The pull and push that we feel when our vehicle accelerates, brakes and turns are physical manifestations of inertia — not the inertia of not getting up in the morning but the 'inertial-reel seat-belt' type of inertia that causes a body to remain at rest or retain its velocity along a straight line in the absence of an external force. The nature of 'classical' inertia, generally defined in terms of Newton's first law of motion, and the inertial frame dragging associated with a spinning mass according to Einstein's theory of general relativity, have long fascinated physicists. In a Review Article, Ignazio Ciufolini considers recent developments in the understanding of inertial dragging based on measurements made from Earth-orbiting satellites. The cover image shows gravity anomalies derived from the global gravity potential model EIGEN-GL04C using precise gravity data from NASA's GRACE mission. Earth's rotation drags space — and even time — with it, illustrating inertial frame dragging on a grand scale.
