I read the article (in Swedish! There's also Google Translate for others with some odd translations). I find it plausable that space is filled with a plenum of polarizable particles, like Wal Thornhill has described. However, I'm still not convinced about their method and conclusion in this experiment:Bengt Nyman wrote:Exciting news about making photons out of Sii.
Experiments at the Chalmers Institute of Technology in Gothenburg, Sweden have managed to make photons out of "nothing". The results of the experiments support the speculation that under the right circumstances free floating energy strings can be stimulated into forming stable, cooperative balls of energy, in this case photons.
Due to physical constraints, instead of using a fast-moving physical mirror for mirroring (and "pushing") the virtual photons into detectable wavelengths, they use an electric discharge column that is controlled back and forth at 0.25 c with use of an magnetic field. "The discharge then works as a mirror for microwaves".
Then how exactly do they know that they simply aren't initiating the photoelectric effect of the surely not-perfect vacuum in this experiment? I.e. some random particles in the medium are hit by the electric discharge/jet which in turn excites (real) photons. Conventiently, they couldn't use this experiment to initiate other particles (as otherwize according to the theory) due to energy requirements, but that may as well be due to the photoelectric effect not exciting other particles than photons in this scenario.
