Kelvin's Vortex Model of the Aether: Why It Failed, Whether the Reason Transfers, and What Its Mathematics Left Behind

Abstract: The Theory of NeoGravity states a physical cause for gravitation. Space is not an empty void; it is filled, everywhere, by the Ether Plenum. Every body gives off radiation without pause — the Sun, the Earth, a stone in the hand — most of it invisible, across the whole spectrum from radio waves to gamma rays. That radiation carries momentum outward, into the Plenum. The Plenum returns it, inward, on the body that sent it out; Newton’s third law allows nothing else. That returned load is gravity, the Radiative Undertow. It is compressive, so the Plenum settles denser toward a mass, and a body falls by answering to the state of the Plenum where it is. Nothing acts across empty space. In this account the curvature of a four-dimensional spacetime metric describes the Plenum’s settled profile and does not cause it: Newton’s potential, Einstein’s metric and the gravitational field are three names for one state of the Ether Plenum under load. A ring of smoke crosses a room holding its shape while the rest of the smoke thins and is gone. William Thomson, Lord Kelvin, proposed in 1867 that atoms are knotted vortex rings in a frictionless fluid aether, one knot for each element; Helmholtz had proved in 1858 that such a ring can never be made or unmade. The theory failed after two decades, for five reasons that were written down. It had no account of charge, magnetism or light, its knots gave no spectra, it needed a fluid with no friction and no give, a rival explained more, and it was a mechanical medium with definite material properties. Each of the five can be put to the Ether Plenum of the Theory of NeoGravity. Three do not reach it: the Plenum is electromagnetic by definition, makes no claim about atoms, and is compressible, which its derivation rests on. Two reach it and are not yet answered. Any aether account of gravitation stands against general relativity, which has passed every test put to it. And the Plenum must be shown consistent with the Lorentz-invariance bounds, now at about one part in a hundred thousand million million; a preferred frame showing at that level would end the framework. Kelvin's mathematics outlived his atoms: Tait's catalog of knots, begun to count candidate atoms, founded knot theory, and the Kelvin–Helmholtz instability, which shares only his name, still sets the point at which a sheared layer rolls up into breaking waves. Five statements say what the Ether Plenum is. They are set down before any result, in one place, so that nothing can be slipped in afterwards to rescue a number that comes out wrong; that is their purpose, and the reader is entitled to hold the theory to it. The first two say nothing that is not already true of water, or of steel, or of air. The Plenum is neither created nor destroyed; and when it is pushed, it moves. Any physicist would grant those two of any material at all, and they cost the theory nothing. It is the three that follow that commit it. Squeeze the Plenum and it presses back, with exactly one third of the energy it holds; and that fraction is not chosen but forced, because whatever fills it has no mass. Twist it and it answers as a fluid does that remembers, for a moment, having been a solid: stiff against a quick disturbance, yielding to a slow one. And a body holds the Plenum about it denser than it is far away, by an amount fixed by the body’s mass; matter and Plenum trade momentum through that and through nothing else. This, then, is all the theory asks of its reader: five statements about the Ether Plenum, and no more. Everything else in the forty papers is drawn from those five, and where a step remains to be taken, the paper names it. Where the theory agrees with Newton and with Einstein it says so, and in the weak field, where nearly all the testing has been done, it cannot be told apart from either. Where it differs from them it names the measurement that would settle the matter, and where a proposal of its own has failed, the failure is kept in print beside the results, with the arithmetic that undid it. The theory is new, and it is the work of one independent researcher; these forty papers are its case, made as fully as the evidence allows.
