The conception of spacetime as a literal, dynamic grid or lattice of fundamental units (like planck-length cells), where relativity emerges from the properties and connections of this grid. Gravity and motion are results of distortions, twists, or changes in the grid's structure. It's a more ordered, geometric cousin to foam theory, often explored in certain quantum gravity approaches.
Example: "In his Relativistic Grid Theory lecture, he showed a simulation where a mass was just a persistent knot of tighter grid cells, and gravity was the gradual stretching of the surrounding grid lines toward that knot. Falling felt less like a force and more like sliding down a pre-warped slide."
