I'm a string theory novice and am looking for insight from those knowledgeable, interested, or willing to research.

Does string theory work because its strings are structures that include both position and momentum in a single value, an entity smeared out as a vibrating multidimensionality?

If this is an accurate description, it makes sense that the theory can readily synthesize quantum mechanics with gravitational relativity because a single "position/momentum" object eliminates fuzziness of the uncertainty principle as it applies to quantum-scale phenomena, converting "quantum corrections" as addressed to the inherent randomness characteristic of quantum calculations into an exact value or values so that spatial curvature and time dilation/contraction correlate with a quantum object in a likewise precise manner.

If, for instance, the spatial relativity within an electron's region of influence can be represented using a string model, does the theory regard a trillion electrons as a trillion separate strings or blended into a single string? Could a filled electron orbital be a complementary electron and selectron pairing with a shape modelable as a string a la string theory, a position/momentum object smeared out to nanoscale size because of its relatively large momentum?
