Yet when a mathematical structure encodes a network of dualities, does it thereby acquire independent spatial ontology? The answer is no. Description is not identity, and predictive success is not ontological licensing. The structure M-theory discovered is real, and it has been misplaced. Dirichlet branes are defined by termination; the holographic principle defines a surface by encoding. In the D3-brane cons...

This paper proposes that strings are fundamental degrees of freedom of the radiation domain (τ=0), not localized material objects at the Planck scale, building on a redefinition of the matter–radiation boundary and a dimensional-separation argument distinguishing the radiation domain from a matter domain with τ>0. Under this identification, several otherwise puzzling features acquire a common explanati...
