Toy models of gravitational shielding in the framework of Newtonian theory of gravitation
Bibliographic record
Abstract
In the framework of Newtonian theory of gravitation, three toy models of a hypothetical gravitational shield (GS) are developed. To satisfy the energy conservation law which is violated in the presence of GS, an existence of a special kind of energy (“G-energy”) responsible for shielding and stored in GS is postulated. The models differ from each other by the details of the spatial dependence of the net gravitational acceleration in the presence of GS as well as by the dependence of that acceleration on the amount of G-energy in GS. As an example, the rotation of a dumbbell like object located at the boundary between the regions of space where gravity is affected and not affected by GS is analyzed in details. The motivation to study gravitational shielding, the very existence of which is challenged, is the presence of steadily repeating attempts to observe this phenomenon. No doubt, such attempts will continue in the future. The results obtained in the present paper could be useful in designing such a research.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
