This paper presents an interpretation of gravity from the perspective of the Light Universe Theory. Unlike conventional approaches, this theory does not assign physical attributes to space and does not employ the concept of spacetime curvature as a physical entity. Building on the observation that Einstein himself treated spacetime curvature as a mathematical representation of the gravitational field, the Light Universe Theory is positioned as an alternative interpretation that preserves the equations and predictions of general relativity. The study demonstrates that gravitational phenomena can be consistently understood without attributing physical properties to space, providing a supplementary framework for understanding gravity.
