Let me preface this by saying Math is not my strongest subject. I am curious if there is any relationship between proportionality and the term infinity. This question stems from an online discussion about whether or not the physical universe is infinite or not. (Obviously its not, but I have a hard time explaining this to the new agers). Lets say that on average, for every 100 stars in the universe, there is a corresponding black hole giving us a 100:1 ratio. Now lets say that the universe is infinite. Meaning there would be an infinite number of stars and black holes. Could you then say there is an infinite number of stars and black holes at a proportion of 100:1? I know how non-sensical that sounds, even to a math layman such as myself. But is there anything in the mathematics of infinity that has to do with proportionality? Could you describe the rate at which numbers appear, that are divisible by 2 versus the rate at which numbers appear that are divisible by 3 on an infinite number line? Thanks in advance!
