ah...I wonder...the theory on paper would be, but with the unknown comes the unknown. So will the theory rise up off paper to become a known or constant? Truth is if the magnetism would be able to condense or fold, I agree would be grand, but with the universe electrically charged the answer would most likely be magnetism or some similar form, again I agree. Can the theory be made to rise up off of paper? Don't know if anyone has tried.
A thought I have had for years but don't have the knowledge backround to discuss, much less pursue, is to use the natural magnetism of the universe, even if it is gravity, much like this prcess proposes. It seems to me we should be able to use the attraction/repulsion forces of the planets to power and guide a vehicle. Attraction forces in the direction of travel would be amplfied and employed as well as the repulsion forces of the planets behind.
Just a thought.
