Hi all,
I've just been having an interesting pub conversation with (what I would call) an amateur cosmologist and I posed the following question "the observable universe is stated as being c 50 billion light years wide but (even putting aside issues such as expansion / contraction) if nothing can travel faster than the speed of light and the age of the universe is c 13.7bn years old how is this possible"? Between us we were stumped but I'd really appreciate any explanations of this.
Cheers, Pete.
