Ives: Science Contrarian review (STEP 2, rewrite after QE round 2 MAJOR)

Reviewer role: judges claims by experimental evidence, not consensus; builds the strongest honest case; examines how claims were rejected; applies the same rigour to the inventor. Tags: [read] = from a document in the project (deep reads, _text, digests, QE's quoted lines, and the Moray text I read myself); [calc] = arithmetic reported in a deep read or by QE and used here, or my own; [web] = URL given; [memory] = recall with confidence.

Reading base. Claims 1-4 now rest on primary papers read in depth: Ives-Stilwell 1938 and 1941 (Part II), Ives 1937 (JOSA 27:263, 27:310, 27:305), 1938 (28:296), 1939 (29:183), 1945 (Phil. Mag. 36:392), 1947 (Phys. Rev. 72:229), 1948 (JOSA 38:413), 1949 (JOSA 39:757), plus the Pobedonostsev-Parshin and Faraj deep reads, and Ruderfer's appendix in Moray's Sea of Energy, 5th ed., pp.271-274 (I read it in review/Morray-TH/_text). Claim 7 items rest on digests plus QE's quoted lines and are tagged so. Still not obtained: JOSA 42:540 (1952, in copyright, cited by reference), the 1953 JOSA 43 notes, Rev. Sci. Instr. 9:283 (1938), Nature 168:246 (1951), Hazelett and Turner (1979), Jones JOSA 29:337 and Otting (known only through Ives-Stilwell II), Bridgman's 1959 memo and Lalli 2013.

Corrections to earlier documents (for the orchestrator)

1. My own earlier contrarian.md, claim 4: wrong. It said the content of Ives's gravitation theory was "unread", that it was "a velocity-dependent mass with a force law" that "need not pass other tests", and gave "Never properly tested". The primary papers say otherwise. JOSA 29:183 derives exactly the Schwarzschild interval, and JOSA 38:413 gets Mercury's 42.98 arcsec per century with no fitted constant, and states "The force equations are actually implicit in the general relativity solution" [read: deep reads 1939, 1948]. The earlier verdict is withdrawn and replaced below. The same applies to the arbiter's "presumably chosen to reach 43" and the primer section 4.4 (QE round 2 section 7, items 1-2).
2. My earlier claim 1 section b: "I did not check direction" and "Part II not read" are overtaken. Part II is read. Its answer to the 1938 doublet caveat is on Ives and Stilwell's own numbers (claim 1 below). Direction of the centre shift: the QE recheck records it as a red shift of the centre, resolved from page images in round 1 [read: qe.md Round 1 recheck, D4].
3. My earlier claim 1: the Pobedonostsev-Parshin dissent was "abstract only". It is now deep-read from the six pages (numbers in claim 1 below).
4. My earlier claim 3: "Source gap: no primary derivation checked", and "approach but never coincide". Both are overtaken by the 1937, 1945 and 1949 deep reads. The "never coincide" statement is accurate for the formulas, not for the predictions (claims.md claim 3).
5. The rod-clock-quotient term is defined in JOSA 38:879 (1948), not in 1953 (QE round 2 section 7, item 5).
6. Digest errors that a reader of my earlier file might have copied: H-alpha should be H-beta (4861 A) in the 1938 digest; "He" should be H2; the 1941 factor should be (1 - v^2/c^2)^(1/2); the 1942 ripple-tank comparison uses (1 - v^2/c^2) = 0.658, not its square root [read: qe.md section 4].
7. Web checks done this pass (2 of the 6 budgeted; the rest were not needed): (i) Birkhoff's theory. My earlier [memory: medium] belief that it "drew objections, e.g. that it requires matter with sound speed equal to c" is partly checked only. A search returned Weyl's criticisms: no derivation of the equations from a more general principle, a perfect fluid taken as a primitive entity, and no universal energy-momentum conservation law [web: https://arxiv.org/pdf/gr-qc/9912003 and the search listing, summary level]. The sound-speed point was not confirmed and stays [memory: low]. (ii) Photon: Grangier, Roger and Aspect (1986) found anticorrelation of triggered detections at a beam splitter, violating a classical inequality by 13 standard deviations [web: https://courses.physics.illinois.edu/phys513/sp2019/reading/week1/GrangierSinglePhoton1986.pdf, search summary].

Central claims

Claim 1. Moving clocks run slow: the Ives-Stilwell experiment measured the second-order Doppler shift.

a. Mathematics. Consistent. The centre of gravity of the blue- and red-shifted lines is lambda0 (1 - B^2)^(-1/2), about lambda0 (1 + B^2/2); the first-order term cancels. I reproduce the computed column: 0.0475 A for H2+ at 18,350 V and 0.0117 A for H3+ at 6,788 V; QE reproduces 0.1114 A at 43,000 V [calc]. The exponent inconsistency on p.216 versus p.226 is in the printed 1938 paper itself.

b. Consistency with experiment. Part I (1938). Eight Table III points: observed/computed 0.91-1.04, mean 0.96 (a 3-4% deficit; six of eight at or below). Table II: plates 136 and 137, both discharge-north, read 0.036 and 0.052 A, a 36% spread inside one orientation; so "no orientation effect" holds only at the 10-15% level, which matches Mandelberg and Witten's later 10-15% real uncertainty [read: page image JOSA 28 p.224; calc]. The authors' caveat: every shift was below the 0.09 A doublet separation, so an intensity shift between the doublet components could fake part of it.

Part II (1941), now read. It answers that caveat on the authors' own terms. - The tube ran to about 43,000 V; the H2 shift reached "over 0.11 A as against the previous maximum of 0.047 A". Observed 0.113 and 0.1145 A at 42,260 and 42,280 V against 0.1098 and 0.1073 A computed. That is about 1.2 times the implied doublet separation, so intensity transfer between the components cannot by itself produce it. The paper does not spell out that inference [read: deep read, Table I from page image]. - Limits, which I state with equal weight. The new points are on coarser, faster plates. Nine H2 points sit on average about 3% above the computed curve, the opposite sign to the 1938 deficit, which the authors attribute to a mirror under 100% reflecting. One H3O table entry (0.0012) looks misprinted. The doublet intensity ratio was not measured directly. - Jones's 1939 objection (energy imparted to the "stationary" particles could shift the reference line). Ives and Stilwell found a central-line displacement corresponding to about 750 m/s at 14,000 V with the mirror covered, none within error with it in. A double-ended tube, optics reversed, gave 0.0744 A against 0.0717 A computed at 28,300 V (one point, no error bar), which they say "completely disposes of" Otting's criticism [read: deep read]. This is the authors answering their own critics, with one point and no error budget; it is evidence, and the weight is the reader's.

c. Tested, replicated? Yes, and it is the best-supported claim in the file: Otting 1939; Mandelberg and Witten 1962 (exponent 0.498 +/- 0.025, second hand via Giuliani); Olin 1973; Hasselkamp 1979; laser-era tests; Reinhardt 2007 (Li-7+ at 3.0% and 6.4% of c) [web: https://link.springer.com/article/10.1038/nphys778, abstract level]; Botermann 2014 (Li+ at beta = 0.338, frequencies to < 4e-9) [web: https://arxiv.org/pdf/1409.7951]. One dissent on record, now read. Pobedonostsev and Parshin (Khlopin Radium Institute; SPIE 1989 paper) found the second-order shift 40-82% smaller than special relativity at 150-300 keV and within about 10% at MeV energies. The deep read found no systematic-error budget, separate optical arms, and a classical model of their own that does not explain the deficit [read: deep read]. Faraj (an emission-theory advocate) says the data show only a longitudinal asymmetry; the attribution is not Ives's and the supporting algebra is invalid [read: deep read]. These stay in the record. A reported anomaly with a thin error analysis, at energies where storage-ring tests now reach 1e-9, is not enough to move the verdict; I say the anomaly was never independently repeated in anything I have, and that nobody I can find has gone back to it, which is a gap, not a refutation.

d. If true, what changes? Nothing. It is the mainstream prediction.

Rejection record. Not rejected; absorbed. Einstein's reaction was favourable (NYT 27 Apr 1938, "the most direct proof yet") [web: https://www.nytimes.com/1938/04/27/archives/einstein-hails-proof-dr-ives-provides-best-support-for-relativity.html]. Ives's own account of a hostile Princeton reception (letter 24 Oct 1950, via Hazelett and Turner, one published source, Ives a party; no second source found yet) is about his interpretation. The experiment was Bell-funded and appeared in JOSA, of which Ives was a past president. I find no evidence of blocked funding or publication.

Verdict: Established (the second-order Doppler factor; about 10-15% in 1938, better than 1e-7 now). The Part II extension strengthens it. The Pobedonostsev-Parshin dissent stays on file as an unreplicated anomaly with no error budget.

Claim 2. The result shows a real slowing in a fixed ether; Larmor-Lorentz over Einstein.

a. Mathematics. Internally consistent as a discrimination among contraction hypotheses. With Michelson-Morley and Kennedy-Thorndike, Ives-Stilwell fixes the Robertson-form function; Ives's 1937 papers JOSA 27:177 and 27:389 show Kennedy-Thorndike "cannot by itself test the Larmor-Lorentz hypothesis" and propose the canal-ray experiment to fix the exponent [read: digest; qe.md]. The step to "so there is an ether" is an addition; the same equations are Lorentz's with or without a preferred frame.

b. Experiment. All sides compute the same factor (Jones 1939; Robertson 1956). The experiment contains no ether-drift measurement. Ives's own concessions: the ether's "elusiveness by any measurements of the sort we have been considering" (1937); aberration evidence "not metric". In 1945 he calls aberration, Sagnac and Michelson-Gale "direct proofs" of motion relative to the light-transmitting medium; special relativity predicts these too. New in the record: his 1947 historical note says the clock-rate test is most conclusive because Michelson-Morley can be explained by an entrained ether and mass variation by charge variation, and credits only Einstein with having "believed the equations' predictions" and named the canal-ray shift an experimentum crucis [read: qe.md section 3.11, _text lines 212-307]. That is generous to Einstein and I record it as such. Part II's six pages use neither "ether" nor "relativity"; they credit Larmor and Lorentz.

c. Tested? The strong form (an effect that special relativity does not predict) has never been shown, and the structure rules it out: the ether is undetectable by construction. Not dismissed without testing; not testable by these means. Contemporary evidence that both camps claimed the result: Einstein's remark, and Bell Laboratories Record 1947 (employer, interested party): "first direct proof of the system of compensation for motion embodied in the theories of Larmor, Lorentz and Einstein". Preikschat's Mossbauer rotor thesis (limit 2.0 +/- 5.2 cm/s; the word "Ives" occurs 8 times, not 27) and Ruderfer's 1960 proposal are the neo-Lorentzian experiments; both predict a null at first order in either theory.

d. If true. A physical but undetectable preferred frame would be added to special relativity; no observable changes. On the clock paradox he held (1937; Nature 168:246, 1951, not read) that the ether frame tells which clock lags; the standard resolution (the travelling clock changes inertial frame) is not discussed in the 1937 pages [read: claims.md claim 2].

Strongest honest case for Ives. (i) He ran the experiment Einstein proposed in 1907 and it came out positive. (ii) He correctly said it disfavours entrained-ether and ballistic theories, a live issue in 1938. (iii) Robertson, his referee and critic, wrote that the deductions were "in each case ... valid" and the theory "completely equivalent in substance". (iv) Bridgman used his arguments in 1962. Against: (a) "more decisive evidence for Larmor-Lorentz" outruns the data given his own equivalence; (b) real-but-undeterminable absolute simultaneity is what Bridgman called "a complete negation of the operational attitude" (via Lalli 2014); (c) the strong claim is unfalsifiable as framed. Stake note: Robertson wrote the relativity assessment in the NAS memoir; he is an expert and also Ives's referee and critic. His 1947 referee report on the Birkhoff paper called the "Lorentzian" framing "a bit (ca. 40 yrs) out of date" and the paper was published [web: https://pmc.ncbi.nlm.nih.gov/articles/PMC4856100/].

Verdict (split). Weak form (disfavours entrained-ether and ballistic theories; selects the l = 1 contraction): Established. Strong form (evidence for an ether over special relativity): Not testable as stated.

Claim 3. Ives's alternative theory can be built from classical ether physics and is special relativity under different clock-setting conventions.

a. Mathematics. Now checked on three routes.

• 1937 transported rods and clocks. From ether, contractions and transport-synchronised clocks, Ives gets expressions that depend on the observed transport speeds, reduce to Lorentz's as those go to zero, and for finite speeds agree with special relativity for the same procedure (a 40-digit check; difference first order in transport speed, about 1.7 ps over 1 km at 300 m/s) [read: claims.md claim 3a]. Misprints in eqs. 14, 25, 33, 34, 38-40 do not alter conclusions.
• 1943-45 conservation-law route. No special-relativity formula is put in by hand; but three premises do work the conservation laws alone do not: the inertia of energy (m = E/c^2 for radiation; the 1900 Poincare/Maxwell route, [memory: high] that it predates 1905); an unexplained step that an extra term "must drop out", equivalent to the relativity principle for that process; and clock universality and isotropy, equivalent to Michelson-Morley and Kennedy-Thorndike [read: 1945 deep read]. So "Special Principle of Relativity a superfluous hypothesis" is stronger than the derivation: it moves the relativity principle into the premises rather than removing it. This answers QE's hidden-assumption question for me: not circular, but not assumption-free.
• 1949 inconsistency charge. Ives says the SR derivation "leads to an internal inconsistency if clocks are admitted for distant time setting". His eqs. (19)-(20) are term for term the Lorentz transformation written with clock readings lagging Einstein time by k r' (SymPy, deep read). SR predicts exactly his one-way result c/(1 - ck) for a clock carried at speed q, about c + q/2, tending to c as q goes to 0. The size: a clock walked at 1 m/s over 10 m gives 5.6e-17 s offset and a 1.7e-9 fractional change in one-way speed [calc, deep read]. He knows the limit and rejects it because q = 0 "could not be performed". What survives is the conventionality of one-way simultaneity, a recognised point in the mainstream literature.

b. Experiment. No experiment separates the theories and Ives names none: his 1950 and 1951 papers cite only Michelson-Morley and Ives-Stilwell, which special relativity predicts identically [read: 1949 deep read]. Arthur Miller (1980): "never developed to the point where it could be seriously considered as an alternative". His statement that Einstein's "c firmly established by experiment" was invalid because only out-and-back speeds were measured is correct as logic about one-way speed, and the point is conceded in modern test-theory work [memory: high]; it changes the explanation, not the prediction.

c. Tested? There is no test because there is no differing prediction. This is neither "tested and failed" nor "dismissed without testing". It is a derivation that reproduces a theory's equations, and the reproduction was checked (Robertson 1956; the 1937 and 1949 deep reads).

d. If true. Special relativity's postulates would be derivable from an ether plus conservation laws; nothing measured changes.

Verdict (split). Ives's alternative theory as an equivalent re-derivation: Not testable as stated (an interpretation with no measurable difference). The 1949 charge that special relativity is "internally inconsistent" when clocks are admitted: Refuted by calculation (his equations are the Lorentz transformation with lagged readings; the one-way result is predicted by SR). The conservation-law claim that the relativity principle is superfluous: Not testable as stated, with the hidden premises named above. The earlier "never coincide" reading: accurate for formulas, not for predictions.

Claim 4. Gravitation: the Schwarzschild solution as forces in an ether (JOSA 29:183, Phys. Rev. 72:229, JOSA 38:413).

a. Mathematics. Consistent, checked in deep reads and by calculation. - 1939. From three assumptions (a stationary interferometer in a field behaves like one moving at the speed gained falling from infinity, V^2 = 2GM/R; a null adjustment is preserved; Fitzgerald contraction relative to the local light speed) Ives derives ds^2 = c^2 y dT^2 - R^2 dtheta^2 - dR^2/y, y = 1 - 2GM/(Rc^2). That is the exact Schwarzschild line element, not a 1/c^2 approximation. Every equation checked by SymPy. At the Sun's surface the escape speed is 617.8 km/s and 2GM/(Rc^2) = 4.25e-6 [calc]. He says "There is no experimental information on the behavior of interferometers in gravitational fields" and the subject "can only be treated by making assumptions". - Light bending. Stated in words only, no number. His light-speed field gives the full GR limb deflection 1.75 arcsec (0.88 arcsec, the "half" value, if radial contraction is dropped) [calc]. An isotropic-light-speed ether gives no star displacement and is rejected as "in conflict with observation". - 1947. Birkhoff's equations rewritten in ordinary time and force contain a transverse force v^2/c^2 times the normal part of gravity. This is a re-expression, not a new force: Ives did not endorse Birkhoff as physics ("an independent physical derivation of these transverse forces would be welcome") [read: 1947 deep read]. - 1948. One postulate gives the force equations. Orbit equation to order 1/c^2: d^2u/dtheta^2 + u(1 - 6 G^2M^2b^2/(c^2h^2)) = K-bar, so the perihelion advances 6 pi GM/(c^2 a(1 - e^2)) per orbit, 42.98 arcsec per century for Mercury; Sommerfeld's special-relativistic mass increase under a fixed Newtonian force gives 7.16, one sixth [calc, deep read]. Venus 8.62 and Earth 3.84 arcsec per century on the same formula. - Where Ives overreaches (same rigour for the inventor). (1) His "note added in proof" says the relations are "also exact". The deep read reproduces the angular-momentum law exactly but not his radial equation (23); it differs from the exact Schwarzschild radial equation by terms that give no perihelion advance (for circular Mercury-type orbits a relative difference of about 2.5 parts in 10^8, absorbed into the fitted GM). So (23) is first-order, and the claim of exactness is not demonstrated [calc, deep read]. (2) Two steps are his own choices: F_theta = 0, and splitting the transverse force into a pair by analogy with Birkhoff. His last footnote concedes there is "no ground for favoring (22) and (23) over the simple and symmetrical equations (12) and (13)", which are Birkhoff's. (3) The "one sixth" comparison depends on reading Newton's force as fixed while the mass grows. If the force also scales with the moving mass, the same integration gives one third, not one sixth [calc, deep read]. The comparison is real in McCrea/Sommerfeld's treatment but is not the only special-relativistic reading. (4) The postulate is chosen after Eddington (1917, 1923) and Phillips (1922) had already given the same relations; Ives cites them, and says his solution "is not restricted to this postulate" and is "an alternative solution". It is a re-derivation, not a prediction made in advance.

b. Consistency with experiment. Because it is GR's exact metric for one static central mass, it matches what GR matches for that case: Mercury's perihelion (accepted 43 arcsec per century), solar light deflection (1.75 arcsec, from his light-speed field), gravitational redshift (Pound-Rebka and later; [memory: high]). Shapiro delay follows from the same light-speed field; he never states it (it was measured later, [memory: high]). Binary pulsars and gravitational waves lie outside what Ives treated (one static central mass, no radiation). Ruderfer's sentence "any Lorentz-ether theory of gravitation which provides the static Newtonian gravitational force is necessarily equivalent observationally to general relativity" [read: Moray 5th ed. p.273] therefore overreaches as stated: it holds for the static one-body field Ives derived. For two radiating bodies, a Newtonian force with finite-speed corrections is not shown by anything in the folder to reproduce GR's orbital decay (the binary pulsar decay matches GR to a small fraction of a per cent, [memory: high], not checked here). That is my reasoning, not Ives's; Ives limits his own results ("of purely optical significance"; "no non-Euclidean geometry, nor new law of gravitation") and does not claim it.

c. Tested? Ives's formulas are tested wherever the Schwarzschild metric is tested, because they are the same formulas. The one place his framework is explicitly open is the large interferometer: the 1939 paper says that if null invariance fails for large interferometers, "a sufficiently large and sensitive interferometer could be used to detect motion in a gravitational field". In the 1939 chronotopic-interval paper (JOSA 29:294, digest) he tabulates combinations of contraction and clock rate that all give null results and says choosing among them needs experiments "where the gravitational parameter varies", such as near the Sun [read: qe.md section 3.3]. No such interferometer experiment is on record in the folder. Ives expects invariance to hold, so he is not predicting a difference; he states where his framework is underdetermined.

How it was received. Robertson's referee report on the 1947 paper called the "Lorentzian" framing "a bit (ca. 40 yrs) out of date" and the paper was published. I find no review of the gravitation papers in the sources, favourable or not. Ruderfer (1975): "The continued neglect of Ives' gravitational theory is unwarranted in view of current interest in comparative evaluation of all viable theories" [read: Moray p.273, note 9; he cites C. M. Will, Sci. Am. 1974, which I did not read]. Strongest case for that view: the derivation is short, uses only equivalence-type postulates, and recovers the standard results with transparent assumptions, which is useful to a learner and to test-theory work. Strongest case against: since it adds no prediction and the author says so, there was nothing to test or cite. That is neglect by irrelevance, not by suppression. Nothing in the record suggests it was blocked: it appeared in Phys. Rev. and JOSA.

d. If true. The question changes. If Ives's papers are correct, what changes is the reading of the formalism: GR's metric is reproducible as forces in flat space with absolute time and a preferred frame; the claim by GR that "force" is negated becomes interpretive. Observed physics does not change (Ives, 1948: the force equations "are actually implicit in the general relativity solution", which "is commonly claimed to negate the concept of force").

Verdict (split). (i) The numerical predictions (Mercury 43 arcsec per century, light bending 1.75 arcsec, redshift) for a single central mass: Established, as GR's results, which Ives's derivation reproduces. (ii) Ives's claim that this is a different, ether-based and force-based explanation: Not testable as stated (no measurable difference; Ives concedes it). (iii) His preference for his force pair over Birkhoff's: Not testable as stated. His own footnote 9 says so. (iv) A large interferometer in a gravitational field: Never properly tested (not dismissed; no experiment on record). (v) Exactness of the 1948 force equations ("also exact"): Never properly tested by Ives; the deep read finds only first-order agreement, so this is a gap in his proof. (vi) The earlier belief that the theory was fitted to 43 arcsec: Refuted by calculation (no constant is adjustable; deep reads 1939, 1948). Replaces the earlier "Never properly tested".

Claim 5. Einstein did not derive E = mc^2 in 1905.

a. Mathematics. My earlier analysis stands. Ives's chain shows (H0 - E0) - (H1 - E1) = L[(1 - v^2/c^2)^(-1/2) - 1] and K0 - K1 = (m - m')c^2 [same bracket], giving a ratio equal to 1 only by assumption. Ohanian, agreeing with Stachel and Torretti, says this does not make Einstein's argument circular. In my reading Ives imposes the particle kinetic-energy formula Einstein deliberately avoided. Ives's source is Planck's 1907 first-approximation objection, which Ohanian calls "perfectly correct" [read: Ohanian p.5]. Ives accepts E = mc^2 and credits Poincare 1900 and 1904 [read: 1952 abstract, per research/files]. In 1953 he retreats: "No implication ... was intended" and "something must be added ... from valid physical considerations, not by assumption". Ohanian's citation "Am. J. Phys. 42, 540" is his slip for JOSA 42(8):540.

b-c. E = mc^2 is established and not disputed by anyone here. Not an experimental question. Jammer (1961), Arzelies (1966) and A. I. Miller (1981) supported Ives; Stachel and Torretti (1982) answered; Ohanian (2008) agrees on a different flaw.

d. Nothing in physics; the history of derivations. New in the file: Ives's own 1942-45 derivations use m = E/c^2 for radiation as input (see claim 3); this is a Poincare/Maxwell-era input.

Verdict (split). "Circular" as Ives set it up: Internally inconsistent (he assumes the formula Einstein avoided). "Einstein's 1905 argument is not a general derivation": Established as history (Planck 1907; Ohanian 2008). E = mc^2 itself: Established.

Claim 6. Atoms are not clocks (Bonizzoni-Giuliani, Giuliani; not Ives's claim).

The Schroedinger-1922 photon-recoil treatment gives the same factor as the wave Doppler formula; the recoil correction is about 1e-9 for H-beta [calc, memory high]. Distinguishing the two readings needs more precision than 1938 data (or Part II's coarser plates) give. Optical-clock experiments (Chou 2010, per Giuliani) treat a trapped ion as a clock directly, weakening "atoms are not clocks" as a general rule.

Verdict: Not testable as stated (an interpretation with no measurable difference at available precision).

Claim 7. Ives's separate physical claims (not only a different explanation).

For each item I say whether it is a different prediction or a different explanation, what depth I read, and what happened to it.

(a) The photon will be abandoned (1951 Rumford lecture). A different prediction. "I venture to predict that this will be done, and that the photon will go the way of the 'caloric' that Rumford demolished." Basis: standing waves (a photon would have to exist and not exist alternately in loops and nodes), Lorentz's 1910 coherence objection, Poincare's "vestibule" (the quantum is in the atom, not the radiation), wave mechanics placing h in the atom, and Beck and Sommerfeld bipartition-angle data said to favour waves. He concedes "the difficulty of arriving at an explanation of all optical phenomena, such for instance as the Compton effect" [read: _text 1951, lines 2165-2191 via QE; digest]. Read from digest plus QE's quotations. - Experiment. Grangier, Roger and Aspect (1986): anticorrelation at a beam splitter, violating a classical inequality by 13 standard deviations, in agreement with single-photon states and in contradiction with any classical wave model [web: https://courses.physics.illinois.edu/phys513/sp2019/reading/week1/GrangierSinglePhoton1986.pdf]. Single-photon sources and photon antibunching are standard [memory: high]. - Strongest honest case for Ives. In 1951 it was a real position held by serious physicists. The photoelectric threshold and standing-wave results he cites can be reproduced by a semiclassical treatment (atom quantised, field classical) [memory: high; Lamb-Scully 1969 is the usual citation, not checked here]. His own standing-wave work is mainstream and uncontested. His caution (the Compton concession) is honest. Against: the prediction was made as a prediction, and it failed: photon counting and antibunching experiments, which he could not have known, rule out a classical field for these light states. - Verdict: Tested, not supported. The wider semiclassical point about the photoelectric effect is Historically superseded but instructive. Kept in the record whatever the verdict.

(b) Radiation pressure on a moving absorber (JOSA 32:32, 1942). A different prediction: earlier published results (Lorentz P = E_i; Poynting-Abraham P = E_i(1 + v/c)) are wrong, and the pressure on an absorber moving toward the source is E_a(c + v)/(c - v) [read: digest; QE section 3.8]. I have not checked this against a textbook calculation, and the digest does not define E_a against E_i; the answer depends on that definition. The 1945 paper takes the pressure on a moving reflector, 2E(c - f)/(c + f), from Richtmyer's textbook [read: 1945 deep read], so he treated the textbook result as acceptable there. Verdict: Never properly tested (a calculation, not an experiment, would settle it; I did not do it, and the Mathematician should).

(c) A rotating disk "dishes" (JOSA 29:472, 1939). A different prediction, in a narrow sense: the Wood-Hackett "twist" follows from Fitzgerald contraction, and the disk takes a saw-blade shape, paraboloidal at small angular velocity [read: _text lines 197, 234-242 via QE]. No experiment on record. Whether it differs from special relativity with real elastic stresses is not settled in the documents. Verdict: Never properly tested.

(d) Ripple-tank analogues with Stilwell (JOSA 31:14, 1941; 32:25, 1942). A demonstration, not a test of light. Capillary waves on mercury, medium moving at v/c = 0.585 (11.28 cm/s against 19.20 cm/s), reproduce the stationary interference pattern when lengths are scaled by the Fitzgerald factor and periods by the Larmor-Lorentz factor; Fresnel drag and aberration also appear. One measured ratio, 0.852, disagrees with the ideal (1 - v^2/c^2) = 0.658; the authors attribute the difference to capillary-wave dispersion [read: _text lines 38-41, 216-218 via QE; calc 1 - 0.585^2 = 0.658]. I note that this attribution is untested, and that a 30% miss on a headline number deserves more than a one-line explanation. Verdict: Established as a classical-medium analogue (a lab result about water waves); it does not test the ether for light. The clearest physical picture in the record of what a Lorentz ether means.

(e) Velocity and rod-clock-quotient statements (1948-51). A different explanation, not a different prediction (claim 3).

(f) Large-interferometer door (1939, 1948). Claim 4(iv).

(g) Aberration as the "strongest evidence" for the ether (1937, JOSA 27:263 p.10). Evidence by "sheer weight of enormous probability", not a measurement separating ether from special relativity, which also predicts aberration. Verdict: Not testable as stated.

The owner's questions: why Ives matters to Moray, and whether a Lorentz ether adds forces

Why Ives matters to Moray (what the documents establish). No Ives paper mentions Moray. The link is Ruderfer's appendix "Neutrino Structure of the Ether" (Lett. Nuovo Cimento 13:1, 1975, reprinted in Moray's The Sea of Energy, 5th ed., pp.271-274) [read: Moray text I read]. His argument: 1. The widespread rejection of an ether "applies to a Galilean ether, but not to a Lorentz-invariant ether since its description of observation is necessarily identical to that of relativity". 2. "The most direct verification of the validity of a Lorentz ether, and one which is independent of relativity, is found in the theoretical works of IVES": the classical derivation of the Lorentz transformations (Phil. Mag. 1945), the consistency with experiment (JOSA papers 1937-52), and "a classical derivation of the Schwarzschild metric, hence ... an identical explanation of the three famous tests of relativity". 3. Then: "The admissibility of the Lorentz ether focuses attention on its properties." The ether "is not directly observable by any known dynamic or electrodynamic means yet it is associated with the physical attributes of matter-free space, i.e. the vacuum, and therefore has observable energy properties", citing the Lamb shift and anomalous gyromagnetic ratios. Ruderfer defines the ether as "the totality of all the presently unobservable forms of energy that may exist in the microcosm", proposes a sea of low-energy neutrinos, and says "the total unobservable energy in the neutrino sea may far exceed the total energy contained in matter, i.e. the vacuum is then a plenum rather than a void".

Moray's "sea of energy" is a separate and earlier idea. What Ives gives Ruderfer, and through him Moray's book, is respectability for a physical ether: a documented, published, experimentally consistent Lorentz-ether theory by an accomplished experimenter (past president of the Optical Society; Bell Labs; NAS member). The energy content is Ruderfer's addition; none of Ives's 31 papers digested assigns the ether an energy content that could be tapped, and the deep reads of 1939, 1945 and 1948 state the ether supplies a frame and a mechanism, not a field, force or energy source [read: qe.md section 9; deep reads]. Ruderfer is an interested party: he advocates the neutrino-sea ether and cites Ives as support. Whether a low-energy neutrino sea exists with energy exceeding that of matter is a separate claim for the Physicist; I did not weigh it, and the Ives papers neither support nor refute it. Ives's standing-wave photoelectric work (1924-1951) is mainstream and bears on Moray's interests in standing waves and photoelectric conversion, but no paper gives an energy-conversion efficiency.

"Even if Ives is right, the aether follows Lorentz and Einstein; so it only changes the explanation." This reading is correct for the core theory, in the authors' own words. Robertson: "completely equivalent in substance to the special theory of relativity". Ives 1937: the ether's "elusiveness by any measurements of the sort we have been considering". Ives 1939: "no ... new law of gravitation". Ives 1948: the force equations "are actually implicit in the general relativity solution". Ruderfer: "necessarily equivalent observationally". So a Lorentz ether adds no new force and no new prediction to Lorentz and Einstein; it supplies a different story (a physical medium, absolute time, real contractions) for the same measured numbers. Those who prefer the ether reading are choosing on grounds of physical picture, not data. Four qualifications, each a place where "same physics, different words" needs care. - (i) Ives writes forces that GR keeps in geometry: the 1947 transverse force of size v^2/c^2 times the normal part of gravity, and in 1948 a position-dependent mass factor. His 1948 paper says they are the same physics seen two ways. - (ii) Relative to special relativity alone, gravity needs position-dependent mass, clock rate and length, not only speed-dependent ones. That is the content of the one-sixth result. - (iii) Ives's separate physical claims (claim 7) are real predictions: the photon (Tested, not supported), radiation pressure and disk dishing (Never properly tested). - (iv) In one respect the ether is not "only" explanation: Ives claims the one-way speed of light is not c for any real clock-set experiment. That is a statement about operations, and SR agrees (the offset is tiny).

Other pertinent evidence kept in the record (whatever the verdict)

• Hostile-reception account (Ives to Butterfield, 24 Oct 1950; Princeton 1938; Pauli): one published source, Ives a party.
• Library of Congress MSS27508 (15 boxes, about 5,000 items). Butterfield describes anti-Einstein feeling in "certain scientific circles", Einstein "castigated as left-wing radicals". Ives to Butterfield, 5 Oct 1951: championing "the classical English school of physical thought ... against the paradox of the Semitic school"; Lalli reads it as implicitly anti-Semitic ("seems to imply"; discussed in Lalli 2013, not read). Only this one sentence of the letter is quoted. It bears on how Ives argued his case and who his allies were, not on whether his numbers are right.
• Later use by anti-relativity circles: Hazelett and Turner (editor Hazelett had a commercial stake as vice president of Hazelett Strip-Casting per Gardner, a critic; Giuliani calls the preface "grossly anti-relativist", his characterization); Nieper's free-energy book; "Galileo Was Wrong"; the Chinese Academy of Sciences "Relativity Criticism Group". Robertson in 1956 worried the work would be "seized upon"; this evidence shows it was.
• Dirac, "Is there an aether?" (Nature 168:906, 1951): a mainstream physicist reopening the question, answered by Ives (1953). US Naval Research Laboratory bibliography (Benton, 1959) lists Ives-Stilwell as verification of clock retardation.
• Funding and publication: Bell-financed; no sign of blocked publication. Ruderfer's note 9 and Robertson's "40 years out of date" are the only recorded evaluations of the gravitation papers.
