I thought about the geometry of Earth by definition and thought of the implications of 'curved space-time'. I understand a trajectory of a satellite and other objects to be straight geodesics through warped space-time. Would the Earth then therefore be able to described as a straight surface in this non homogeneous space-time continuum and in a sense, 'flat'?
I am presuming flat to mean a surface that is straight so that a tangent vector is always touching the surface.
