I've always suspected that anti-gravity would eventually be discovered thru work with magnetics. Especially since we already have limited anti-gravity now with mag-lev.
So, if you open a story in nextbigfuture.com, and then go to the left sidebar of topics, go down and open the topic on SPACE AND NANO-TECH. You will find some short but fascinating data out of the NIAC (NASA Institute for Advanced Concepts). Go down to "References for Space Related Predictions", then to "Current Work on Ion Engines", and you will find data on:
-- The NIAC study on collecting antimatter that is in the magnetic fields of planets. And the NIAC studies on efficient systems for using anti-matter for propulsion.
-- Also discussion on how sufficiently strong magnets would allow for a ground launched system that pushes against the magnetic field on Earth. Mainly by using room temperature superconductors.
-- Sailor B., they also mention your space elevators and tethers.
