First you failed to see that radiometer referenced above is working on a totally different principle. I thought I just toss it up to see if anyone notices. Second there is a large difference between physics and mathematical masturbations. Such as for example 3D projections of 2D screens forming a new theory of gravity, spaghetti alias string theory, models that say break even fusion in a Tokamak will work if you make it big enough, models that predict 'gravity waves' and keep looking and every year find a new maximum... Models of the meson neutron that do not seem to *quite* work out in practical experiments. I must say that maybe Feynman was right with QED, but on the other hand I found his papers very disappointing. Math masturbations, tons of paper full of those each year on the archivex server, in journals, no that is not physics. A solar sail *IS* physics, it really flies, and the math can be done by mere mortals. So, get a clue, buy one or rent one, you will need it to do anything more useful then trying to show your limited knowledge here.

If 'solar sails' work, then the sun's energy would have pushed the planets out of their orbits billions of years ago, and we would all be... dead. Photon exchange (not graviton exchange) is the mechanism of gravitational ATTRACTION. The Crookes Radiometer rotates black squares trailing consistent with photons being an attraction. Read my post explaining about radiometers to understand how my New Science correctly explains most that you figured was already explained, but was wrong.
