This paper proposes a model of sensory dimensional evolution, aiming to elucidate thepotential biological significance of quantum mechanics and provide a new explanatoryframework for issues such as the observer effect and the Fermi paradox. The model isbased on two fundamental assumptions: first, the universe possesses a highest dimension; second, the evolution of sensory systems is closely related to dimensional cognition.Building on this foundation, the paper attempts to construct an interdisciplinary theoretical system to connect biological perception mechanisms with fundamental physicallaws, and to provide a unified description for the pathways of civilizational evolution, theforms of alien civilizations, and their differences in world cognition.
