Quantum Gravity and String Theory

    

The Assumption of Continuity of Spacetime in Quantum Gravity

Authors: René Friedrich

General relativity and quantum mechanics both have been confirmed by experiments. In order to unify them, theories of quantum gravity are becoming more and more ingenious, but without success. The current theories of quantum gravity are based on the assumption of a continuous Lorentzian spacetime manifold. Little attention is paid to this assumption, but no theory is complete without the prior verification of the soundness of its underlying assumptions. Based on the principles of general relativity it will be shown that the assumption may be invalidated for two reasons: - Mathematically, the metric of Lorentzian manifolds is not properly defined, and - Physically, the principles of relativity refer to worldlines, but not to the void between worldlines.
