We point out that gravity on dS_n gives rise to a localized graviton ondS_{n-1}. This way one can derive a recursion relation for the entropy of dSspaces, which might have interesting implications for dS holography. In thesame spirit we study domain walls interpolating between dS spaces withdifferent cosmological constant. Our observation gives an easy way to calculatewhat fraction of the total entropy can be accessed by an observer stuck on thebubble wall.Comment: 10 pages, Latex; v2: references adde
