Black-Hole–White-Hole Time-Based Navigation Hypothesis

This preprint presents the Black-Hole–White-Hole Time-Based Navigation Hypothesis, a speculative model in which a black hole and a white hole form opposite ends of a connected spacetime navigation system. In the proposed framework, gravity attracts objects toward the black-hole end, negative gravity expels objects from the white-hole end, and multiple wormhole corridors exist between the two ends. Each wormhole corridor is connected to one fixed spatial destination, while the traveler may select the point in time at which to arrive at that destination. The traveler is assumed to be rational, informed, and equipped with advanced structural-scanning and mapping data that identify the correct black-hole system, wormhole corridor, destination, and available time points. The hypothesis also introduces an anti-gravity spacecraft that is unresponsive to both gravity and negative gravity. This technological capability allows the traveler to navigate independently, enter the system from either the black-hole side or the white-hole side, and exit from either side once the route is known. This work is an independent conceptual research proposal intended to organize and develop ideas concerning black holes, white holes, wormholes, time-based navigation, spacetime mapping, fixed destinations, selectable arrival times, and advanced spacecraft control. It is a speculative hypothesis and is not presented as experimentally verified or accepted physical theory.
