Justaskin, I'm not too good with the higher maths either, but here's a good example of an infinity growing, or an infinity that is bigger than another infinity. You could have the set of all positive intergers {1,2,3,4,...∞} which goes on forever and ever to an infinity. If that then grew to all numbers with one decimal place you'd have {1.0,1.1,1.2,1.3,1.4,1.5,1.6,1.7,1.8,1.9,2.0,2.1,2.2,.............∞}. Both are infinities, but one is a bigger infinity, and I don't know exactly why but an infinity can get bigger. One explanation as to how it gets bigger is dark energy in space, which no one has pinned down yet. Anyway that's a quick example without any math I would be floundering in.
