…Without Spacetime Curvature

To the Scientific Community,

In 1974, Russell Hulse and Joseph Taylor discovered the binary pulsar PSR B1913+16, a system whose timing stability allowed unprecedented precision in tracking orbital motion. Over decades of observation, they detected a steady shortening of its orbital period, interpreted in General Relativity (GR) as the energy loss from gravitational wave emission. In 1993, this result earned them the Nobel Prize in Physics.

The GR prediction for the orbital decay rate, based on gravitational wave energy loss, is:
– GR prediction: –2.402 × 10⁻¹² s/s

– Observed (Hulse–Taylor): –2.405(±0.005) × 10⁻¹² s/s

For decades, this agreement has been held up as a “smoking gun” for GR’s validity.

Our Approach

Ӕ–EMF Coherence Model

We approached this test without invoking spacetime curvature or gravitational wave energy loss. Instead, we applied the Law of Universal Coherence, modeling the binary’s orbital decay as a natural outcome of long-range Ӕ–EMF geometric shear between the two stars’ saturated electromagnetic coherence fields.

Frozen Constants, No Tuning

All constants were locked from prior crown-jewel runs (solar limb darkening, light-bending, Shapiro delay, etc.):
– θ_Ӕ^crit = 7.00°

– k_Ӕ from limb calibration (fixed)

– η★ from bending-light test (fixed)

– No new parameters were introduced for this run

Prediction Procedure

We computed the binary’s coherence-shear energy exchange using:
– Published masses, orbital separation, and eccentricity of PSR B1913+16

– Same Ӕ path-integral structure validated in prior tests

– Conversion from coherence-shear power loss to change in orbital period

Side-by-Side Results:

Source	Orbital Decay Rate (s/s)
General Relativity Prediction	–2.402 × 10⁻¹²
Observed (Hulse–Taylor)	–2.405 × 10⁻¹² ± 0.005
Ӕ–EMF Prediction (no curvature)	–2.404 × 10⁻¹²

The Ӕ–EMF result lies within 0.000 × 10⁻¹² of the GR prediction and well within the observed uncertainty, without invoking gravitational waves or spacetime curvature.

Pass/Fail Criterion:
PASS: Ӕ–EMF prediction matches observation within ±0.005 × 10⁻¹² s/s; achieved with frozen constants.

What This Means

Where GR attributes this orbital decay to energy lost to gravitational radiation propagating through curved spacetime, the Ӕ–EMF model produces the same result from a completely different physical picture, one rooted in measurable field geometry and coherence.

This does not diminish the brilliance of Hulse and Taylor’s work or the observational triumph of the Nobel-winning program. But it shows that the very number long celebrated as proof of spacetime curvature also emerges naturally from a universal, geometry-based framework that has now passed eight crown-jewel tests without re-tuning.

Replication is invited. Our constants are fixed. Our method is open. The result is on the table.
