Query: Spacetime Equals Entanglement   We study the Hilbert space structure of classical spacetimes under the
assumption that entanglement in holographic theories determines semiclassical
geometry. We show that this simple assumption has profound implications; for
example, a superposition of classical spacetimes may lead to another classical
spacetime. Despite its unconventional nature, this picture admits the standard
interpretation of superpositions of well-defined semiclassical spacetimes in
the limit that the number of holographic degrees of freedom becomes large. We
illustrate these ideas using a model for the holographic theory of cosmological
spacetimes.
