Time Travel: Temporal Mutability in the Absence of Hardware
This paper introduces the concept of Semantic Time Travel and proposes a formalization as the Recontextualization Principle: any sufficiently revelatory information disclosed in the present can retroactively transform the entire subjective experience of an arbitrary length of past time, without altering any physical events within that timeline. Unlike physical time travel, which requires manipulation of spacetime geometry and faces substantial barriers including lethal radiation, tidal forces, and chronology protection mechanisms, Semantic Time Travel operates on the meaning layer of temporal experience and is not only theoretically possible but observably occurs in human life. Drawing on work in hermeneutics, narrative identity theory, and the neuroscience of memory reconsolidation, this paper argues that for conscious beings, subjective temporal experience may be the only temporality that functionally matters, and that the mutability of meaning across time constitutes a genuine and underexplored form of temporal manipulation.
