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. Version 14 updates include grammatical corrections and new addendum items 56, 57 and 58. Version 15 complements version 14 and captures key concepts of the theory in a concise and visual presentation. Version 16 is a short video that provides a very simple explanatory overview of Linearity Theory as presented in versions 14 and 15.
