      space elevators

      i remember doing a bit of math around space elevators a year ago and figuring out that if you make a cable hang from outer space to Earth, then the tensile strength is not strong enough to carry the weight of the cable itself. if you use any materials available today such as steel or carbon nanotubes. how would magnets change this?
