Recent insights from black hole physics, string theory and the AdS/CFT correspondence suggest that gravity is an emergent phenomenon. The microscopic counting of black hole states together with the recently found connection between gravity and quantum entanglement give important clues towards the underlying mechanism. Motivated by these ideas I propose that space-time can be viewed as an entanglement network of “long strings”. Anti-de Sitter and de Sitter space correspond to the distinct situations in which these “long strings” are all in their ground state or all in an excited state. By using an analogy with entanglement networks of polymers, I show that this description leads to memory effects that quantitatively describe the observed phenomena attributed to dark matter.
