Cosmic Projection Theory: A Dimensional Lock Model via Single-Particle Dual-Helical Vibration and Decoherence under L1-Norm Boundary Conditions

This paper proposes a new dynamic model in which the structure of spacetime is formed by ultra-high-speed projection from a single fundamental information source. We formulate the boundary conditions of spacetime as a regular octahedral (diamond-type) geometry based on the L1 norm, |x| + |y| + |z| + |ct| = k and define its center as the ``Zero-Point''. Matter and the four fundamental interactions emerge when an Information Selection Operator induces a ``Dimensional Lock'' on double-helix waves at specific geometric coordinates. This model explains the attenuation of gravity as geometric dispersion, providing a solution to the hierarchy problem without the need for extra dimensions.
