Description
Motivated by analogies with the electrodynamics of media, we propose a non-local extension of Einstein’s theory of gravitation formulated within the framework of teleparallel gravity. Employing a specific localizing kernel, we analyze the local limit of the theory at both the background and linear perturbation levels, and confront it with cosmological observations. We demonstrate that the model is capable of alleviating the Hubble tension.
