The Microwave Anisotropy Probe
's long-awaited map
of the afterglow of the big bang
was released today, and all of a sudden, most of the uncertainty in the concordance model of cosmology has disappeared. We now know, to within 1%, that the universe is 13.7 billion years old. We now know that Hubble constant is 71, plus or minus 4. And though the results agreed stunningly well with the weird picture
that cosmologists have about the nature of the cosmos, there was one surprise -- the first stars were born way before expected. Great day for science, and a likely future Nobel.
