Gravity as E·B Field Output
Pre-mission predictions for Artemis III — stated April 20, 2026, before mission data is available
MPRC Gravity Framework and Falsifiable Predictions
The MPRC (Movement-Position-Rotation-Charge) framework derives gravitational force as the inward E·B field output of a discrete Z256 ring geometry. The central result:
Newton's inverse-square law is identified as the geometric projection of MPRC onto flat coordinate space. The tilt angles θ₁, θ₂ are the frame conversion factors — not corrections.
Three falsifiable pre-mission predictions are stated for NASA's Artemis III lunar landing (scheduled 2027): E-field gradient at −89°S, vacuum micro-discontinuity at 12 km altitude during powered descent, and a discrete frame transition in the NRHO trajectory at 18,454 km from Moon center.
Mission status: Artemis III not yet launched (scheduled late 2027). All predictions stated before any mission data is available.
The Z256 Ring Geometry
The fundamental state space is a discrete ring of 256 positions:
Charge is not a primary input — it is the output of E·B:
Vacuum Boundary Altitudes
With Earth's 23.5° tilt correction, the Z256 vacuum boundaries map to:
| u | Altitude (km) | Nearest satellite | Separation (km) |
|---|---|---|---|
| 0 | 576.2 | Hubble (540 km) | 36 |
| 64 | 10,372 | LAGEOS-1 (5,900 km) | 4,472 |
| 128 | 20,168 | GPS IIF (20,184 km) | 21 |
| 192 | 29,964 | Galileo (23,222 km) | 6,742 |
GPS IIF sits 21 km from the u=128 vacuum boundary. This was not fitted — it emerged from the Z256 geometry with Earth tilt applied.
The Drag Formula and Frame Conversion
For two gravitationally interacting bodies with masses M₁, M₂ at distance r:

GPS Time Dilation
Anomalous Acceleration Pattern
Published non-gravitational accelerations (Rodriguez-Solano et al. 2017). Pattern: anomalous acceleration increases with distance from vacuum boundary. Newton and Einstein provide no structural prediction for this correlation.
| Satellite | Anomalous acc (m/s²) | Distance from u=128 (km) |
|---|---|---|
| GPS III | 0.6×10⁻⁹ | 21 |
| Galileo | 0.7×10⁻⁹ | 3,061 |
| GPS IIF | 0.9×10⁻⁹ | 21 |
| GPS IIA | 1.2×10⁻⁹ | 21 |
| GLONASS | 1.8×10⁻⁹ | 1,031 |
Prior Lunar Observations
E-Field Gradient Toward South Pole
Two prior missions measured the surface electromagnetic environment near the lunar south pole:
| Mission | Latitude | E-field | Instrument |
|---|---|---|---|
| IM-1 Odysseus (Feb 2024) | −80°S | < 1.0 mV/m | ROLSES |
| IM-2 (Mar 2025) | −84°S | ~ 2.1 mV/m | MAPP |
A 2.1× increase over 4 degrees of latitude toward the pole. MPRC predicts this gradient continues toward the pole axis endpoint — the lunar south pole is the endpoint of the Z256 u'-clockwise axis.
NRHO Properties (Artemis III vs Apollo)
| Parameter | Apollo LLO | Artemis III NRHO |
|---|---|---|
| Perilune | 110 km | 1,500 km |
| Apolune | 313 km | 70,000 km |
| Period | 2 hours | 6.56 days |
| Earth gravity at apolune | negligible | 201% of Moon gravity |
NRHO sweeps u = 6 → 255 in Moon Z256 frame — the widest sweep of any lunar mission. Crosses vacuum boundaries at u=64, 128, 192 each orbit. In Moon's frame:
Three Falsifiable Pre-Mission Predictions
All predictions stated: April 20, 2026. Artemis III is scheduled for late 2027.
P1 basis: The lunar pole is the endpoint of the Z256 u'-clockwise axis. The inward E·B field strengthens as u-position approaches the axis endpoint. The gradient observed from IM-1 to IM-2 is consistent with this geometry.
P2 basis: T_drag = 0 at vacuum boundary positions. Standard powered descent trajectory crosses the u=0 vacuum boundary during the terminal phase. Both Newton and Einstein predict smooth, monotonically increasing gravitational acceleration. MPRC predicts a discrete structure at the boundary crossing.
P3 basis: MPRC has distinct Z256 ring frames per gravitational body (Earth: 23.5°, Moon: 6.68°). The frame transition where Earth and Moon T_drag contributions are equal is a discrete boundary. Standard CR3BP treats this transition as continuous.
Summary
| Prediction | Value | Measurable when |
|---|---|---|
| P1 — E-field at −89°S | > 2.1 mV/m (est. 4–6 mV/m) | Surface operations |
| P2 — IMU discontinuity at ~12 km | Anomalous deceleration signature | Powered descent |
| P3 — NRHO residual step at 18,454 km | Systematic trajectory bias | Orbital phase |
Prior Observations Supporting the Framework
| Observation | Value | Source | MPRC status |
|---|---|---|---|
| GPS IIF altitude | 20,183.5 km | IS-GPS-200H | 21 km from u=128 vacuum |
| GPS III anomalous acc | 0.6×10⁻⁹ m/s² | Rodriguez-Solano 2017 | lowest — nearest vacuum |
| GLONASS anomalous acc | 1.8×10⁻⁹ m/s² | Rodriguez-Solano 2017 | highest — farthest from vacuum |
| IM-1 E-field at −80°S | < 1.0 mV/m | Farrell et al. 2024, GRL | consistent with axis prediction |
| IM-2 E-field at −84°S | ~ 2.1 mV/m | MAPP instrument 2025 | gradient matches MPRC |
| GPS time dilation | +38.61 μs/day | calculated | measured +38.4 μs/day — PASS |
Honestly Stated Open Questions
The following items are not resolved and are honestly stated as open:
- LAGEOS-1 outward field magnitude — direction of the 0.35 mm/day residual matches MPRC prediction, but the magnitude calculation requires refinement of the outward field formula.
- Chang'e-6 far-side tension — Chang'e-6 landed at −41°S on the lunar far side (June 2024). The South Pole-Aitken Basin shows −600 mGal anomaly. MPRC predicts the far side is on the u'-clockwise (inward) axis, which should produce stronger gravity. The −600 mGal reading is in tension with this prediction. Possible explanation: SPA Basin mascon deficiency from impact-related iron depletion dominates over the E·B field contribution.
- z3 derivation — the oloid projection factor z3 = z4·|sin θ| was verified numerically but needs a complete formal proof.
- Arshad's Sieve connection — the Z256 ring structure connects to Arshad's Sieve modular framework; this connection is not yet formally derived.
MPRC does not replace Newton or Einstein — it extends them. Newton is verified as the geometric projection of MPRC. Einstein's weak-field limit (GPS time dilation) is reproduced exactly. Open questions are acknowledged, not swept under the rug.
