The Uneven Death of the Ether: Functional Unbundling and the Fate of a Scientific Object
Year: 2026
Type: preprint
Abstract: The ether did not disappear from physics in a single experimental or conceptual event. It had carried a bundle of tasks: filling space, securing contact action, supporting waves, defining rest, storing energy and momentum, and giving physical structure to space. This article reconstructs the ether’s decline by tracking those tasks rather than treating the ether as one enduring object. It applies a need-bearer-function-fate matrix from plenism and wave optics through Maxwell, Lorentz, Einstein, quantum vacuum discourse, and Einstein-aether theory. The reconstruction shows three distinct outcomes: elimination of a function, transfer of a function to fields or spacetime geometry, and persistence of an explanatory need under a new formulation. This functional continuity neither identifies modern fields with historical ethers nor establishes a realist lineage. It explains instead why the ether could die unevenly: its mechanical carrier and privileged frame were rejected while several of its former jobs survived elsewhere.
