Equivalence of Acceleration in Flat and Curved Spacetimes

This paper examines how acceleration is correctly applied to bodies for observers in various frames of reference to show an equivalence of gravitational acceleration as a worldline that follows a straight path through flat spacetime and acceleration due to energy as a worldline that follows a curved path through flat spacetime and so also an equivalence of a uniform acceleration of a body due to energy and that of an inertial body. As well as removing flat and curved spacetime simply by focussing on what is essentially the relative curvature of worldlines it also treats uniform acceleration as inertial motion, removes gravitational singularities and shows that event horizons certainly cannot be reached from or within any reference frame because there's never enough space or time in the universe.
