Universe

Our universe has long passed for a 13.7-billion-year-old, but it turns out it's really a bit more elderly. So says new [data:source] from the European Planck satellite. "Compared to the previous best [measurements:performance] , the universe is a little older, 13.8 billion years. "U.S. project scientist Charles Lawrence of NASA's Jet Propulsion Laboratory, in a March 21st press briefing. "It's [expanding:growing] a little more slowly. There's more matter, both the kind that we're made of that we can see and the dark kind that we can't see, but that has [gravity:strength] to pull things around." The Planck satellite maps the cosmic [microwave:microscope] background, the faint afterglow of the big bang.
