In one of Feynmans messenger lectures he proved that relativity implies local conservation of energy using the lagrangian (energy can't jump from one place to another). In the atom of quantum theory the electron jumps around in various discrete orbits. This seems like a contradiction.(adsbygoogle = window.adsbygoogle || []).push({});

Is this 'the' problem with unifying relativity and quantum theory? What other problems are there?
