Contradiction Between the Uncertainty Principle and the Constancy of Light Speed

Quantum mechanics implies uncertainty relations of velocity. So as a velocity, the speed of light will be uncertain. The speed of light should have statistical fluctuations within a small space-time and at high energy. This result contradicts the constancy of vacuum light speed assumed in relativity theory. Some new theoretical researches and new experimental results are discussed briefly. We believe that relativity and quantum theory will be able to be unified completely only after both are further developed.
