  In this paper we provide some circumstantial evidence for a holographic
duality between bubble nucleation in an eternally inflating universe and a
Euclidean conformal field theory. The holographic correspondence (which is
different than Strominger's dS/CFT duality) relates the decay of
(3+1)-dimensional de Sitter space to a two-dimensional CFT. It is not
associated with pure de Sitter space, but rather with Coleman-De Luccia bubble
nucleation. Alternatively, it can be thought of as a holographic description of
the open, infinite, FRW cosmology that results from such a bubble. The
conjectured holographic representation is of a new type that combines
holography with the Wheeler-DeWitt formalism to produce a Wheeler-DeWitt theory
that lives on the spatial boundary of a k=-1 FRW cosmology. We also argue for a
more ambitious interpretation of the Wheeler-DeWitt CFT as a holographic dual
of the entire Landscape.
