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 sourcedata from the European Planck satellite. “Compared to the previous best performance measurements, 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 growing expandinga 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 strength gravityto pull things around.” The Planck satellite maps the cosmic microwave background, the faint after glow of the big bang. And that lets divertcosmologists look back to the very dawn of the universe.” The variations from place to place in the map that Planck has made tell us new things about what emergedhappenedjust 10 nano-nano-nano-nanoseconds after the big bang when, in a gazillion times less time than it takes me to say this, the universe grewexpanded by 100 trillion trillion times.” It’s been said that ” the universe is not only stranger than we imagine, it is stranger than we can imagine.”
