What physics emerges once we can actually compute string theory's hidden dimensions?

String theory compactifies on Calabi–Yau manifolds, but only their abstract topological shape mattered—the actual geometry was never computed. New numerical methods now let physicists calculate the real metric, enabling concrete calculations of matter particle properties, Yukawa couplings, and Kaluza–Klein spectra in four dimensions, plus tests of exotic scenarios like de Sitter space and axion physics.
