what i want to know is how much area of universe (in light years if possible) is surveyed by WMAP .when you say CMB permeates entire universe based on data from these satellites orbiting Earth how much of universe is actually surveyed by WMAP ?
* The analysis of the WMAP image of the sky, indicates that the universe is older than 13.7 billion years (with an accuracy of 1%), it is composed of 73% dark energy, 23% Cold dark matter, and only 4% of atoms. It is currently expanding at a rate of 71 km/s/Mpc (with an accuracy of 5%).Credit: WMAP Science Team, NASA
if you survey around where we are now in this universe you'd see more matter than anything else..so how physicist say all those quoted above
the farthest we seen of universe is with hubbles' Ultra deep field image / how can WMAP satellite detect the temperature of thermal radiation over HUDF with incredible accuracy
