Homework Help: New Hubble Constant

  1. Aug 7, 2006 #1
    Just got through reading http://www.space.com/scienceastronomy/060807_mm_huble_revise.html" [Broken] about findings that suggest the Hubble constant is about 15% smaller than previously believed. From the article:

    The new finding implies that the universe is. . . about 15.8 billion years old and about 180 billion light-years wide.

    My question is this: How does the universe get 180 billion light years wide in only 16 billion years without having matter travel faster than light? I'm sure there's a sensical explanation, I just have no idea what it is.

    P.S. Sorry if I'm posting in the wrong forum. Wasn't sure if I should post here or in the Other Sciences (i.e. astronomy) forum.
