  The AdS/CFT correspondence between conformal field theory and string states
in an extended space-time has provided new insights into not only hadron
spectra, but also their light-front wavefunctions. We show that there is an
exact correspondence between the fifth-dimensional coordinate of anti-de Sitter
space $z$ and a specific impact variable $\zeta$ which measures the separation
of the constituents within the hadron in ordinary space-time. This connection
allows one to predict the form of the light-front wavefunctions of mesons and
baryons, the fundamental entities which encode hadron properties and scattering
amplitudes. A new relativistic Schr\"odinger light-cone equation is found which
reproduces the results obtained using the fifth-dimensional theory.
