  For Riem(M) the space of Riemannian metrics over a compact 3-manifold without
boundary $M$, we study topological properties of the dense open subspace
Riem'(M) of metrics which possess no Killing vectors. Given the stratification
of Riem(M), we work under the condition that, in a sense defined in the text,
the connected components of each stratum do not accumulate.
  Given this condition we find that one of the most fundamental results
regarding the topology of Riem(M), namely that it has trivial homotopy groups,
would still be true for Riem'(M). This would make the topology of Riem'(M)
completely understood. Coupled with the fact that for Riem'(M), we have a
proper principal fibration with the group of diffeomorphisms, which makes
Riem'(M)/Diff(M) a proper manifold (as opposed to Riem(M)/Diff(M)), we would
have that the homotopy groups of the quotient are given by the homotopy groups
of Diff(M), which reflects the topology of $M$. These results would render the
space of metrics with no symmetries subject to the above condition, as an ideal
setting for geometrodynamical analysis.
