This is Hal Puthoff’s polarizable-vacuum treatment of gravity as it appears in a book rather than a journal — a chapter in the 2002 Springer volume ‘Gravitation and Cosmology: From the Hubble Radius to the Planck Scale’. The argument is the one this library sets out in full on the journal page: do not start with curved spacetime and tensors, start with the vacuum as a polarizable medium whose electrical stiffness varies with position. A single number, the dielectric constant of the vacuum, then carries gravity. Where it rises, light runs slower and bends, clocks run slow, rulers and atoms shrink and effective mass grows, and the interval written in that one number turns out to be the ordinary metric tensor. The chapter version puts its weight on two things: that the picture gives you a physical grip on what a curved metric actually means, and that in strong fields the two formalisms stop agreeing — which is where an experiment could tell them apart.
Why it matters hereChapter 4 is about treating the metric as an engineering variable, and chapter 3 about the field that sets it; this chapter is where Puthoff put that case in front of a gravitation-and-cosmology audience in book form, and it is the version that states the strong-field divergence as an invitation to go and measure.
What it claims
01General relativity can be done a second way. Rather than treating its topics in tensor formulations in curved spacetime, the chapter presents an alternative approach based on treating the vacuum as a polarizable medium.Chapter abstract, first and second sentences
Published and peer-reviewed02The approach earns its place by explaining as well as computing: beyond simply reproducing the standard weak-field predictions of general relativity, the polarizable-vacuum approach provides additional insight into what is meant by a curved metric.Chapter abstract, third sentence
Published and peer-reviewed03One scalar does the work. The polarizability of the vacuum near a mass differs from its far-field value, and that single dielectric constant then fixes the velocity of light as c divided by it, the rate of clocks, the length of rods, the effective mass of matter and the frequency of emitted light.Chapter abstract, second sentence; the mechanism is worked in the author’s preprint at Section II, Equations 3 to 15
Published and peer-reviewed04Where the two pictures have been tested, they agree exactly. Expanded to the order the three classical tests of general relativity require, the polarizable-vacuum metric tensor and the Schwarzschild metric tensor are identical, and the charged case likewise reproduces the Reissner-Nordstrom result.Chapter abstract, third sentence; the identity is worked in the author’s preprint at Sections III D and V B, Equations 41 to 46 and 66 to 71
Published and peer-reviewed05What to watch is the strong-field case, where the two formalisms diverge in their predictions — and the chapter names that divergence as fertile ground for both laboratory and astrophysical tests, which is to say it is a difference someone can go and measure rather than a matter of taste.Chapter abstract, closing sentence

Abstract
Topics in general relativity (GR) are routinely treated in terms of tensor formulations in curved spacetime. An alternative approach is presented here, based on treating the vacuum as a polarizable medium. Beyond simply reproducing the standard weak-field predictions of GR, the polarizable vacuum (PV) approach provides additional insight into what is meant by a curved metric. For the strong field case, a divergence of predictions in the two formalisms (GR vs. PV) provides fertile ground for both laboratory and astrophysical tests.

The way in
https://doi.org/10.1007/0-306-48052-2_44A SHORT COMPANION PAGE — THE FULL SHEET IS ELSEWHERE. This is the book-chapter form of a single body of work that reaches this library three times: the arXiv preprint gr-qc/9909037 at /library/stm-63db72dc94, this chapter, pages 431 to 446 of ‘Gravitation and Cosmology: From the Hubble Radius to the Planck Scale’ published by Springer Netherlands, formerly Kluwer Academic Publishers, in 2002, and the journal version of record, Foundations of Physics volume 32, pages 927 to 943, June 2002, at /library/stm-a6d4e7a40a. The journal page carries the physics in full, with six claims located to the author’s own preprint by section and equation. This page is deliberately short: it records the chapter as its own publication, reproduces the chapter’s own abstract, which is not word for word the journal abstract, and sends the reader to the journal page. LICENCE. Crossref carries no licence statement of any kind for this identifier; Unpaywall and OpenAlex both report it closed with no repository copy. No text of the chapter is reproduced here beyond the author’s own abstract. ABSTRACT SOURCE. The abstract below is Springer’s own deposit for this digital object identifier, recovered through the OpenAIRE record on 2026-09-08 after Crossref, OpenAlex and Semantic Scholar all returned it empty; nothing in its wording is altered. HOW IT DIFFERS FROM THE JOURNAL ABSTRACT. The chapter abstract is the shorter of the two. It drops the naming of Dicke’s model and of the TH-epsilon-mu formalism, and it states the weak-field agreement as something the approach goes ‘beyond’ rather than as a result being reported. Both abstracts close on the same claim: that in the strong-field case the two formalisms diverge, and that the divergence is fertile ground for laboratory and astrophysical tests. WHAT THE CLAIMS BELOW REST ON. The chapter text itself was not reachable. The claims are written from the chapter abstract, and where a claim names a mechanism the abstract only gestures at, the locator says so and points into the author’s own preprint, arXiv gr-qc/9909037 version 2 of 19 February 2001, read in full on 2026-09-08 and carrying the same sectioning.
