A Unified Digital Physics Framework: Unifying Relativity and Quantum Mechanics via Discrete Computational Latency

Modern cosmology and quantum mechanics are constrained by structural incompatibilities, relying on unobservable physical constructs—such as Dark Matter, continuous singularities, and non-local paradoxes—to reconcile continuous mathematics with discrete empirical observations. This paper introduces a paradigm shift, remodeling physical reality not as a continuous geometric manifold, but as a resource-constrained, discrete computational network (the NavMesh). By defining the universe as an underlying operating system executing a spatial rendering loop, we demonstrate that physical constraints are hardware limitations. At the macro-scale, we resolve the Hubble Tension as a network artifact of Timestamp Desynchronization between local and wide-area queries, and redefine galactic rotation curves and Einstein Rings as "Lazy Evaluation" pathfinding algorithms, eliminating the need for dark matter. At the micro-scale, this framework provides a strictly mechanical resolution for quantum phenomena: wave-function collapse is redefined as a forced system call for coordinate updates; electron jumps are quantized processing delays; and quantum entanglement is recontextualized as shared database pointers, preserving causality while bypassing the spatial rendering engine. Furthermore, we resolve the empirical "negative time" paradox in quantum optics (e.g., Steinberg et al. [8]) as a localized processing lag (Latency Bubble) rather than a temporal reversal. Finally, we propose two explicit, falsifiable experiments—orbital quantum timestamp drift and attosecond temporal quantization—presenting a direct challenge to the global physics community to test the computational boundaries of spacetime.
