Over billions of years, Mercury has been quietly folding inward upon itself, its enormous iron core cooling and contracting until the rigid crust above had no choice but to buckle into great cliffs and ridges stretching hundreds of kilometers across the surface. Scientists reading this geological record from NASA's MESSENGER data disagree on the scale — somewhere between one and seven kilometers of radius lost — a difference that carries profound implications for how much heat the planet has shed and how its faint magnetic field has persisted. The debate is not merely technical; it is a questi
