Hi Mike,
you are raising an interesting question. These gravity shielding
experiments have been performed by Podkletnov and coworkers at Tampere
University in Finnland, 1996 or so. They claimed that they would have
reduced the gravitational field above a spinning high temperature
superconductor. At that time nobody believed them. And Podkletnov even had
to leave the university. In the meantime there has been some theoretical
efforts to describe gravity shielding, above all by the Italian physicist
G. Modanese. There is a collaboration in the states trying to reproduce the
experimental results of Podkletnov. The experimental setup is very involved
and it is hard to fabricate all the needed device, for example the
superconducting disk. As long as Podklednov's results have not been
reproduced by independent scientists and all possibilities that other
effects may be responsible for what looks like a gravity shielding have
been studied one cannot be sure.
Search also our archives for
