The Schumann Resonance

The Schumann Resonance, named after German physicist Winfried Otto Schumann, refers to the Earth's natural electromagnetic resonance frequency. It is created by the voids between the Earth's surface and the ionosphere, a layer in the upper atmosphere.
The Schumann resonance consists of several frequencies, but the main frequency is typically around 7.83 hertz. This value is the fundamental resonant frequency, considered the dominant rhythm of the planetary electromagnetic field.
The Schumann Resonance was originally discovered by Schumann himself when he was studying the electromagnetic waves in the atmosphere. These natural electromagnetic oscillations are caused by lightning that occurs constantly around the world, turning the Earth into a kind of resonance chamber. The Earth and the ionosphere act as conductors, reflecting electromagnetic energy back and forth between them.
Many people consider the Schumann Resonance to be important to life on Earth, as some research suggests that these frequencies may have effects on well-being and biological processes. Some claim that they are linked to the natural rhythms of the human brain and may play a role in our psychological and physical state, although this still needs further scientific research.
It is important to note that in recent years the Schumann Resonance has become the subject of increasing attention and even speculation about potential effects on human condition and consciousness, but scientific research is still ongoing in this area and many of the claimed effects are subject to change further investigations.
