So, too, are the set of numbers between any 2 numbers of the real number line, which would be an uncountable infinite set. I realize that no one can "count" those numbers, just as no one can enumerate the number of past events, if, in fact, the Cosmos is without a beginning. I am just claiming that "actual infinities" of physical things may exist, just as they do in transfinite arithmetic. If space is infinitely divisible, and, time, too, then those are actual infinities of things; if not, then they are finite. You (and, Craig) seem to be conflating the act of enumerating a set with the intrinsic membership of that set! Again, what is the cardinality of the set of "future praises" in Heaven?! Don't say that it is a "potential infinite"; I am not asking you to count it! I am asking you what its cardinality is?! Now, if you are going to insist on sets on being "potentially infinite", then please define what the cardinality of a "potentially infinite set" is! And, then, answer the question as to if some potentially infinite sets are bigger than others.
So you have a set of numbers that do not represent anything? Then they are just numbers, that do not correspond to the two points in any way.
And what you are describing is a potential infinite, because per your wikipedia page
Quote:This is contrasted with potential infinity, in which a non-terminating process (such as "add 1 to the previous number") produces an unending "infinite" sequence of results, but each individual result is finite and is achieved in a finite number of steps.
Do you agree, that even if you can potentially divide something infinity, that your results each time are a finite number?
No, I am saying that the sum of those finite numbers (their ordinality) is infinite. But, once again, please answer my question, "Are some potential infinities bigger than others?"
