0.5 → 0 · An interactive metaphor, not an EEG scale
Event Horizon · Where measurement ends and inquiry begins
0.5 Hz is not the end of brain activity, and 0 Hz is not a ‘frequency of death.’ EEG-band boundaries are useful analytic conventions; from here the descent becomes a metaphorical room that moves from a countable rate into silence, uncertainty, and meaning.The zero room · An interactive metaphor
The point that becomes a question
The first pulse moves at an illustrative 0.5 Hz, inviting you to feel the threshold between motion and stillness.

In physics, an event horizon is a boundary beyond which a signal cannot reach an outside observer, it is not the centre of a black hole.

Experience / metaphorDesign metaphor
The room borrows the event horizon's one-way-boundary idea to stage a moment when collecting answers stops and staying with a question begins.

0 Hz, silence, physical vacuum, and philosophical ‘nothingness’ are not the same thing.
