The coincidence problem in cosmology asks why the densities of dark matter and dark energy in the Universe are comparable today. A possible approach to this problem is to consider dark matter and dark energy not as separately evolving fluids, but as two fluids that interact with each other. We examine a natural form of interaction and discuss its consequences, including the result that it is possible to get solutions in which the ratio of the dark densities varies periodically.
