Infinite sets do not need to have both ends in them.
Between 0 and 1 there are unit fractions. Hence there must be a first one. The interval without unit fractions and the interval containing unit fractions are separated by the smallest unit fraction.

Why?
That is just finite logic.
WHen we have an infinite set, both ends don't need to be there.
