Abstract Fossilized Space Theory is a speculative cosmological framework proposing that remnants of previous universal states may survive the formation of a new universe by becoming embedded, compressed, or topologically preserved within emergent spacetime. Rather than treating a Big Bang-like event as a complete erasure of prior cosmic structure, this framework explores the possibility that certain features of an earlier universe could persist as fossil-like imprints in geometry, quantum fields, vacuum structure, entropy gradients, or large-scale cosmic organization. These remnants would not necessarily appear as ordinary matter, stars, planets, or galaxies from a previous universe. Instead, they may exist as subtle spacetime scars, field discontinuities, gravitational anomalies, information residues, or background-radiation irregularities. Version 1 of this theory establishes the conceptual vocabulary, possible mechanisms, observational targets, and limitations needed for later development. The theory is presented as an exploratory hypothesis intended to stimulate discussion, modeling, and future refinement rather than as a confirmed physical model.
