as mass moves through spacetime, it follows the geodesics of local spacetime curvature as rendered by nearby large masses such as stars, planets, etc (and all other mass to whatever degree).
how does mass know that the spacetime through which it passes is curved? ie, how is the curvature of a geodesic imparted to a particle of mass? i know the particle thinks it is just moving along a "straight" line, but from my observer perspective, it looks like a curve to me...
