But if repulsive gravity exists, then P is true, see Sect. 1, which leaves that ΣQM is then false. In other words, quantum theory is fundamentally incompatible with repulsive ...

Solving the Time-Independent Schrödinger Equation Abstract

Of course, to do this we need a value for E to use in the integration. Let’s just guess something to start with. Now imagine integrating forward in x until we exit ...
