Evgeny Podkletnov’s antigravity technology may sound far-fetched, but it’s attracting serious interest from the likes of NASA and Boeing. Russian scientist Evgeny Podkletnov is challenging one of the most sacred tenets of physics — the law of gravity. Podkletnov claims that when objects are placed above a high-temperature, superconducting ceramic disk rotating within an electromagnetic field, the objects lose as much as 2 percent of their original weight. He calls the effect “gravity shielding,” and when word of his research reached the public in 1996, a brief media circus ensued. Many in the physics community dismissed his effort as wishful thinking.
