PBT: Subatomic Particle

The foundational object in PBT: infinitely small, infinitely numerous particles moving at speeds far exceeding $c$, filling an infinite pressure vessel. Every force in the theory — gravity, electromagnetism, spin — is a different consequence of how these particles flow, bounce, and shadow each other at different scales.

Covered in: Paper 1 sets out the core assumptions; The Theory gives the plain-language overview.
