(Late-time) “solutions” to H0 and S8 tensions through modified gravity.
We discuss some possible late-time alleviations of H0 and S8 tensions in the context of modified theories of gravity. In particular, we examine how torsional and non-metric theories can lead to weaker gravity at “intermediate” scales, in a suitable way in order to lead to faster expansion and less matter clustering (and we show why this is not possible in simple curvature-based modifications).
