Rethinking Fundamentals: Gravity, Perceptual Time and Light

This paper is an essay, not a mathematical proof, which tries to raise the questions on the fundamentals of physics. This paper challenges the explanations given by Albert Einstein for his work in the field of Gravity, time, and Light. It presents the thought process of the author with logical questions and supporting explanations. Addressing the inherent limitations of the standard two-dimensional ”rubber sheet” analogy of spacetime, the author proposes a model where gravity is a direct function of material density rather than absolute mass. Through this lens, the study re-examines the mechanics of local gravitational pull and presents a conceptual reassessment of time, treating it not as a fundamental physical coordinate, but as a perceptual metric derived from the rate of change in moving matter. By integrating thought experiments involving human observation under variable gravitational fields and accelerating reference frames, the essay investigates the behavioral limits of light, visual information capture, and the theoretical implications of faster-than-light (FTL) transit on experiencing historical data.
