| dc.description | Entropy bounds render quantum corrections to the cosmological constant $Λ$ finite. Under certain assumptions, the natural value of $Λ$ is of order the observed dark energy density $\sim 10^{-10} {\rm eV}^4$, thereby resolving the cosmological constant problem. We note that the dark energy equation of state in these scenarios is $w \equiv p / ρ= 0$ over cosmological distances, and is strongly disfavored by observational data. Alternatively, $Λ$ in these scenarios might account for the diffuse dark matter component of the cosmological energy density. | |
