In her Time Trader novels, Norton tacitly assumes that the physics of time travel differs so significantly from the physics of space travel, especially hyperdrive-propelled interstellar flight, that a civilization that discovers the technology of one simply will not discover the technology of the other.[citation needed] Earth’s physicists have discovered the secret of time travel, but the engineers and scientists who built and use the time transporters have devised a clever way to obtain the secrets of space travel: if it is not possible to discover the secrets, we get them from someone who did.
