Revealing the Absolute Space according to the Universal Theory of Reality (TUR)

No experiment to date has directly verified whether physical space possesses an absolute reference frame. All tests on the constancy of the speed of light — such as the Michelson–Morley and LIGO experiments — use two-way optical paths, where directional asymmetries cancel out. This study, based on the Universal Theory of Reality (TUR), proposes an alternative approach: gravity is described as a discrete flux of gravitons propagating at finite velocity (cg ≈ c) through a quantized spatial lattice. By analyzing the radial motion of interplanetary probes, asteroids, and interstellar objects, a small additional term proportional to vr/cg is predicted. This allows the determination of the absolute velocity vector of the Sun relative to the discrete space. Existing data from Pioneer, Voyager, and 3I/Atlas trajectories could thus reveal the presence of an absolute spatial flow. A non-zero result would constitute indirect evidence of the discrete structure of space and validate the quantum-gravitational framework of the TUR.
