[QUOTE="1hot281, post: 11581311, member: 88586"] No, the universe is, according to all leading theories, 14 billion years old. But that doesn't limit the SIZE of the universe to 14 billion light years. The early Universe after the big bang expanded faster than the speed of light.[I] (Parts of the universe today are still expanding faster than the speed of light. Which is observable, but I'm getting off topic)[/I] So it's more than likely quite a bit larger than 14 billion light years. We just don't know how much larger it is... The observable universe is probably one patch of a much larger unobservable universe. There are parts of the universe which cannot be seen because the light/energy/information cannot reach us yet. These parts of the universe are outside our current cosmological horizon. But 1 billion years from now, our horizon will move out another billion lightyears. I think Dr Tyson explained it better: [/QUOTE]
