Pulse Domain

The Pulse Domain (⥂◉) is the whole new dimension of dimensions a null well's rupture opens: the universe as we see it, holding everything it will become, its space, its data lattice, its time and its spacetime. A universe is one Pulse of its own (the Pulse Mirror), and its Pulse Domain is the dimension that Pulse opens and fills. The Alpha note sounds in it, and its Harmonics, Harmonic 1 space, Harmonic 2 the data lattice, Harmonic 3 the physical, Harmonic 4 spacetime and every Harmonic Nova after, are that domain's overtones, not separate dimensions stacked one on another. Its core is the Pulsecore; at its centre is the Nullcore, the parent's null, null in every dimension the domain holds, and round it the Null Vacuum. Its physical part is the domain less the Nullcore (the Physical Domain). The name is the author's (2026-11-14): the base dimension of a universe, long part of the vision and named at last; its symbol joins the pulse ⥂ and the dimension ◉ of the book's symbols. It connects to Nullcore, Pulsecore, Null Vacuum, Pulse Mirror, Alpha String, Data Harmonics, Physical Domain, Pulse Domain Radius and Rupture Rule.
