  In this paper, we construct the wedge holography for the de-Sitter space as a
bulk theory. First, we discuss a more general mathematical construction of
wedge holography in parallel with wedge holography construction for the AdS
bulk, and then we construct the wedge holography in the extended static patch.
In the first case, we prove that one can construct wedge holography for the
de-Sitter bulk for the static patch as well as global coordinate metric on
end-of-the-world branes. Extended static patch wedge holography is constructed
by joining the two copies of double holography in DS/dS correspondence. We find
that wedge holography with extended static patch metric leads to the emergence
of communicating universes. Further, we propose a model which provides the
theoretical evidence of communicating multiverses.
