• from wikipedia: Schumann resonances
  The Schumann resonances (SR) are a set of spectrum peaks in the extremely low frequency (ELF) portion of the Earth's electromagnetic field spectrum. Schumann resonances are global electromagnetic resonances, generated and excited by lightning discharges in the cavity formed by the Earth's surface and the ionosphere.

• Schumann resonance is a phenomenon that occurs in the atmosphere around the earth.
  More precisely, it occurs in that space between the earth and the ionosphere,
  that space which is filled by our atmosphere.
• It is initiated by lightning strikes around the world,
  and is sustained by the fact that the earth and atmosphere and ionosphere
  together act like a giant waveguide. (capacitor?)

• A waveguide is an electrical component,
  composed of a cavity, or enclosed space

• What you have is a ball, a sphere,
  which is composed of a lot of iron, conductive,
  and a lot of salt-water, also conductive,

• and then there's a layer of atmosphere,
  mostly nitrogen and oxygen,
  which is not generally going to conduct,
  (though a lot of water content in the atmosphere
  can indeed conduct)

• and then there's the ionosphere,
  a cloud of - also conductive - ionized gas molecules

• In fact, it happens that lightning, wherever around the world,
  will put a wide-band electromagnetic impulse into the wave guide
  that will "echo" everywhere in the 3 dimensions around the surface of the Earth.

  • In any case, you end up with the space between the layers becomes a resonant cavity,
    and easily transmits resonant frequencies.

  • and ... people have receivers tuned to those resonant frequencies,
    so they can calculate the resonant frequencies,
    and it turns out that one [the most?] prominent frequency
    is 8-11 Hz,
    which is exactly the same frequency as brainwaves during alpha meditation.

  • One might think, that if one wanted to "get into", live-in-harmony-with, the Earth,
    one might facilitate that by "synching" in with the Earth's natural frequencies, like 8-11,
    by spending time IN that frequency, by the practice of alpha meditation.
    This is a meditation, a learning of how to use our minds,
    that can be learned by bio-feedback techniques
    that produces high brainwave output in 8-11 Hz.

    Schumann Resonance

    At any given moment about 2,000 thunderstorms roll over Earth, producing some 50 flashes of lightning every second. Each lightning burst creates electromagnetic waves that begin to circle around Earth captured between Earth's surface and a boundary about 60 miles up. Some of the waves - if they have just the right wavelength - combine, increasing in strength, to create a repeating atmospheric heartbeat known as Schumann resonance. This resonance provides a useful tool to analyze Earth's weather, its electric environment, and to even help determine what types of atoms and molecules exist in Earth's atmosphere.

    The waves created by lightning do not look like the up and down waves of the ocean, but they still oscillate with regions of greater energy and lesser energy. These waves remain trapped inside an atmospheric ceiling created by the lower edge of the "ionosphere" - a part of the atmosphere filled with charged particles, which begins about 60 miles up into the sky. In this case, the sweet spot for resonance requires the wave to be as long (or twice, three times as long, etc) as the circumference of Earth. This is an extremely low frequency wave that can be as low as 8 Hertz (Hz) - some 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 at the perfect spot such that the crests and troughs are aligned. Voila, waves acting in resonance with each other to pump up the original signal.

    While they'd been predicted in 1952, Schumann resonances were first measured reliably in the early 1960s. Since then, scientists have discovered that variations in the resonances correspond to changes in the seasons, solar activity, activity in Earth's magnetic environment, in water aerosols in the atmosphere, and other Earth-bound phenomena.

  • in fact, in another post,
    it's reported that deprivation of alpha frequencies
    can have negative affects on our mental and physical health.
