Query: On the Super-Renormalizablity of Quantum Gravity in the Linear
  Approximation   We compute the one-loop contributions of the chronological products for
massless gravity in the second order of the perturbation theory. We prove that
the loop contributions are coboundaries i.e. expressions which give zero when
averaged on physical states. We conjecture that such a result should be true in
higher orders of the perturbation theory also. This result should make easier
the problem of constructive quantum field theory.
