@JD The Confused,
Of course a quarter of the size of the earth is still really large what if we had an inside to the magnet that either spins the opposite direction of the outside at the same speed that would increase relevant speed to maybe obtain what we need specially for a smaller mass at greater speeds and if it does produce gravity which is what we want then we can effectivly utilize gravity which is something most people dreamed of in shows and what we consider science fiction...maybe science fiction isnt so far out there anymore...it will take people with imagination to move this world out of the era of living comfortably with the unknown
