Thermal Origin of the Attractor-to-General-Relativity in Scalar-Tensor Gravity
Valerio Faraoni, Andrea Giusti
Abstract
The convergence of scalar-tensor gravity to general relativity, or the departure from it, is described in a new analogy with heat dissipation in a viscous fluid. This new thermal picture is applied to cosmology, shedding light on whether gravity deviates from general relativity early on and approaches it later in the cosmic history.
