Is the cosmological coincidence a problem?

The matching of our epoch of existence with the approximate equality of the dark energy and dark matter densities is an apparent further fine-tuning, beyond the already troubling 120 orders of magnitude that separate dark energy from the Planck scale. In this paper I will argue that this coincidence is not a fine-tuning problem, but instead an artifact of anthropic selection. Rather than assuming observations are equally likely in all epochs, one should insist that measurements of a quantity be typical amongst all such measurements. As a consequence, particular observations will reflect the epoch in which they are most easily made. In the specific case of cosmology, most measurements of dark energy and dark matter will be done during an epoch when large numbers of linear modes are available to observers, so we should not be surprised to be living at such a time. This idea is made precise in a particular model for the probability distribution for r ({₌}{_}, {_}{₌}), where it is shown that if p (r) (r) ^b where N (r) is the number of linear modes, and b is some arbitrary positive power, the probability that r is greater than its observed value of 0. 4 is close to 1. Thus the cosmological coincidence is no longer problematic.
