We have recently measured a coherent bulk scale flow that encompasses~300 Mpc/h of amplitude 600-1000 km/s in the direction of the cosmic CMB dipole.
This bulk flow motion is very difficult to accomodate within the standard Lambda-CDM cosmological model. We shall summarize the results and its implications for cosmology, discussing possible explanations such as large scale voids and residual superhorizon fluctuations and their implications for inflation and/or quantum cosmology.
