Oh, I'm SO glad you said this. I think the same thing! In fact, it generalizes to other digits besides 9 as well! The case with 0 is particularly interesting. Clearly 0.000... is also a "never ending relation more than a specific location on the real number line." I mean, *obviously* it's different from 0. Look at all those additional digits on the end!
