\section{References}
The following references encompass foundational works in relativity, quantum gravity, and cosmology, as well as contemporary studies up to 2025 on observational data from JWST, LIGO, and other instruments. They cover key topics including spacetime geometry, black holes, Lorentz invariance violations, the arrow of time, unification theories, and the information paradox.
