Schumann ResonanceEarth's electromagnetic heartbeat — 7.83 Hz.
The fundamental Schumann resonance is the standing wave between the Earth's surface and the ionosphere, sustained by lightning. It pulses around 7.83 Hz — roughly the same frequency as human alpha brainwaves.
How to read the chart
The spectrogram shows time on the horizontal axis (most recent on the right) and frequency on the vertical axis. Color encodes power: cool colors (blue/green) are quiet, warm colors (yellow/red) are active. The fundamental at 7.83 Hz is the bottom-most band; harmonics ride above it (~14, 20, 26, 33, 39 Hz).
Bright streaks above the baseline are spikes — moments of unusually high power. Their interpretation is debated, but they're consistently noticed during major solar storms, large geophysical events, and (some say) collective emotional events.
What it is
Discovered by physicist Winfried Otto Schumann in 1952, the resonance is sustained by the ~50 lightning strikes per second happening around the planet. The Earth-ionosphere cavity rings like a giant spherical bell, with the lowest mode around 7.83 Hz.
It's stable on short timescales but slowly drifts — the historical baseline of "around 7.83" has been measured higher in recent years, though the long-term trend is still a subject of active research.
Why some pay attention
Human alpha brainwaves run between 8–13 Hz. The proximity to the Schumann fundamental has fueled long-running research and speculation about coupling between the planetary EM field and human nervous systems. NASA studies have established that astronauts deprived of the Schumann resonance experience health and mood disturbances; the International Space Station now includes a Schumann resonance generator to maintain it.
Spikes worth knowing
Recorded resonance power spikes have correlated with major solar events, large earthquakes, and significant collective moments. The "white spikes" visible on the spectrogram are interpreted by some as field-level events — though the scientific consensus is more cautious.
