Section 1: What DPΦ proposes
A present-only foundation for physics
Modern physics measures only the present: clocks are read now, detectors click now, records are inspected now. The past is inferred from present evidence. The future is projected from present laws.
Dynamic Present Theory asks what happens if physics takes this boundary literally.
DPΦ keeps the tested mathematical relations of relativity, but rejects the interpretation that spacetime must be a completed four-dimensional block in which past, present, and future equally exist. In DPΦ, spacetime is the map. The actualizing present is the territory.
