What is really happening has nothing to do with altering gravity. It is far simpler than that. A magnetic field is generated by the currents of electrically charged Cooper pairs circulating in the surface of the rotating, superconducting ceramic disc, expelled from its interior by the Meissner Effect. This field couples to the atomic nuclei in the suspended object. Their intrinsic magnetic momentum makes them behave as minute magnets with their own magnetic fields, and it is the mutual repulsion between their fields and the magnetic field of the currents of Cooper pairs that causes the levitation, making it appear to lose weight. It is merely a form of magneto-levitation that exploits the natural diamagnetism of objects.
That is all I wish to comment on the topic.

Yes I agree. I would like to see how the loss in weight was measured. It may be in one of his papers somewhere, but to date have not found it

It's not easy to be a scientist here. Most of us have already given up all hope for doing anything "new".

Well maybe John Lear is right about anti-gravity. Maybe that's just because they have it all figured out already.

I would have to check, but I could swear that a simple scale was used, at least in Li's experiments.
How did Podkletnov accurately measure his claimed 2% weight reduction? Podkletnov used a mercury manometer which was placed above the disc. The manometer is similar to a barometer, and when placed above the superconductor, the disc recorded a 4-mm reduction in air pressure primarily to a reduction in the weight of the air. Podkletnov took his mercury manometer to a lab directly above the superconductor disk one story below. He found exactly the same result as if his experiment was generating an invisible column of decreased gravity extending upward indefinitely into space.
In 1996, Russian émigré scientist Eugene Podkletnov (PhD in the manufacture of superconductors) submitted a peer-reviewed article to the respected British Journal of Physics-D. In this article Podkletnov claimed that he could prove a defiance of gravity. When a London newspaper published Podkletnov’s work, the skeptics tore him apart. Einstein had proved that you could not defy the laws of gravity! Subsequently, Podkletnov withdrew the article and was evicted by his university. In 1996 he retreated from the public eye and relocated to Finland.
Few of Podkletnov's critics actually bothered to review his work. The majority of the scientific community couldn't believe such a major discovery in physics by such a no-status materials scientist fooling around at an obscure lab in Finland.
In 1990, before Podkletnov’s experiment, a scientist named Douglas Torr from the University of Alabama started publishing papers with a Chinese woman physicist named Ning Li. Together they predicted that superconductors could in fact affect the force of gravity. Podkletnov had accidentally validated their predictions. Torr and Li worked with the Marshall Spaceflight Center in Huntsville, where they eventually persuaded NASA to start a serious long-term investigation. Ning Li remained involved, while Douglas Torr relocated to South Carolina.
Although Dr. Podkletnov fires our imagination: In professional circles, he is still considered a hoax. Up front with this idea is Dr. Martin Tajmar, who is one of the worldwide leading scientists in this field and has often tried to re-enact the Russian's experiments. Every single time with a negative result: "If my name was Podkletnov, and I managed to prove a manipulation of gravity, why would I not call CNN and have them report it live instead of turning it into a little mystery for myself?"
Magnet levitates with the help of a ceramic and liquid nitrogen. Pretty cool. I did not perform this video. Its actually Professor Tom H. Johansen in the Superconductor Laboratory at the University of Oslo, Norway who performed it. Thank you Prof. Johansen for contacting me!

Angelic Resurrection,
So do you have an idea why that would be the case? I was implying a conspiracy with PTB behind who have already figured out the anti-gravity technology and preventing further research or discussion into the area.
Because you are right in a sense. Why would research into anti-gravity technology be any different than all the other fantastic areas being researched in universities today?
