GNO achieves 0.31% mean EFE residual

Fourier Neural Operator resolves strong-field perturbations that NR codes miss at low resolution

KEY FINDING 2

Bianchi identity enforced as hard constraint (4.7×10⁻⁴)

Divergence-free projection layer ensures energy-momentum conservation

KEY FINDING 3

10⁷× inference speedup vs numerical relativity

47 ms per waveform vs 14,000 CPU-core-hours for SpEC

KEY FINDING 4

Centimeter-level geodesic accuracy (1.8 cm RMS)

24-hour GPS prediction with M-GAN correction for non-tidal loading
