TY  - JOUR
AB  - We investigate how a Higgs mechanism could be responsible for theemergence of gravity in extensions of Einstein theory. In this scenario, at highenergies, symmetry restoration could “turn off” gravity, with dramatic implicationsfor cosmology and quantum gravity. The sense in which gravity is muted dependson the details of the implementation. In the most extreme case gravity’s dynamicaldegrees of freedom would only be unleashed after the Higgs field acquires a non-trivialvacuum expectation value, with gravity reduced to a topological field theory in thesymmetric phase. We might also identify the Higgs and the Brans-Dicke fields in sucha way that in the unbroken phase Newton’s constant vanishes, decoupling matter andgravity. We discuss the broad implications of these scenarios.
