The Universe Is Hiding an Extra Dimension, Scientists Say
A team from Istanbul University has introduced a mathematical model that lets the effective number of spacetime dimensions vary with local curvature. By combining the Ricci scalar with fractal‑geometry concepts, the framework predicts extra “effective” dimensions in extreme environments such as the early universe, neutron stars and black‑hole interiors. The model stays within general relativity and fits naturally into scalar‑tensor theory, avoiding the need for additional matter fields. Researchers now have a testable tool to explore high‑curvature physics without overhauling existing theory.
