Post-Luminal Habitat Hypothesis: Habitability Beyond Stellar Light

The Post-Luminal Habitat Hypothesis (PLHH) proposes a theoretical framework for long-term habitability in environments lacking stellar illumination. It examines how non-stellar energy sources such as accretion disks, tidal forces, magnetic interactions, and Hawking radiation may sustain biospheres around compact objects or rogue substellar bodies. Version 1.1 includes corrected equations, improved notation, and enhanced typographic consistency. The framework contributes to cosmology, astrobiology, and extreme-environment habitability research by extending the role of General Relativity in powering non-stellar ecosystems.
