The current study proposes a novel theory, the consciousness-entropy field theory (CEFT), with a conceptual framework, particularly through the lens of string theory. We hypothesize that the frequency of energy vibration is modulated by consciousness, suggesting fundamental consciousness field Ψ(𝐫, 𝑡) that dynamically interacts with the vibrational modes of strings. This interaction implies that the vibrational states of strings are emergent phenomena influenced by consciousness rather than purely fundamental entities. Moreover, we posit a profound connection between entropy and consciousness, where the latter modifies entropy in physical systems, thereby affecting their evolution. Through a series of mathematical derivations, including the mass-energy relationships, we introduce a modified wave equation that considers the conscious state as a determinant in energy dynamics and ultimately leads to a new consciousness-entropy quantum equation (CEQE) and consciousness-entropy field equation (CEFE). Furthermore, we explore the implications of consciousness within the general relativity framework, suggesting potential modifications to the stress-energy tensor that account for the consciousness field. By examining the role of consciousness in quantum interference phenomena, we propose experimental pathways to validate our framework, opening avenues for further research that connects consciousness studies with theoretical physics. The current theory opens a new branch of research area which combines quantum mechanics, general relativity, and the nature of consciousness.
