Wie viel wiegt das Vakuum?
Bibliographic record
Abstract
Zusammenfassung Das Vakuum ist nicht völlig leer, denn die Heisenbergsche Unschärferelation erzwingt Vakuumfluktuationen. Deren Existenz ist über Messungen der Casimir‐Kraft belegt. Folglich muss auch Energie in den Vakuumfluktuationen stecken, die sich nach E = mc2 in Form von Gravitation bemerkbar machen sollte. Nach der Allgemeinen Relativitätstheorie müsste ihre Gravitation die Expansion des Universums beschleunigen. Allerdings wäre die Gravitationswirkung, die sich theoretisch aus der quantenmechanisch ermittelten Grundzustandsenergie des Vakuums ergibt, um etwa 120 Größenordnungen zu groß. Dieser Widerspruch ist eine der grundlegenden, ungeklärten Fragestellungen der Physik. Auf der Suche nach einer Antwort soll das Archimedes‐Experiment als extrem empfindliche Waage die Energiedichte des Vakuums bestimmen. Das Resultat soll Hinweise auf die Ursache des „Problems der kosmologischen Konstante“ liefern.

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.
