The Flash Part II - The Inception of Spacetime in the Framework of HoloGenesis

Replacing the Big Bang narrative, The Flash is the name given to the inaugural event of HoloGenesis because of its extreme suddenness: the condensation of the first standing wave, the subitron, within the minimal sustaining interval of 6.25 × 10⁻¹² seconds. In that infinitesimal instant, spacetime itself stood forth, and the process has never ceased — the Flash is both the event and the continuing act of presence that sustains the lattice to this very day. It is called a “flash” not only for its speed but because it immediately gave rise to flashes of further coherence: tips inscribing themselves either by wrapping into vortex-like shells or by gliding as radiations. These first interactions unleashed the Rayleigh–Taylor-like cascades of Divalence and the decomposition of frequency into new particles, waves, and luminous emissions. The Flash thus names both the primal irruption of spacetime and the structural radiance that followed, making light, coherence, and matter inseparable from the very origin. The subitron is not a particle in motion, nor a shell, nor a glide. It is the first standing wave: the ontological hum projected within the span of admissible vibration, emerging not at the extremes but near the logarithmic middle between the symbolic minimal emission f¹ ≈ 1 Hz and the maximal compression f_void ≈ 1.10 × 10²⁷ Hz. Stabilized at the floor frequency f_cloud ≈ 1.60 × 10¹¹ Hz, the subitron condenses into a resonance with sustaining interval t_cloud ≈ 6.25 × 10⁻¹² seconds and wavelength λ ≈ 1.87 mm, which constitutes the finite size of the universe at its inception. Unlike derivative particles, which glide or wrap, the subitron is stationary presence: a transparent standing wave that produces no reflection and no emission, and thus casts blackness. In aggregate, trillions of subitrons compose the dark-cloud lattice that physics identifies with the CMB field, explaining ontologically why space appears as darkness. Because it is a blurry, hexahedral, bubble-like resonance, the subitron is both unit and fabric: the minimal harmonic whose curvature dovetails seamlessly with its peers, yielding the continuous lattice of spacetime. From inception it is gravitational, not as an external force but as curvature inscribed into its very form. Its black, blurred presence is therefore not void but coherence itself, the visible blackness of structure that sustains the cosmos. Thus the subitron is at once the seed of spacetime and the reason for its appearance. It defines the universe’s finite extent within a frequency span whose boundaries are not physical walls but ontological horizons: stillness forbidden below, compression enforced above. In its standing, coherence ceases to be abstract and becomes the very backdrop of existence. The subitron is the first harmonic of being — both resonance and lattice, presence and gravity, backdrop and fabric — the primal unit through which the universe first became real. © 2025 Grégoire Mommaerts, HoloGenesis.
