The answer of the scientific community
Kirlian photography should remain in the paranormal realm and should never be utilized as a tool in diagnosing or treating diseases. The halo-like appearance around photographed objects could not be accepted as the physical expression of auras but a manifestation of a physical phenomenon.
Scientists explained that the seemingly eerie color that appears around the photographed objects is the inevitable result of the interaction of humidity, temperature, pressure, electrical grounding, and light waves. The phenomenon is parallel to the mirage effect. For example, a body of water at the center of the road during a hot humid day. There is, of course, no water on the road, even though the eye is convinced of seeing an image of what seems like a body of water.
Scientists are also dubious about the use of Kirlian photography in the field of medicine. It is not similar to diagnostic tools such as MRI or tomography. And the reason is quite simple: images of so-called auras from Kirlian photography are not reliable. Reliability is a major requirement of all scientific phenomena. Without reliability, no hypothesis can graduate into a scientific theory. This is why scientists value scientific experiments that are carried out under controlled settings.
Images from Kirlian photography could not produce the same so-called auras. At the same time, the self-proclaimed clairvoyants and supernaturally gifted, could not have a consensus about the color of a particular person’s aura at any given time. How then, can the images of Kirlian photography (if auras are real at all) be used reliably in the field of medicine? Until the arguments of the scientists are answered satisfactorily, the technique of Kirlian photography remains a paranormal hocus-pocus.
