The Double-Slit Experiment as Temporal Branching in Mass as Twisted Time

Abstract We resolve the foundational mystery of the double-slit experiment within the Mass as Twisted Time (MaTT) framework. In MaTT, a particle is a self-sustaining knot in the temporal manifold. Upon encountering two slits, this knot splits into two synchronized time branches whose relative torsional phases generate interference. When a detector interacts with one path, wavefunction collapse occurs only if the detector introduces a phase mismatch, triggering the Twist–Untwist (TUT) mechanism. Crucially, if the detector remains phase-coherent with the particle, interference is preserved—as confirmed by quantum eraser, Bell test, and GHZ experiments. This provides a causal, geometric account of wave-particle duality, superposition, and entanglement correlations—without postulates of randomness or external observers.
