Yeah, the size of the universe is interesting from a purely academic standpoint but isn't it meaningless? I mean it's still the whole universe, right? Although toward the end of the article we have the implication that it WASN'T the entire universe - just what we can observe. So there may have been volume beyond the soccer ball. And if there was, does it matter? Does it affect our universe initial conditions?. And what's up with the superluminal expansion? And not just a little superluminal - it makes the USS Enterprise look like a slacker. At what point did the speed of light limit kick in and why? What changed? Something just doesn't make much sense. Can universal laws just change? Obviously they did - superluminal expansion wasn't just a feature, it was a necessity since density at that point had to make your run of the mill black hole look like a dense fog. So escape velocity was way over light speed. This implies things were weird as hell.
