In the last few years increased precision of experimental data led to challenges to ΛCDM. The dynamics of the expansion and the statistics of the growth of structure appear to be in tension between local measurements and inference from the CMB. I will discuss the H0 and S8 tensions and discuss new physics solutions in the context of dark matter/energy and quantum gravity.
