The curvature of space time depends on the distribution of mass and energy within that space time. If you're modeling general relativity classically with quantized mass and energy at very small scales, stuff gets "weird". If a particle isn't in a well-defined location with a well-defined energy, then what is its effect on the curvature of space time around it?
