In mathematics, particularly differential geometry, a geodesic is
a generalization of the notion of a "straight line" to "curved
spaces" and represents the shortest distance.

See: http://en.wikipedia.org/wiki/Geodesic

From an inertial reference frame c represents the fastest propagation
speed with material objects always with velocity less than c.
