Scala Harmonica: The Geometry of Planetary Resonance

What if the geometry carved into ancient Celtic stone crosses encodes the architecture of the Solar System?

In Scala Harmonica, Salah-Eddin Gherbi proposes that planetary orbital spacing follows a precise harmonic sequence derived from the Silver Ratio - a mathematical constant embedded in the geometry of the Celtic Cross. Across nine planets and a predicted missing body between Mars and Jupiter, the model achieves a mean error of just 0.72%, an eightfold improvement over Kepler's nested sol...
