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

The apparent incompatibility of the current spacetime concept with quantum mechanics seems to be the main obstacle of quantum gravity. But as it will be shown here, our spacetime concept is based on assumptions which are not only contradicting quantum mechanics, but also the two postulates of special relativity and the Schwarzschild metric.

The following three corrections of the current spacetime concept are necessary to avoid these contradictions:

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.
