The study of Unidentified Anomalous Phenomena (UAP) suggests revisiting Maxwell's expanded electrodynamics, particularly its scalar components, to explore the possibility of UAP operating within an unknown higher-dimensional energy domain. However, the Lorenz gauge presents challenges in decomposing vector fields, while Heaviside's modifications obscure the role of the scalar field in electromagnetism. Restoring this scalar component could bridge electromagnetism and gravity, aligning with General Relativity and introducing new terms in Gauss's law and the Ampère-Maxwell law. This perspective may not only help unravel UAP mysteries but also inform the development of advanced aerospace technologies and trans medium craft capable of superluminal transits.
