  The contemporary physics has revealed growing evidences that the emergence
can be applied to not only biology and condensed matter systems but also
gravity and spacetime. We observe that noncommutative spacetime necessarily
implies emergent spacetime if spacetime at microscopic scales should be viewed
as noncommutative. Since the emergent spacetime is a new fundamental paradigm
for quantum gravity, it is necessary to reexamine all the rationales to
introduce the multiverse hypothesis from the standpoint of emergent spacetime.
We argue that the emergent spacetime certainly opens a new perspective that may
cripple all the rationales to introduce the multiverse picture. Moreover the
emergent spacetime may rescue us from the doomsday of metastable multiverse as
quantum mechanics did from the catastrophic collapse of classical atoms.
