Please enjoy the privilege of belonging to the first generation of mankind being able to observe the entire visible universe and to draw cosmological conclusions fully based on observational facts. Julien Lesgourgues Currently there seems to be no fundamental physical or technological boundary that prohibits a further increase of sensitivity of astronomical obeservations. It is a matter of how much sensitivity our society is willing to afford. C.W.
