Abstract
This paper proposes a novel mind-structured model of reality, the Growing Mental Block of Spacetime (GMB), arguing that space, time, and physical phenomena emerge from an expanding cognitive construct rather than a static, pre-existing structure. Unlike the traditional Block Universe model, which assumes a fixed past and future, GMB suggests that reality grows as a mental framework, structured through awareness, with consciousness functioning as the latent dark medium from which all experience emerges. Drawing from quantum mechanics, cognitive science, and metaphysical idealism, this model resolves paradoxes such as the observer effect, non-locality, and memory as real-time access. We further explore the implications for free will, intelligence, and the evolving nature of reality itself.
