Working Backward Through the Maze: A Reverse Derivation of the NeoGravity Ether Plenum From Observation, Using Newtonian Relativity Mathematics Alone
Year: 2026
Type: preprint
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. Beginning from the observations and asking what structure the Plenum needs for them to follow, rather than searching from the postulates for a formalism that reaches them, the answer is a single separable first-order differential equation. The missing ingredient is neither exotic nor new: classical hydrostatic equilibrium, the same principle governing a planetary atmosphere. A fluid takes its structure not from the local force but from the state it settles into under it, and because equilibrium integrates the force rather than reproducing it, an inverse-square load produces a profile exponential in the reciprocal radius. The equation-of-state parameter is then not free: the Plenum is electromagnetic, its quanta are massless, the stress-energy tensor is traceless, and the equation of state is forced to that of a radiation field. Matching the coefficient the measured solar deflection requires fixes the one remaining exponent and determines the Plenum completely. The result is one expression for the refractive index of space near a mass, with no free parameter beyond the calibrated constant. From it come a deflection of 1.7512 arcseconds, a Shapiro delay of 232.6 microseconds, a redshift of 2.459 × 10⁻¹⁵, and Mercury's perihelion advance of 42.98 arcseconds per century. Because the expression is exact rather than approximate it keeps going past those four, predicting a second-order coefficient of 2.00 against general relativity's 1.75, worth 0.73 microarcseconds at the solar limb. 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.
