Linearity: A New Theory on the Physical Nature of Gravitational Interactions

Linearity Theory introduces a new gravitational framework where space is treated as a dynamic, three-dimensional tensile medium, and gravity is seen as a consequence of pressure-like interactions between matter and space. Unlike traditional field models that depend on void space or abstract spacetime curvature for gravitational interactions, this theory relies on a foundational equation derived from mass pressure and geometry, and a new universal gravitational constant with a unique physical interpretation. The theory proposes that gravitational effects are initiated through space-mass interactions and evolve linearly through a defined sequence of spatial transformations. It is a theory grounded in simplicity, but with implications that span cosmology, relativity, black hole physics, and quantum scale phenomena. The work is a standalone contribution to gravitational physics and invites further theoretical and observational exploration.
