Nope those papers that I referred to were examining the possibilities of getting FTL travel assuming relativity to be correct. -- Steve O'Hara-Smith | Directable Mirror Arrays C:>WIN | A better way to focus the sun The computer obeys and wins. | licences available see You lose and Bill collects. | http://www.sohara.org/

However the trajectories will differ from those produced by general relativity even if you are dealing with nanograms of mass and relative speeds of a few microns per millenia. It's just that the differences will be very small - too small to measure most of the time. > But if you want to calculate the orbit of Mercury around the Sun with > great precision for the next umpty-ump years, better use Einstein. > Newtons Laws can be derived from Einstein anyway, as a special case > where gravity is weak (i.e. not near a body the mass of the Sun or > greater). They come out as a limiting case as speeds and gravity tend to zero, they're never an exact match. However the thing that invalidates a theory is not a newer theory but rather experimental evidence that contradicts the predictions of the theory. One repeatable experiment in which momentum was not conserved would invalidate most of theoretical physics even if nobody ever managed to create a theoretical framework to contain it. -- Steve O'Hara-Smith | Directable Mirror Arrays C:>WIN | A better way to focus the sun The computer obeys and wins. | licences available see You lose and Bill collects. | http://www.sohara.org/
