The NTU (No Time Universe) research program has reached an important milestone with the publication of the first NTU Cosmological Genealogy Tree (refer to https://notimeuniverse.com/a-new-cosmology/ page).

Unlike traditional approaches that compare theories at the same conceptual level, the NTU genealogy tree proposes a different perspective: quantum gravity theories, cosmological mechanisms, and major physical transitions may not be competing descriptions of reality, but rather different stages in the emergence of our universe from a deeper primordial state.

The genealogy tree places the NTU at the origin of the cosmological sequence as an atemporal three-dimensional substrate composed of Planck-scale nodes and pre-links. From this primordial phase emerge, through successive rigidification and coarse-graining processes, causality, time, quantum geometry, fields, particles, and eventually the large-scale universe we observe today.

One of the main objectives of this work is to investigate whether several currently viable quantum gravity frameworks can be interpreted as intermediate descriptions of NTU evolution.

The first version of the genealogy tree includes:

• Inflation and the possible reinterpretation of the inflaton as an effective coarse-grained field.
• The emergence of a primordial electrophotonic field preceding causal rigidification.
• A possible ontological explanation for the massless nature of the photon.
• The photon–neutrino entanglement era and the emergence of the three neutrino families.
• The first causal rigidification phase and its convergence with Causal Set Theory.
• Quantum-geometric rigidification and its convergence with Loop Quantum Gravity and Spin Foam models.
• The emergence of spacetime and its relationship with Causal Dynamical Triangulations.
• Holographic projection mechanisms associated with the realization of physical events.
• Extended structures related to String Theory and Brane models.
• Continuum renormalization phases potentially connected to Asymptotic Safety.
• The thermodynamic and large-scale gravitational regime associated with Emergent Gravity and Fractal Thermodynamics.

This publication follows the methodology previously applied in the study conducted with Queyros Quonde on Fractal Thermodynamics, where a significant convergence was observed through the independent calculation of the fractal coefficient. The current objective is to determine whether a similar convergence can be identified between NTU cosmology and the remaining viable approaches to quantum gravity.

Future work will focus on the mathematical formalization of each transition stage, the derivation of effective field equations through NTU coarse-graining, and the identification of potentially testable predictions that could distinguish the NTU framework from existing cosmological models.
