The invention of Muir’s tape-mass engine carried early explorers out as far a-s Jupiter; and gravity was discovered though it had been postulated centuries before-by the 2018 Jovian expedition, the last space flight with Muir engines which was completed on behalf of the West before that culture’s final extinction. The building, by remote control, of the Bridge on the face of Jupiter itself, easily the most enormous (and in most other respects the most useless) engineering project ever undertaken by man, had made possible direct, close measurements of Jupiter’s magnetic field. The measurements provided final confirmation of the Blackett-Dirac equations. which as early as 1948 had proposed a direct relationship between magnetism, gravitation, and the rate of spin of any mass. Up to that time, nothing had been done with the Blackett-Dirac hypothesis, which remained a toy of pure mathematicians. Then, abruptly, the hypothesis and the mathematicians had their first innings; From the many pages of symbols and the mumbled discussions of the possible field-strength of a single electronic pole in rotation, the DillonWagonner grávitron polarity generator-almost immediately dubbed the “spindizzy” in honor of what it did to electron rotation-sprang as if full-born. The overdrive, the meteor scree
