MODIFYING GRAVITY IN THE INFRARED BY IMPOSING AN "ULTRASTRONG" EQUIVALENCE PRINCIPLE
Bibliographic record
Abstract
The equivalence principle suggests considering gravity as an infrared phenomenon, whose effects are visible only outside Einstein's free-falling elevator. By curving space–time, general relativity leaves the smallest systems free of classical gravitational effects. However, according to the standard semiclassical treatment, indirect effects of gravity can be experienced inside the elevator through the well-known mechanism of quantum particle production. Here we try a different path than the one historically followed: rather than imposing field quantization on top of a curved manifold, we attempt to upgrade the equivalence principle and extend it to the quantum phenomena. Therefore, we consider, and try to realize in a theoretical framework, a stronger version of the equivalence principle, in which all the effects of gravity are definitely banned from the elevator and confined to the infrared. For this purpose, we introduce infrared modified commutation relations for the global field operators (Fourier modes) that allow us to reabsorb the time-dependent quadratic divergence of the vacuum expectation value of the stress–energy tensor. The proposed modification is effective on length scales comparable to the inverse curvature and, therefore, does not add any dimensional parameter to the theory.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
