PBT: Subatomic Particle

The foundational object in PBT: infinitely small, infinitely numerous particles moving at speeds far exceeding $c$, filling an infinite pressure vessel — similar in kind to air or water molecules, though not identical to either. See Pressure for what that actually means: these particles aren’t a cause that generates pressure, their presence is pressure, the same direct way air pressure exists in a room. 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; Pressure clarifies the existing-vs-emergent distinction specifically.
