Casimir Force, Boundaries, and the Structure of the Physical Vacuum

The precision measurement of the Casimir force performed by U. Mohideen and Anushree Roy in 1998 constitutes one of the historically important experimental demonstrations that submicrometer interactions between conducting bodies can be quantitatively described only when geometry, electromagnetic properties, surface structure, and sepa- ration are appropriately taken into account. Using an atomic force microscope, Mohideen and Roy measured the attraction between a metallized sphere of approximately 196 µm in diameter and a flat plate over surface separations ranging from approximately 0.1 to 0.9 µm. Their experimental results agreed with theoretical calculations incorporat- ing finite-conductivity, surface-roughness, and thermal corrections, with a reported root-mean-square deviation of approximately 1.6 pN between theory and experiment (Mohideen and Roy 1998). This article develops a critical–propositional examination of that experiment in dialogue with the Theory of Objectivity (TO) formulated by Vidamor Cabannas and Denivaldo Silva. The analysis is governed by an explicit methodological distinction between modal necessity, empirical compatibility, indirect corroboration, and theory- specific confirmation. Within TO, the Absolute Truths are treated as modal premises rather than hypotheses whose logical necessity is created by experimental measurement. Empirical results may nevertheless establish operational bridges, expose tensions, or constrain proposed physical interpretations of those premises. Particular attention is given to the First Absolute Truth, according to which before the emergence of the universe there was Nothing, although this Nothing is not absolute non-being but an eternal logical and mathematical essence; the Second Absolute Truth, according to which each existing element possesses its own unique magnetic field that individualizes it; and the Fifth Absolute Truth, according to which an element requires relational observation or placement within the frequency domain of at least two other elements for logical existence, where observation is physical and relational rather than human or conscious. The Casimir experiment is found to have its strongest dialogue with the TO concepts of boundary, interface, relational dependence, and phenomenic emergence. It also offers an indirect empirical bridge to the TO distinction between physical emptiness and absolute Nothingness, because the experimentally relevant region between the bodies cannot be treated as simple ontological non-being. Yet the experiment does not demonstrate the primordial Nothing of TO, does not establish a unique individualized magnetic field for every element, does not experimentally prove the relational criterion of the Fifth Absolute Truth, and does not demonstrate the TO identification of information produced in atomic relations with atomic radiation. The article argues that the scientific importance of the Mohideen–Roy experiment for TO lies not in treating the Casimir force as a proof of the entire theory but in using it as a disciplined operational bridge from modal ontology to measurable boundary- dependent phenomena. A program of genuinely discriminating TO experiments is therefore proposed in which TO must derive quantitative deviations, additional variables, or novel information–radiation signatures not already entailed by conventional quantum electrodynamics or Lifshitz theory.
