A Fifth-Coordinate Transit Pod: Timing and Energy Budget for an Earth-Moon Crossing Under the Transit Law

This paper presents a complete design study of the device is a crewed transit pod of one to five tonnes that crosses between Earth and Moon not by thrust along the ordinary path but by a brief excursion through a fifth coordinate, entering and leaving ordinary space at powered gate structures at each end, derived from stated assumptions and computed throughout by the accompanying script. At transit parameter 1.0 the crossing takes 1.684 s, against a light time of 1.282 s and a chemical reference of three days, while a 1000 kg pod at the stated coupling efficiency requires 2440482.665 TJ. Time saturates with the parameter while cost grows hyperbolically, producing a clear knee in the trade. Every figure in the study is a computed result of the stated model and nothing was built or tested: the study is SIMULATED, NOT MEASURED, and its limits are stated as plainly as its performance.
