Quantum gravity without additional theory - Compatibility of Schwarzschild metric and quantum mechanics — •René Friedrich — Strasbourg

Theories of quantum gravity are attempting without success the quantization of spacetime. The present proposal puts forward the fact that the current concept of spacetime is only a mathematical tool which has been developed for the description of the principles of general relativity, and it is based on assumptions which are neither deriving from general relativity nor compatible with quantum mechanics. The following three corrections of the current spacetime concept are opening the way for quantum gravity:

1. Spacetime is no continuous manifold - general relativity defines worldlines but no vacuum points between worldlines.

2. For the solution of fundamental physical problems about time, we must refer to the proper time parameter of worldlines instead of the coordinate time of spacetime.

3. Gravitation may be represented by Schwarzschild metric not only as curved spacetime, but alternatively also as gravitational time dilation in uncurved, flat space.

The result: General relativity and quantum mechanics are perfectly harmonizing, and gravity acts within quantum mechanics in the form of gravitational time dilation.
