  Within the quantum Darwinist framework introduced by W. H. Zurek ({\em Nat.
Phys.}, 5:181-188, 2009), observers obtain pointer-state information about
quantum systems by interacting with a local sample of the surrounding
environment, e.g. a local sample of the ambient photon field. Because the
environment encodes such pointer state information uniformly and hence
redundantly throughout its entire volume, the information is equally available
to all observers regardless of their location. This framework is applied to the
observation of stellar center-of-mass positions, which are assumed to be
encoded by the ambient photon field in a way that is uniformly accessible to
all possible observers. Assuming Landauer's Principle, constructing such
environmental encodings requires $(ln2) kT$ per encoded bit. For the observed
10$^{24}$ stars and a uniform binary encoding of center-of-mass positions into
voxels with a linear dimension of 5 km, the free energy required at the current
CMB temperature T = 2.7 K is $\sim$ 2.5 $\cdot$ 10$^{-27}$ kg $\cdot$ m$^{-3}$,
strikingly close to the observed value of $\Omega_{\Lambda} \rho_{c}$.
Decreasing the voxel size to $(l_{P})^{3}$ results in a free energy requirement
10$^{117}$ times larger.
