Simon: Mom, there’s no number that’s close to infinity.
I: There isn’t, is there? But even when I realise it’s true, I have trouble imagining this.
Simon: This is the way I imagine it: if you collapse an infinite length into some non-zero finite number, then all the numbers should be infinitesimally close together. That is, infinitely close together but not the same.
