EXCERPTS: Researchers have created the first laboratory analog of the 'black hole bomb', a theoretical concept developed by physicists in the 1970s.
[...] physicist Yakov Zel'Dovich figured out that you didn't need a black hole to see this phenomenon in action. An axially symmetrical body rotating in a resonance chamber, he figured, could produce the same energy transfer and amplification, albeit on a much smaller scale.
Later work by other physicists found that, if you enclose the entire apparatus in a mirror, a positive feedback loop is generated, amplifying the energy until it explodes from the system.
[...] It doesn't, just to set your mind at ease, pose any danger. It consists of a rotating aluminum cylinder, placed inside layers of coils that generate magnetic fields that rotate around it, at controllable speeds...
[...] "The system satisfies the experimental conditions speculated by Zel'dovich for the observation of spontaneous generation and also the conditions outlined by Press et al. for black hole bombs," the researchers write in their paper... (MORE - missing details)
