The Cosmic Relay Paradox is a speculative philosophy-of-physics thought experiment examining the interaction between relativistic time dilation, hypothetical multiverse continuity, and finite biological lifespan constraints. The model imagines a sequential chain of nearly identical universes in which an observer transfers between realities through speculative wormhole or spacetime-bridge technology while traveling at velocities approaching the speed of light. Due to relativistic time dilation, the traveler experiences only a few days of elapsed time while approximately one year passes within the destination universe. As the process repeats across multiple universes, a progressive age displacement emerges between incoming travelers and local observers. The central conceptual tension occurs near the biological lifespan boundary, where a local observer may die naturally shortly before a younger counterpart arrives from another universe, creating the appearance of resurrection or continuity renewal to outside observers. This paper does not propose experimentally verified physics. Instead, it presents a conceptual framework intended to explore questions concerning observer identity, continuity, biological limits, and the philosophical interpretation of relativistic succession across hypothetical parallel realities.
