Query: General Solution for the Static, Spherical and Asymptotically Flat
  Braneworld   The general solution for the static, spherical and asymptotically flat
braneworld is derived by solving the bulk Einstein equation and braneworld
dynamics. We show that it involves a large arbitrariness, which reduces the
predictability of the theory. Ways out of the difficulty are discussed.
