From wikipedia http://www.google.com.au/url?sa=t&rct=j&...jbT7Xi65TQ
Specifically....
The age of the universe is about 13.75 billion years, but due to the expansion of space we are observing objects that were originally much closer but are now considerably farther away (as defined in terms of cosmological proper distance, which is equal to the comoving distance at the present time) than a static 13.75 billion light-years distance.[2] The diameter of the observable universe is estimated to be about 28 billion parsecs (93 billion light-years),[3] putting the edge of the observable universe at about 46–47 billion light-years away.[4][5]

If you're not supposed to ride faster than your guardian angel can fly then mine had better get a bloody SR-71.
