PBT: Gravity

In PBT, gravity isn’t a pull — it’s a net inward push, caused when a mass “shadows” the surrounding particle flux, reducing pressure on the near side relative to the far side. The effect mimics Newtonian attraction and reproduces $G$ from first principles, but the mechanism is mechanical, not geometric.
