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

The current notion of spacetime depends on three assumptions which are in contradiction to special relativity and to the Schwarzschild metric, and this is the reason why the quantization of spacetime cannot work. Instead, the key to quantum gravity is the abandon of these three assumptions and the limitation of the notion of spacetime to its actual role, by the means of three insights:

1. Spacetime is not continuous, in particular not in spacelike direction, and thus it cannot be quantized.

2. For the solution of fundamental problems of physics about time, we must consider the notion of proper time instead of the coordinate time of spacetime.

3. Gravitation may be represented by Schwarzschild metric not only as the curved spacetime, but alternatively also as gravitational time dilation in absolute, uncurved space. From these three insights are following the characteristics of quantum gravity. The result: Gravity appears within quantum mechanics in the form of gravitational time dilation.
