May 12, 2018 at 21:32 comment added Brondahl ah, right, yes Cardinality as in Countability, as in (0,1) is indistinguishable from (0,1000) and also from (3,$\infty$). I was indeed being very dense.
May 12, 2018 at 18:28 comment added Vladimir Reshetnikov @Brondahl You can split $\mathbb R^+$ at any positive number, and will get 2 parts (a line segment and a ray) both of the cardinality $\mathfrak c = 2^{\aleph_0}$.
