Abstract
Motivated by both concepts of Adler’s recent work on utilizing Clifford algebra as the linear line element and the fermionization of the cylindrical worldsheet Polyakov action, we introduce a new type of spacetime quantization that is fully covariant. The theory is based on the reinterpretation of Adler’s linear line element as , where is the characteristic length of the theory. We name this new operator the “spacetime interval operator” and argue that it can be regarded as a natural extension to the one-forms in the noncommutative geometry. By treating Fourier momentum as the particle momentum, the generalized uncertainty principle of the noncommutative geometry, as an approximation to the generalized uncertainty principle of our theory, is derived and is shown to have a lowest order correction term of the order similar to that of Snyder’s. The holography nature of the theory is demonstrated and the predicted fuzziness of the geodesic is shown to be much smaller than conceivable astrophysical bounds.
