Gravity is one of the oldest and most enigmatic phenomena in physics. For Newton it appeared as an invisible force acting at a distance; for Einstein it became the curvature of four-dimensional spacetime. Yet both descriptions reach fundamental limits: galactic rotation curves require invisible dark matter, the accelerated expansion of the universe demands a mysterious dark energy, and the unification with the quantum world remains unresolved to this day. Relational Gravity breaks with this geometric paradigm. It no longer treats gravitation as a primordial property of space and time, but as an emergent phenomenon: the natural balancing pressure exerted by an infinitely dense, highly dynamic vacuum ocean upon condensed, information-bound structures. Wherever matter forms, the local potential pressure of the vacuum drops. The surrounding vacuum then presses back, producing the directed motion we perceive as attraction. What classical physics calls “force” or “geometry” reveals itself here as a low-frequency information flow that permanently restores cosmic unity. This approach resolves central observational puzzles without introducing additional entities. Flat galactic rotation curves arise naturally from a critical acceleration scale below which vacuum pressure dominates Newtonian dynamics. The cosmological constant becomes the residual pressure of the vacuum itself. The Hubble tension simply reflects local density variations within the relational lattice of the cosmos. At the same time, an elegant bridge opens between quantum information flow and relativistic large-scale dynamics. The theory remains strictly falsifiable and firmly anchored in established observations. It does not replace any existing mathematical framework; instead, it supplies its physical origin—thereby providing a unified, information-theoretic foundation for all of physics, from the quantum scale to the cosmic horizon.
