SP3 MANIFESTO: Clarifying Spacetime Misunderstandings (Expanded)

This manifesto assumes the correctness of the SP3 (Space-Phase-Three) framework andexpands upon its implications for modern science and public understanding. Manyprevailing interpretations in physics correctly predict outcomes yet misidentify wherephysical effects reside. SP3 proposes that space itself is structured, conditioned by use,capable of storing history, and subject to relaxation. This expanded document explains, inlayperson-accessible language, the major categories of misunderstanding that arise whenspace is treated as passive geometry. For each category, we identify specific anomaliesalready observed, explain why they appear confusing under conventional assumptions,and show how SP3 provides a coherent and testable reframing. The benefits includeclearer interpretation of experiments, improved engineering intuition, and a more unifiedpicture of nature
