...in the form of what may be an accidentally discovered artificial gravity generator, with possible practical applications!:
http://www.esa.int/SPECIALS/GSP/SEM0L6OVGJE_0.html If this effect is real, it's fully 1/10,000 G -- which is not to be sneezed at, and might conceivably lead us to Bigger Things. |

The actual paper ( http://esamultimedia.esa.int/docs/gsp/Expe...l_Detection.pdf ) says that the effect appears to be "directly proportional to the applied angular acceleration of thesuperconductor following our theoretical motivations" -- that is, the gravity generated is in direct proportion to how fast you spin the superconducting ring. Spin it at 65 million rpm and you'd generate a 1-G field. And -- to repeat -- the scientists involved apparently have rather bigger reputations than Poletnikov, and were researching a puzzling already-observed phenomenon in superconductors. IF this works out -- and, needless to say, that is an extremely big "if" -- the analogy to James Blish's "spindizzies" is rather eerie.
