Query: The impact of a random metric upon a diffusing particle   We show that if the singularity of the quantized gravity propagator is $\vert
{\bf x}\vert^{-2\gamma}$ then the mean value of the fourth power of the
distance achieved in time $t$ by a diffusing particle behaves as
$t^{2(1-\gamma)}$ for a small $t$.
