Epistemic note
This project constitutes a deductive structure based on constraints and invariants,
not a philosophical hypothesis nor a physical theory.
Its contents are not evaluable in isolation:
each individual page presupposes the full conceptual structure of the site.
Any judgment formulated without examination of the complete context
is necessarily partial and non-conclusive.
The distinction between structural deduction and interpretation
is an integral part of the model.
The problem of quantum gravity arises from the coexistence of two highly effective theoretical frameworks: General Relativity and Quantum Mechanics. Both are internally consistent and extensively supported by experimental evidence, yet they resist unification within a single formalism.
Current research explores many directions (string theory, loop quantum gravity, emergent spacetime, holography), but there is no shared criterion that clearly distinguishes, at a conceptual level, admissible paths from non-admissible ones.
Within the framework of the Sfera del Tutto, this difficulty is interpreted primarily as a regime mismatch, rather than as a lack of mathematical tools. General Relativity operates in a regime of low operational conflict (order, continuity, temporal stability), while quantum field theory explores regimes of high operational conflict (fluctuations, discreteness, instability of time).
Forcing both regimes into a single descriptive layer may therefore be structurally inappropriate. The stress test consists in verifying whether the central rules (conservation, continuity, coherence, invariance) remain valid across the transition between these regimes.
Stress test. Applying the central rules to the quantum gravity problem reveals explicit conceptual constraints.
Conservation. Any approach that implies destruction of information in singularities or fundamental processes requires a violation of conservation and is therefore not admissible.
Continuity. Models that introduce ontological jumps between physical regimes (or non-mediable transitions between descriptions) break the continuity required by the center and are not compatible.
Invariance of the rules. Theories in which fundamental laws depend on scale, energy, or regime require different rules at the center and fail the invariance test.
Outcome. The stress test does not select a theory of quantum gravity, but restricts the space of coherent directions, excluding those that require violations of the central rules of the Sfera del Tutto.
From this perspective, the Sfera del Tutto does not propose a theory of quantum gravity. It does not introduce equations, models, or experimental predictions.
Its role is strictly orientational: to exclude approaches that require violations of the central rules (such as information destruction, ontological jumps, or scale-dependent laws), and to identify the type of conceptual transitions that a coherent theory would have to respect.
