Description

The SH0ES collaboration now has a 5 sigma discrepancy with Planck-LCDM and a H0 determination of H0 = 73 \pm 1 km/s/Mpc. This is consistent with the expected maximum in any FLRW cosmology, H0 \sim 71 \pm 1 km/s/Mpc. However, it should be stressed that the latter is an upper bound. One logical possibility is that the Universe is not FLRW and I will document a number of recent observations that may be pointing us beyond FLRW.
