How can one get in touch with Eugene. Something about my own
project, I wish to discuss with him.
Thanks
Far-fetched? Indeed. Most physicists laughed at Podkletnov's report. Riley Newman, a professor of physics at UC Irvine who has been involved in gravity research for 20 years, typified the reaction when he commented, "I think it's safe to say gravity shielding is not conceivable." Like many scientists, he felt that Podkletnov must have made a mistake, measuring magnetic fields or air currents instead of genuine weight reduction. And yet, few of Podkletnov's critics actually bothered to read his description of his work. Their reaction was so dismissive, it almost sounded like prejudice. From their perspective he was an outsider, a nonmember of the "gravity establishment." They couldn't believe that a major discovery in physics had been made by such a no-status dilettante fooling around at some obscure lab in Finland.
After publishing a preliminary paper in 1992, he wrote a more thorough paper that was rejected by more than a dozen journals till finally it penetrated the peer-review process at the respected British Journal of Physics-D. This seemed to offer the recognition he was hoping for, yet instead it initiated a career-destroying nightmare. The trouble started when Robert Matthews, science correspondent to the British Sunday Telegraph, got hold of the story. Matthews, like any journalist, relies on contacts, and he's disarmingly honest about it. "You don't get stories by digging for them," he now says with a laugh. "This isn't like Sherlock Holmes, that's a lot of bollocks. It's like, you hope a little brown envelope turns up in the post, and if it does, you're in luck." In his case the little brown envelope contained page proofs of Podkletnov's paper, leaked by a man named Ian Sample who worked on the editorial staff of the Journal of Physics-D. Although Podkletnov's paper hadn't been published yet, Sample and Matthews decided to break the story in the Sunday Telegraph, which printed it on September 1, 1996. The first sentence was key: "Scientists in Finland are about to reveal details of the world's first antigravity device."
Antigravity? Podkletnov never used that word; he said he'd found a way to block gravity. Maybe this seemed a trivial distinction, but not to the staid professors at the Institute of Materials Science in the University of Tampere, to whom "antigravity" sounded like something out of a bad Hollywood movie. The director of the institute promptly denied any involvement and declared that Podkletnov was working entirely on his own initiative. Then the coauthor of Podkletnov's paper claimed that his name had been used without his knowledge - which was highly implausible, but he stuck to his story, presumably because the institute told him to. In the end Podkletnov had to withdraw the paper from publication in the journal, he was abandoned by his friends, and his credibility was impaired.

Mr Podkletnov said something that contradicts the theory of General Relativity. In video 3, he says that the speed of gravity waves are 64 times greater than the speed of light.
This goes against the theory of General Relativity. Anything that moves faster than light can send a signal to the past and create logical paradoxes.
Anyone knows anything about this?

As a professional, theoretical physicist (M.A., M.Sc., Ph.D.), having heard here Dr Eugene Podkletnov's explanation of the loss of weight of objects suspended over his spinning, superconducting ceramic discs, I can say with full confidence that he does not know what he is talking about. Or, to be more accurate, he is a low-temperature physicist who seems to have little understanding of fundamental, theoretical principles and particle physics (my research field) - a quite common occurrence amongst such experimentalists, in my experience, unfortunately. Whilst, according to Einstein-Cartan theory, spinning matter would generate a torsion component in the space-time connection and a repulsive, gravitational force in addition to the normal, attractive component, the speed of rotation is far too low for the angular momentum density to create even a 5% change of weight (the calculations are too long and technical to add here). So the effect is not due to generation of torsion in the space-time metric.
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.

Good point although the concept itself of anti gravity is not allowed by GR, and if anti gravity exists and in fact it does , shows that GR is flawed

Perhaps GR is flawed: it allows wormholes, which means that faster-than-light travel is possible.
Suppose Bob and Alice are connected through a wormhole and also have a conventional communication device. Wouldn't this configuration allow for paradoxes? it would, according to the various sites online.
For me, faster-than-light travel does not have to create paradoxes. It might be possible to witness the effect before the cause, but you can't interact with the cause in order to change the effect.
Originally posted by Angelic Resurrection how was he able to interact with this worm hole and indeed measure their speed and come to a figure of 64c.

THAT is a very good question.. unfortunately we can't ask him

I also found some news about Podkletnov: looks like is going to start a 50 mln $, 5 year program together with a dozen of physicists about this topic. And he's going to publish something "cool" in october, 2011.
Sorry, no links, just "rumors".
