This paper, the fifth in the Spacetime Editing Theory series, envisions the world that may emerge after humanity acquires the ability to edit spacetime, exploring this prospect from two dimensions: technological prospects and philosophical significance. Building on the theoretical and experimental groundwork of the preceding papers, we analyze the path from single‑frequency resonance to multi‑frequency superposition for achieving macroscopic displacement, introduce the concept of a “frequency fingerprint library,” and envision the embryonic form of teleportation technology—from controllable manifestation port switching to remote object transfer, and further to interstellar teleportation and spacetime editing. Furthermore, we discuss the implications of spacetime editing for the nature of spacetime: the speed of light, as an emergent quantity, can be locally modulated, making spacetime itself an editable manifestation layer. Viewed from a philosophical dimension, spacetime editing establishes the basal structure as an invisible yet real physical reality (just as gravitational fields, though invisible, are perceived through the free fall of objects; magnetic fields, though invisible, are confirmed by the deflection of compass needles), thereby opening a new ontological dimension for physics. Regardless of the experimental outcome, the exploration itself has already opened a new dimension in human understanding of reality.
