- A ship using this technique travels very close to the speed of light, without actually reaching light speed. Since time would compress for the crew, they would age very little, even on a long voyage. However, the rest of the universe would age at normal speed, including everyone they left behind on Earth. Depending on the length of the voyage, the crew's family and friends may be long dead when the ship reaches its destination. See Propulsion.
