Motivated by and generalizing the Cross-Newell energy functional for pattern
forming systems, we propose a modification of the Einstein-Hilbert action on
galactic scales. We introduce additional terms that reflect the presence of
phase hyper surfaces connected with patterns related to the clumping
instability of baryonic matter. The resulting pattern structures carry an
additional energy density which, remarkably, accounts for many of the phenomena
that are generally attributed to dark matter.
