Exploration de la cosmologie DEBA : un univers qui émerge de la cohérence organisationnelle, sans postulats préalables

DEBA Deterministic Emergence by Actualization

Every cosmological theory requires a starting point. In the standard model, that starting point is a spacetime singularity — the Big Bang — within a spacetime already endowed with a metric and causality.

DEBA proposes a more radical break: before any physics, there is no space, no time, no geometry, no causality. There exists only
an abstract, purely formal substrate, which we call the Primordial Void.

This Void is not an ordinary physical vacuum (no vacuum energy, no quantum fluctuations in the usual sense), but a space of possible configurations endowed with a statistical measure.

Physics will emerge later, through coherence condensation.

Lunar Formation via Triple Phase Transition in the Differentiating Proto-Earth

The origin of the Moon remains one of the open questions of planetary science. The

canonical giant impact model (Theia collision) predicts neither the near-isotopic

identity of Earth and Moon, nor the crustal dichotomy, nor the ≈300 Myr delay of

the terrestrial dynamo. The synestia model faces similar limitations. This work

proposes a conceptually distinct alternative — an entirely internal mechanism

requiring no external impactor and no synestia — grounded in a necessary

thermodynamic observation: any Earth-mass planet emerges from accretion in a

state of near-total melting (Egrav exceeds the mantle fusion energy by a factor of

155). The proto-Earth is therefore necessarily a rapidly rotating magma sphere

(Trot ≈5h), without a stabilizing satellite, evolving in a permanently

out-of-equilibrium Hadean environment — silicate atmosphere at 2000–4 000K,

T-Tauri Sun, active residual bombardment — for 30 to 50 million years.

In this context, Moon formation results from a Triple Phase Transition driven by

the progressive segregation of Fe-Ni. The chaotic wobble of the rotation axis in the

co-rotating body frame — sustained by continuous Hadean perturbations —

generates toroidal ows that enter elliptical parametric resonance with the inertial

modes of the uid [Malkus, 1968, Kerswell, 2002, Lacaze et al., 2004]. The resulting

growth rate σres = Ωf/2 (linear regime) brings the Coherent Magmatic Torus

(TMC) to the bifurcation velocity Ucrit ≈9.8km s−1in ≈32 hours. Three coupled

transitions produce N= 2–3cohesive ejection episodes in 3–4 weeks and a Hadean

dynamo delay of 290–360Myr [Tarduno et al., 2015, 2025]. The model formulates

ten quantitative and falsiable predictions. The central prediction — seismic

interface at d≈200–315 km, impedance contrast |R| ∈ [0.01; 0.04] — is testable by

Chang’e 7, a mission designed to probe lunar internal structure with a broadband

seismometer at the lunar south pole (August 2026). The geochemical predictions

are testable by Artemis III (2028–2029), a mission that will collect mantle materials

from the South Pole-Aitken basin — the deepest and oldest impact structure on the

Moon. This deposit pre-registers the theory and its predictions prior to these

mission data.
