Starfarers And The Time Patrol
macroscopic time travel is possible - people can go;
past events can be changed;
a post-human Danellian confirms that the purpose of the Patrol is to prevent random changes, which would preclude life or consciousness.
subatomic time travel is possible - information can be sent;
past events cannot be changed;
a message from the future confirms that the interstellar drive stabilizes the universe.
Thus, in Starfarers, interstellar travelers fulfill a cosmic role similar to that of Time Patrollers. Among its many other qualities, Starfarers is a contribution to the theory of time travel.
