Query: Connection between a possible fifth force and the direct detection of
  Dark Matter   If there is a fifth force in the dark sector and dark sector particles
interact non-gravitationally with ordinary matter, quantum corrections
generically lead to a fifth force in the visible sector. We show how the strong
experimental limits on fifth forces in the visible sector constrain the direct
detection cross section, and the strength of the fifth force in the dark
sector. If the latter is comparable to gravity, the spin-independent direct
detection cross section must typically be <~ 10^{-55} cm^2. The anomalous
acceleration of ordinary matter falling towards dark matter is also
constrained: \eta_{OM-DM} <~ 10^{-8}.
