wow, I'm amazed at the number of people who actually knew anything about cardinality..... Yes, they both have the same cardinality (the same infinite number of points)
But, not all infinite sets are the same size of infinity... some infinities are more than other infinities....
(this should cause some headaches among the non-math majors )
Oh, and again, .99999..... DOES = 1. I ought to offer a prize to anyone who can successfully prove otherwise. (rigorously prove mathematically.... Anyone who proves the opposite can get published in any leading mathematics journal and be world famous)
