The (real) interval [0, 1] consists of more points than just > 9182024 (or 9182024 +1). Of course. However, we can gain any finite granularity we want to simply because it is infinitely dense to being with. :^) Think of the granularity between the naturals and the unit fractions. Then the reals that are infinitely dense. They are uncountable because they are so dense. > > Actually, of (uncountably) infinitely many points. > > Hint: WM -this fucking asshole full of shit- is always talking nonsense. >
