“…43 See for instance de Haro (2017) for more details about the notion of duality in the context of the AdS/CFT correspondence. All metaphysical questions, for instance whether the AdS side and the CFT side represent metaphysically distinct possible worlds or not will be set aside since both worldsby definition of the notion of duality-would be empirically indistinguishable (see Read (2016) and Le Bihan and Read (2018) for an overview of these metaphysical questions).…”

Must a theory of quantum gravity have some truth to it if it can recover general relativity in some limit of the theory? This paper answers this question in the negative by indicating that general relativity is multiply realizable in quantum gravity. The argument is inspired by spacetime functionalism -multiple realizability being a central tenet of functionalism -and proceeds via three case studies: induced gravity, thermodynamic gravity, and entanglement gravity. In these, general relativity in the form of the Einstein field equations can be recovered from elements that are either manifestly multiply realizable or at least of the generic nature that is suggestive of functions.If general relativity, as argued here, can inherit this multiple realizability, then a theory of quantum gravity can recover general relativity while being completely wrong about the posited microstructure. As a consequence, the recovery of general relativity cannot serve as the ultimate arbiter that decides which theory of quantum gravity that is worthy of pursuit, even though it is of course not irrelevant either qua quantum gravity. Thus, the recovery of general relativity in string theory, for instance, does not guarantee that the stringy account of the world is on the right track; despite sentiments to the contrary among string theorists.

“…Also note that Matsubara (2013) and Read (2014) T-duals agree on the physical world or they do not. If they do, then for the purposes of this enquiry they say the same, all in; we will not be interested in alleged non-physical differences.…”

Theoretical equivalence and duality are two closely related notions: but their interconnection has so far not been well understood. In this paper I explicate the contribution of a recent schema for duality to discussions of theoretical equivalence. I argue that duality suggests a construal of theoretical equivalence in the physical sciences. The construal is in terms of the isomorphism of models, as defined by the Schema. This construal entails interpretative constraints that should be useful for theoretical equivalence more generally. I illustrate the construal in various formulations of Maxwell's electromagnetic theory. 2 The Schema as a Proposal for Theoretical Equivalence I first present, in Section 2.1, the Schema for theories and duality: from De Haro (2016: §1.1- §1.2) and De Haro and Butterfield (2017: §2.2- §2.3). Section 2.2 contains the proposal for theoretical equivalence, based on this Schema. Section 2.3 contrasts the notions of theoretical equivalence and physical equivalence. 5
