Description
We summarize the famous tensions between various observational
datasets and theoretical predictions of the Standard Model of Cosmology,
such as the H0 and S8 tensions, that could be a sign that we are
approaching New Physics. Then we provide possible solutions, arising
from modifications /extensions of the standard lore, focusing on
(late-time) modified gravity solutions. Finally, we show how
Gravitational-Wave and multi-messenger astronomy can be crucial in
distinguishing various classes of gravitational theories.
