We investigate theoretically the effects of a dynamically increasing medium index on optical-wave propagation in a rubidium condensate. A long pulsed pump laser coupling a D2 line transition produces a rapidly growing internally generated field. This results in a significant optical self-focusing effect and creates a dynamically growing medium index anomaly that propagates ultraslowly with the internally generated field. When a fast probe pulse injected after a delay catches up with the dynamically increasing index anomaly, it is forced to slow down and is prohibited from crossing the anomaly, thereby realizing an ultraslow optical-matter wave analog of a dynamic white-hole event horizon.

Wave-particle duality and action at a distance remain among the most conceptuallychallenging observations in modern physics. Conventional physics successfully predictsthe associated phenomena but often treats them as fundamental paradoxes orconsequences of mathematical formalism. Space-Phase Theory (SP3) offers an alternativeinterpretation in which both phenomena are natural consequences of the organizationalbehavior of a continuous, conditionable three-dimensional medium. In this view, matterremains durable and localized, while wave behavior, propagation, coherence, and apparentnonlocality are properties of the space-phase medium itself. Wave-particle duality andaction at a distance are therefore interpreted not as fundamental mysteries of matter, butas fingerprints of the medium through which matter and energy propagate.
