Hey all, So I've been writing a hard science fiction novel and need real answers from someone who understands the fields better than I ( I have no formal education outside basic highschool classes in physics) The problem I have is I'm not a fan of faster than light travel but I need a way for the explorers to travel great distances quickly. My idea is this: A precision magnetic field, or simply a "beam" that is pointed at a corresponding station and the resulting magnetic attraction pulls the craft towards it. I have no idea if that sort of thing is possible. So I would like to know 1) How fast is magnetic attraction for extremely powerful magnets? And would those speeds offer the explorers the ability to travel great distances in a reasonable time frame? 2) Is a "precision magnetic beam" even theoretically possible? 3) What sort of calculations can I use to make the technology seem realistic? 4) If a system like this existed, would it affect any planetary magnetic fields? 5) A zero g environment means the system would only need to ping it's target station to retain it's speed, which removes the necessity for vast amounts of combustible fuel, but how could they slow down effectively without hitting the planet or the station? I apologize if I put this in the wrong section, again I'd really like some input on this from people who understand it better than I. Any help is Aprreciated. Thanks again. -Theron.
