GRT - well proven and also incomplete. Further arguments. — •Jürgen Brandes — Karlsbad, Germany

There are two contradictory formulas of the total energy of a particle resting in the gravitational field [1],[2]. From the formulas of radial free fall one gets: E=mc2(1−2GM/c2r). On the other side, there is the equivalence principle. A particle resting in its local inertial system (i.e. the freely falling particle) has a total energy equal to its rest mass: E=mc2. Both of the formulas contradict each other since it doesn’t matter whether the particle is at rest in the gravitational field (t=0, v=0, b=0) or becomes accelerated (t=0, v=0, b≠0) [2]. Lorentz-interpretation (LI) of GRT solves this contradiction with the assumption that standard clocks in gravitational fields run slower by a factor sqrt(1−2GM/c2r). The talk proves this assumption in a larger context using the energy relation of arbitrarily moving particles. These considerations are not really difficult. In spite of this, they become rejected by arguments which contradict each other [2].

The educational consequences of the differences between classical GRT and LI will be discussed, details s. [2].
