Schumann resonances theory

Schumann resonances are natural electromagnetic vibrations occurring in the Earth's atmosphere, primarily between the Earth's surface and the ionosphere. These resonances are caused by lightning strikes that generate radio waves, which bounce around the planet nearly instantaneously. The interference of these waves produces specific frequencies, most notably around 7.8 Hz, similar to a resonant groove in the Earth's electromagnetic cavity. These signals are stable and can be influenced by global phenomena like solar activity, serving as a sort of atmospheric heartbeat that helps scientists study Earth's electrical environment and changes in weather or climate patterns.
