The Cognitive Perceptual Dimensional Time Relativity (CPDTR) Theory proposes a novel framework for understanding how subjective experiences of time, space, and dimensionality are modulated by cognitive capacity, energy levels, and observer-object dynamics. While time remains an absolute constant, its experiential quality is shaped by an individual's intelligence, speed of motion, and spatial positioning relative to observed objects. By integrating contemporary insights from physics and neuroscience with rich examples from Hindu philosophical traditions-such as Krishna's universal form and the myth of King Kakudmi-the CPDTR Theory contends that high-energy, cognitively advanced beings can access and perceive additional dimensions. This paper delineates five core concepts that together illustrate how our conscious experience of time and space is a relative phenomenon, despite the underlying constancy of physical laws.
