In the latest edition of Space.com newsletter it states that the currently accepted age of the universe is 13.7 billion years old and its width is 156 billion light years. Assuming that the big bang happened at what is now the centre of the current universe and that matter (or even radiation) cannot travel faster than the speed of light, how is the universe so big? Surely its width could not be more than 27.4 billion light years? Or am I missing something here?
