Title: Is the Universe 27.4 billion light-years across?

Neli Espe asked the Naked Scientists:
   
Dear Ben and Naked Astronomy team, thank you for your superb work (http://www.thenakedscientists.com/astronomy).

I am passionate to learn more about this complex topic; I listen to podcasts from around the world, and you, by far, do the BEST job! You have made a great difference in my life.

I also have a question - How big is the observable universe? If I look in on direction, it is 13.7 billion light years, if I look in the opposite direction, isn't it also 13.7 light years. So, isn't it 27.4? And then adding all the accelerated expansion....

Thanks, Neli Espe, USA, Anacortes, Washington
