    Exactly! It is unintuitive, but there are as many infinite elements of the set of all real numbers between 0 and 1, as there are in the set between 0 and 100.

    I hope this demonstrates what the people here arguing for the paradox are saying, to the people who are arguing that one is obviously longer.

    Just because something is obvious, doesn’t make it true :)

      Alright, I concede. I did it wrong but still ended up with the right answer. There are other responses in this thread with correct explanation for why Asia has more coastline

        Yeah, if you use an arbitrary standardized measuring stick, the problem goes away, as it is no longer infinite.

        Still a fun thought experiment to demonstrate how unintuitive infinities are!

        Anyway, major kudos to you for engaging with this thread in good faith! That is so rare these days, I barely venture to comment anymore. Respect.

        … and thank you for the opportunity to share a weird math fact!

          Hmm I’ve consulted a mathematician that I know, and they say that cardinality isn’t really the same as “size”, but comparing the two infinite sets of the same cardinality is basically meaningless because infinity is not a “number”, even though one set is provably “bigger” than the other set
