While there is no SEQUENCE of uncountably may nested intervals, which
the very definition of sequence prohibits, there are certainly SETS of
uncountably many nested intervals.

EXAMPLE: For each real x in (0,1), [x, 2-x] is closed real interval and
the set of such intervals is both nested and uncountable.
But it is not a SEQUENCE of intervals.

So that what Ross thought was a paradox is just a kink in his thinker.
