Quantum gravity without trouble

A large panorama of innovative suggestions and ideas for people interested in physics. Instead of complex theories and mathematical speculation, direct possibilities of pertinent simplification are shown, so that general relativity including quantum gravity is becoming accessible to a large audience. Prior knowledge of special relativity is recommended, but an overview is provided in the introduction.Contents:- Special relativity, briefly- The nature of time- The mistaken assumption of a spacetime manifold- Quantum gravity by elimination of spacetime- Black holes: the infinity at the event horizon- Gravitational attraction and repulsion- Understanding the wave-particle duality of light
