Subspace jump

Subspace jump has replaced the photon engine used in human spaceships in the 21st century. This technology is based on the subspace physics and uses the "wrapping" of traditional space in order to achieve a condition in which a material body, e.g. a spaceship, is "stretched" between two points in space for a short time. This has nothing to do with traditional space travelling and is much more like teleportation but unlike  null-T  it is not applicable on a planet surface because of some technical restrictions.
