Age of Cosmos/Size of Cosmos?

  1. Sep 24, 2007 #1
    Hello Everyone,

    I'm a new member to this interesting forum, just joined.

    I was watching a program on the Discovery channel about the Universe. They were talking about the size and said it was "157 billion light years across. I watched the program 2 times to make sure I got it right.


    If the universe is about 13.7 billion years old, how can this be?
