Schumann Resonance: Does Earth's 7.83 Hz "Heartbeat" Influence Our Behavior?
The ionosphere is the region of the Earth's atmosphere that stretches roughly from 30 to 620 mi (50-1,000 km) above the surface and, along with the upper atmosphere, forms a boundary between Earth's lower atmosphere and the vacuum of space.
Between the Earth's surface and the ionosphere is a cavity containing a total electrical charge of 500K Coulombs. There is a vertical current flow between the ground and the ionosphere. The atmosphere has a resistance of 200 Ohms and a voltage potential of 200,000 Volts.
It means that there is a great deal of electrical activity between the surface of the Earth and the ionosphere. Some of this is in the form of standing waves of electricity. These standing waves are known as Schumann Resonances. So what are these resonances?
Each lightning burst creates electromagnetic waves that begin to circle Earth in the cavity between Earth's surface and the ionosphere. Some of the waves — if they have just the right wavelength — combine and increase in strength to create a Schumann resonance. The 'sweet spot' for creating this resonance is when the wave is as long or longer than the circumference of Earth. This is an extremely low-frequency wave of up to one hundred thousand times lower than the lowest frequency radio waves used to send signals to your AM/FM radio. As this wave flows around Earth, it hits itself again in such a way that the crests and troughs of the wave are aligned and act in resonance with each other to increase the original signal.
The base atmospheric electromagnetic resonant frequency is 7.83 Hz. This means our atmosphere is continuously resonating with a radio frequency of 7.83 Hz, along with progressively weaker harmonics at around 14.3, 20.8, 27.3, and 33.8 Hz. These oscillations are called the Schumann resonances.
