Quantum Theory Requires Gravity and Superrelativity

The ordinary quantum theory points out that general relativity is negligible for spatial distances up to the Planck scale lP = (h̄G/c 3)1/2 ∼ 10−33cm. Consistency in the foundations of the quantum theory requires a“soft” spacetime structure of the GR at essentially longer length. However, for some reasons this appears to be not enough. A new framework (“superrelativity”) for the desirable generalization of the foundation of quantum theory is proposed. A generalized non-linear Klein-Gordon equation has been derived in order to shape a stable wave packet.
