Basal Resonance Tunability: Theoretical Foundations of Spacetime Editing

This paper is the first in the Spacetime Editing Theory series, laying the theoretical foundation for subsequent papers. Basal Resonance Tunability (P5) is the fifth core property of the ITC framework, proposed after P1–P4. It asserts that the projection mapping P3 from the basal structure is resonantly sensitive to external physical fields (especially electromagnetic fields) at specific frequencies. When the frequency of an external field matches a basal eigenfrequency, the P3 mapping can be temporarily modulated, affecting the manifestation rules of objects. This paper systematically expounds the definition, theoretical origin, and relationship of P5 with the existing properties, starting from the internal logic of the ITC framework. By revealing the dynamical degrees of freedom of the basal structure through the emergent speed-of-light formula c=1/(ρ1/3τ), we lay the theoretical foundation for spacetime editing.
