Abstract

fetched live from OpenAlex

We illustrate the thesis that if time did not exist, we would have to create it if space is noncommutative, and extend functions by something like Schrödinger’s equation. We propose that the phenomenon is a somewhat general mechanism within noncommutative geometry for “spontaneous time generation.” We show in detail how this works for the su2 algebra [xi,xj]=2ιλϵijkxk as noncommutative space, by explicitly adjoining the forced time variable. We find the natural induced noncommutative Schrödinger’s equation and show that it has the correct classical limit for a particle of some mass m≠0, which is generated as a second free parameter by the theory. We show that plane waves exist provided ∣p⃗∣<π∕2λ, i.e., we find a Planckian bound on spatial momentum. We also propose dispersion relations ∣∂p0∕∂p⃗∣=∣tan(λ∣p⃗∣)∣∕mλ for the model and explore some elements of the noncommutative geometry. The model is complementary to our previous bicrossproduct one.

Full frame distilled prediction

Teacher imitation

Not 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.
