Hi. Went to a lecture by Brian Greene a few days ago. He started his talk by discussing the logical consequences of the universe being infinite. But I'm really puzzled: the universe has been expanding at various rates - all finite even when very large - for a finite length of time (13.7 billion years) so how can the sum of {finite rates} * (finite time = 13.7 billion years) be infinite? Perhaps an infinite number of big bangs? Anyone got any information or ideas about this?
