If you don't know what I was referring to, then why where you so sure that "it doesn't violate relativity" then? The statement was made about the infinite size of the Universe and the OP (along the way) was talking about the observable Universe. He is mixing the extent of the Universe with the spatial dimensions of the Universe (so, the better word here is actually space). It is still an open debate if the dimensions of the Universe (space) are infinite (although what we knows seems to point that way), but the extent of the Universe is not infinite, if it was, that would violate relativity (or the standard model as I explained along the thread).
