Try Google "big expansion" The baloon is a good example, but think of the Atoms of gas inside, and not the surface. each trying to get as far away from each other, while it gets bigger without adding anything. thats why we cant see futher away than 13b lj. It was too dense for light to travel and too hot for Atoms to condense. At least thats how i understand the latest models as Amateur...
