An advanced problem in special relativity is to consider a spaceship leaving Earth accelerating at g = 9.8 m/s² so the passengers “feel at home,” and to determine both the "Earth-time" and “ship-time” for journeys to far-off destinations. The solution necessitates some rather complex integration that is beyond the scope of introductory astronomy, however a simpler expression for the result to be written for the “ship-time” as a function of the distance traveled, traveled that can be used in an introductory course. Calculations show that relativistic spaceflight could someday make the universe accessible (at least for those who go on the trip). Of course, maintaining an acceleration of g for any extended period of time would require much more power than we are capable of generating, perhaps even in our most futuristic fantasies about starships, some of which can make an interesting addition to the discussion.
