He said that about his sequence and his intervals. Infinitely many of them

The intervals J(n) = [n - 1/10, n + 1/10] cover the relative measure 1/5 of ℝ+. By translating them to match Cantor's intervals they cover ℝ+ infinitely often. This is impossible. Therefore set theorists must discard geometry.
 The intervals J(n) are what they are. Translated intervals are not the same
intervals. The properties of the translated set depend on how you translate.
No. Covering by intervals is completely independent of their individuality and therefore of their order. Therefore you can either believe in set theory or in geometry. Both contradict each other.

For example, if you translate them to J'(n) = (n/100 - 1/10, n/100 + 1/10)
then the translated intervals J'(n) wholly cover the postive side of the
real line.
By shuffling the same set of intervals which do not cover ℝ+ in the initial configuration, it is impossible to cover more. That's geometry.
