Scientists led by Victor Pasko have uncovered the precise atmospheric chain reaction that triggers lightning, revealing how electric fields in thunderclouds accelerate electrons, produce X-rays, and initiate lightning through a cascade of high-energy photons and electrons, explaining phenomena like terrestrial gamma-ray flashes and their often dim optical and radio signatures.
