According to a story featured on Yahoo today, "Scientists now estimate the universe to be about 13.7 billion years old (a figure that has seemed firm since 2003, based on measurements of radiation leftover from the Big Bang) and about 156 billion light-years wide. The new finding implies that the universe is instead about 15.8 billion years old and about 180 billion light-years wide."
Surely the decimal point in this story is in the wrong place. How could the universe be more than 10 times as wide (in light years) as the age of the universe? Either they have the decimal point in the wrong place or the stars are travelling away from each other through space several times faster than the speed of light.
