Relativistic Implications for Physical Copies of Conscious States Andrew Knight
[email protected] (Dated: May 11, 2020) The possibility of algorithmic consciousness depends on the assumption that conscious states can be copied or repeated by sufficiently duplicating their underlying physical states, leading to a variety of paradoxes, including the problems of duplication, teleportation, simulation, self-location, the Boltzmann brain, and Wigner's Friend. In an effort to further elucidate the physical nature of consciousness, I challenge these assumptions by analyzing the implications of special relativity on evolutions of identical copies of a mental state, particularly the divergence of these evolutions due to quantum fluctuations. By assuming the supervenience of a conscious state on some sufficient underlying physical state, I show that the existence of two or more instances, whether spacelike or timelike, of the same conscious state leads to a logical contradiction, ultimately refuting the assumption that a conscious state can be physically reset to an earlier state or duplicated by any physical means. Several explanatory hypotheses and implications are addressed, particularly the relationships between consciousness, locality, physical irreversibility, and quantum no-cloning. I. INTRODUCTION scious states cannot be copied, then these and other prob- lems disappear. Whether each of the above scenarios is Either it is physically possible to copy or repeat a con- actually possible is an empirical question, and given the scious state or it is not. Both possibilities have profound rate that technology is advancing, it may be just a matter implications for physics, biology, computer science, and of time before each is tested.
