Dark Matter as Gravitational Shadow: Dual Universes, Entanglement, and Cosmic Isolation

This paper proposes a speculative conceptual model in which dark matter arises from gravitational influence originating in companion universes produced through cosmic mitosis. Building on the earlier paper From the Fermi Paradox to Cosmic Mitosis, this work shifts from biological analogy to physical symmetry, exploring the possibility that universes form in +/– pairs whose quantum states remain entangled. In this model, matter in a “negative” universe does not interact electromagnetically with matter in a “positive” universe, rendering each universe invisible to the other except through gravity. Dark matter is interpreted as the gravitational imprint of these companion universes. The model draws conceptual support from brane cosmology, CPT-symmetric universe theories, and studies of entanglement across cosmological horizons. It is offered not as a testable theory, but as a continuation of interdisciplinary reflection on replication, isolation, and structure at universe scale.
