcasts and films in which they are mentioned. The distance in hyperspace can be less than the present or geometrically inverse to it, which allows the ship to move through hyperspace to increase the speed of the ship by reducing the distance and time required to move. It is also possible that the speed of light in hyperspace is not a limit of the speed of bodies, like real space, so ships traveling in hyperspace are likely to exceed the speed of light, appearing at the destination much faster and without the relativistic time dilation predicted by the special theory of relativity (STR).

Usually in hyperspace, spaceships are isolated from the real universe. They cannot communicate and interact with the real world until they appear in it. Often, if two ships are in hyperspace, then they cannot interact with each other. For people traveling in hyperspace, time flows as usual - with or without a slight time dilation . 24 hours in hyperspace equals 24 hours in the real world. This is due to the fact that a typical description of a hyperdrive includes only a change in the position of the spacecraft without changing its speed, that is, the ship appears with the same momentum, kinetic energy and direction of motion as when entering hyperspace, thereby avoiding relativistic phenomena . The exception is the David Brin Exalted Saga , where hyperspace is divided into “levels” at which time flows at different speeds. Hyperspace itself can be depicted as swirling colors, fast moving stars, or something that can drive a person crazy if he looks at him with an unaided look.

In most science fiction, hyper-jumps require careful thought and calculation, since any mistake can lead to irreparable consequences. Thus, jumping can be a much shorter distance than it would be possible for the navigator to “look around”: determine the position of the ship, calculate the next jump. The time spent traveling in hyperspace also varies. Travel time can take hours, days, weeks, or more. Such cases can serve as a beginning for a story that takes place over a very long journey.

In Star Wars , hyperspace travel is shown to be possibly dangerous because of the likelihood of passing a route near a celestial body with a strong gravitational field, such as a star or a black hole . In such cases, if the spacecraft, being in hyperspace, passes too close to the source of strong attraction, then the ship is pushed out of hyperspace and returns to normal space or collapses. Consequently, some routes in hyperspace can be designated as safe, not passing near stars or other dangerous objects. In other science fiction works, hyperspace travel can occur outside of ordinary space, for example, in subspace, as in Stargate: SG-1 .
