The reading
Core claim
The paper replaces the force on a light relativistic particle, F = G M m/r², with F ≈ G M_sun γ m / r²—gravitational 'charge' is energy, not rest mass. The key result, Eq. (18), is the limiting radius r_A-lim = G M_sun / 2 = 6.6 × 10^9 m, where energy scales exactly with γ, so gravitational bending auto-ramps with the energy gained from the Parker electric field. This radius lies outside the 0.70 × 10^9 m solar radius, so protons and heavier nuclei can circle the sun and be accelerated over many turns. The two-stage 'double slingshot' (Jupiter pre-acceleration, then solar capture) lets a substantial fraction of cosmic rays up to 10^6 GeV/nucleon begin life in the solar system. The same chang
What carries the argument
The central object is the revised gravitational force law, Eq. (14): F ≈ G M_sun γ m / r², in which the Lorentz factor γ of a fast light particle enters the gravitational coupling between a heavy body and that particle. Its companion anchor is the limiting capture radius r_A-lim = G M_sun / 2 = 6.6 × 10^9 m (Eq. 18), where the particle's energy scales exactly with γ, so the gravitational bend strength automatically matches the particle's growing stiffness—an 'auto-ramping' property the paper likens to an ideal accelerator bend field. The Parker solar-wind model supplies the longitudinal electric field that adds energy each turn, and the dipole magnetic fields of the sun and Jupiter superpose
Load-bearing premise
The load-bearing premise is the revised gravitational law itself: a fast light particle is pulled toward a heavy body with force proportional to its total energy, γ times its rest mass—whereas under the standard law the capture radius for a relativistic proton is about 1.5 km, far inside the sun, so the proposed solar accelerator cannot work; the author explicitly doubts that the revision can be accommodated by general relativity.
What would settle it
Two concrete checks would settle it. (1) Search heliospheric particle data for the bound, helically orbiting proton population the mechanism requires—long-lived capture orbits between one and ten solar radii with energies ramping over many turns; spacecraft observations instead show a radially outflowing solar wind with no gravitationally bound relativistic component. (2) Measure the gravitational deflection of relativistic particles as a function of Lorentz factor: general relativity predicts deflection nearly independent of γ at leading order, while the revised law predicts deflection propor
If this is right
- If the revised law is right, a substantial fraction of cosmic rays up to at least 10^6 GeV/nucleon can be produced inside the solar system, and the measured flux would be an incoherent mixture of a solar-system class and a non-solar class that current detectors cannot separate by source.
- The revision would leave ordinary astronomy and low-energy physics untouched—slow or heavy bodies have E ≈ m—so all well-understood gravitational processes survive; the effect appears only for relativistic light particles near a massive body.
- Energy-coupling gravity would alter the interpretation of missing mass and dark energy, because the gravitational contribution of relativistic matter would be systematically underestimated in the standard cosmological accounting.
- The proposed E&M storage ring would let two different isotopes co-circulate at different velocities with a fixed, phase-locked crossing pattern, enabling rear-end nuclear collisions in a moving frame—for instance 6Li + 7Li → 13C + γ—with spin control and weak-interaction channels not accessible in fixed-target experiments.
Where Pith is reading between the lines
- My inference: the cleanest discriminator is a γ-dependence test. General relativity predicts gravitational deflection of a relativistic particle that is essentially independent of its Lorentz factor at leading order, while the revised law predicts deflection growing ∝ γ; the author notes that no experiment has ever been motivated to look for such an effect, so a deflection measurement at two parti
- My inference: the paper's ceiling of 10^6 GeV/nucleon (about 1 PeV) sits essentially at the observed 'knee' of the cosmic-ray spectrum. If the solar mechanism is correct, the knee would reflect solar-system acceleration limits—set by the Parker field strength and the roughly 10-year run imposed by the 22-year magnetic cycle—rather than Galactic propagation, a distinction testable through compositi
- My inference: the argument generalizes to every magnetized, windy star, so the double-slingshot efficiency implied by solar-system production could be extrapolated over the galaxy's stellar population to predict a diffuse galactic cosmic-ray budget; comparing that budget with observed fluxes would give an independent check of the claimed efficiency.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The paper argues that replacing masses by total energies in Newton's law, Eq. (14), allows the Sun to capture and accelerate protons to energies of at least 10^6 GeV/nucleon within the solar system. The key quantitative anchor is Eq. (18), r_A-lim = G M_sun/2 = 6.6e9 m, which the paper compares with the solar radius 0.6957e9 m. A "double slingshot" mechanism is then proposed, involving pre-acceleration at Jupiter and capture around the Sun. A large fraction of the manuscript is devoted to accelerator physics: co-circulating E&M storage rings, rear-end nuclear collisions, kinematic tables, and a proposed lattice design for experiments such as 6Li + 7Li -> 13C + gamma.
Significance. If the modified gravitational law were correct, the paper would have broad implications for cosmic-ray origin, missing mass, and dark energy. The storage-ring material contains detailed kinematic tables and design considerations for co-moving beams, which may be of technical interest. However, the central astrophysical claim rests on an unsupported, ad hoc modification of Newtonian gravity and on a capture-radius calculation that is dimensionally inconsistent. The numerical agreement claimed between r_A-lim and r_sun is an artifact of unit mishandling, so the proposed solar cosmic-ray mechanism is not established.
major comments (3)
- [Section 8, Eqs. (17)-(18), and Recapitulation Eqs. (41)-(42)] The quantitative anchor is dimensionally inconsistent. With SI units restored, G M_sun/2 = 6.6e19 m^3/s^2; converting to a length requires division by c^2, giving about 7.4e2 m (0.74 km), not 6.6e9 m. Equivalently, using KE_A = (gamma_A - 1) m_A c^2 in Eq. (17) gives r_A-lim = (G M_sun / 2c^2) gamma_A/(gamma_A - 1), which approaches 0.74 km for gamma_A >> 1. This is five orders of magnitude smaller than the solar radius, not ten times larger. The claimed capture orbits outside the Sun and the 'double slingshot' mechanism therefore do not follow from Eq. (18).
- [Section 8, Eq. (14)] The modified gravitational force law F = G E1 E2 / r^2 is introduced as a postulate, with no derivation. The text itself states 'I doubt that this is possible' concerning consistency with general relativity. Every subsequent capture and acceleration result is a direct consequence of the gamma factor in this assumed law. Under standard rest-mass coupling, the capture radius for a relativistic proton is G M_sun / c^2 ~ 1.5 km, far inside the Sun, so the proposed mechanism fails unless Eq. (14) is independently established. The paper supplies no equivalence-principle test, no ultrarelativistic gravitational-deflection prediction, and no other falsifiable consequence of the modified law.
- [Section 8, 'Double slingshot' and 'Improving the performance'] The paper gives no quantitative flux, spectrum, or arrival-direction prediction. The mechanism is described as 'semi-quantitative', and the expected energy distribution is left as 'As a guess, one hopes/expects...'. This prevents any observational discrimination between solar and galactic cosmic-ray origin. In addition, the static longitudinal electric-field line-integral objection is dismissed with 'Perhaps, or even probably' (bullet 2) that the 22-year solar cycle overcomes it; no model or calculation demonstrates that net acceleration survives the cycle.
minor comments (4)
- [Section 8, Eq. (14)] The symbol r is introduced as 'the radius of the sun' in the sentence after Eq. (14), but is then used as a general radial coordinate. This obscures the derivation and should be fixed.
- [Appendix A] Typos: 'Coles-Notes' should be 'CliffsNotes'; 'read read' appears in the text. A careful proofreading pass is needed throughout.
- [References] Reference [8] is listed twice for the same book; reference [16] is used for two different sources; reference [42] has no author. Several bibliographic entries are incomplete.
- [Section 8, Eq. (16)] Equation (16) identifies KE_A with gamma_A m_A v_A^2/2, which is not the relativistic kinetic energy (gamma_A - 1)m_A c^2 used elsewhere in the paper. This inconsistency should be resolved or the derivation revised.
Circularity Check
The headline solar-capture result is computed from the modified gravitational law that was itself adopted to make solar cosmic rays possible; the 'prediction' restates the input.
specific steps
-
fitted input called prediction
[Section 8, Eq. (14)]
"Fp = G E1E2/r2 ≈ G m1γpmp/r2 , (14) ... I am forced to revise Newton ’s gravitational law in this new way in order to explain how most of the cosmic rays observed in nature, at least up to 106 GeV/nucleus for example, can have been produced within the solar system."
The modified force law is introduced specifically so that relativistic protons feel a γ-enhanced gravitational force and can be captured by the Sun. The subsequent cosmic-ray energies are then presented as consequences of that law, but they are the motivation for the law, not independent predictions. No external data, equivalence-principle test, or parameter-free constraint is used to fix Eq. (14); the solar-capture conclusion is built into the chosen input.
-
self definitional
[Section 8, Eqs. (16)-(18); Section 12, Eqs. (41)-(42)]
"rA−lim = G Msun 2 = 6.6 × 109 m. (18) ... The most persuasive theoretical indication that this replacement of mass by energy may be physically correct comes in the comparison of Eq. (18) and Eq. (19)."
Eq. (18) is just the limiting radius obtained by inserting E≈γm into the assumed force law and setting the kinetic-energy factor to 1. Comparing that computed radius with the observed solar radius is offered as evidence for the force law, but the comparison is a consistency check with no independent predictive content: the force law was chosen so that capture at solar-system scales would be possible. The 'prediction' is the definition of the model, not a test of it.
-
other
[Section 8, Eqs. (17)-(18)]
"Following Eq.(58) in Appendix B, the final factor in Eq. (17) has been set equal to 1."
Eq. (17) contains the factor γ_A m_A / KE_A. Setting this factor to 1 is not a consequence of Eq. (58), which is the non-relativistic approximation E≈E0+mv^2/2; for a relativistic proton the factor is not 1 in the same units. This algebraic choice removes the energy dependence that would otherwise determine the numerical radius, so the claimed 6.6×10^9 m result is effectively inserted by hand rather than derived.
full rationale
The paper contains two distinct projects. The storage-ring sections (Sections 9-11) are concrete accelerator-physics designs and are not circular: they use standard Lorentz-force optics and are checked against internal kinematic consistency. The headline claim, however, is the solar cosmic-ray mechanism, and that claim is circular in the central sense. Eq. (14) is an ad hoc replacement of rest mass by total energy in Newton's law, explicitly adopted 'in order to explain' solar production of cosmic rays up to 10^6 GeV/nucleon. The key quantitative anchor, r_A-lim = G M_sun/2, is then derived from that same equation and exhibited as 'the most persuasive theoretical indication' that the mass-to-energy replacement is correct. That is comparing the model's own assumption with an observed radius, not testing the assumption. The step from Eq. (17) to Eq. (18) further sets the kinetic-energy factor to 1 without justification, making the numerical result an even more direct construction. Thus the central derivation reduces by construction to its input: the gamma factor in the input law produces the gamma factor in the capture condition, and the capture radius is presented as validation. The paper's own admission that it is 'forced' to revise the law and its doubt about compatibility with general relativity reinforce that the premise is not independently established. Score 8: the headline result is forced by definition, while the non-cosmic-ray accelerator material remains independent.

abstract
Begun as part of a promotion of accelerator-based nuclear astrophysics, research toward this goal has shifted to cosmic ray production within the solar system. This has been motivated by the high quality of data collected recently by programs such as the International Space Station (ISS), by the fundamental importance of the topic, and by the unsatisfactory state of our understanding of the actual source of cosmic rays. A ``minor'' change in the Newtonian gravitational formulation converts solar production of high energy cosmic rays from ``impossible'' to ``likely'', without much disrupting the vast existent domain of well understood astronomical gravitational processes. This change enables the sun to ``capture'' protons of energy so high that they would, otherwise, escape the solar system. This change in Newton's gravitational formula would disrupt current cosmological understanding of missing mass and dark energy. With this changed understanding of gravity, it has been quite easy to produce a semi-quantitative understanding of the solar origin of cosmic rays up to energies at least as great as $10^6$\,GeV/nucleon that have by now been detected and measured so persuasively. A ``Double Slingshot'' mechanism is proposed according to which at least a substantial fraction of all cosmic rays could have begun their life within the solar system. Accelerator-based nuclear astrophysics is promoted, beginning with the functioning of an ``{\rm E}\&{\rm M}'' storage ring for laboratory-based study of processes such as ${\rm 6LI} + {\rm 7Li} \rightarrow {\rm 13C} + \gamma$. Especially to be emphasized are experiments made possible by ''rear-end collisions'' between nuclear isotopes of two different types traveling simultaneously at different velocities in the same direction in the same storage ring. This amounts to ``studying nuclear physics in a moving frame of reference''.
