Description
I will review the Hubble tension and its current status, before discussing five brief recent lessons which can be summarized as follows: 1) pre-recombination new physics alone is not sufficient to solve the tension; 2) constructing a successful model of pre-plus-post-recombination new physics is difficult; 3) Omega_m and omega_c play a key role in the discussion; 4) local structure can make the tension even worse; 5) the overall picture is not significantly changed by the latest DESI data.
