### -Many paradoxes involving infinity arise from intermixing intensive
and extensive metrics. (*--*)

-Certainly an extensive metric of these infinite sets gets no grip on the
problem of the Collatz conjecture.

-Presumably, use of an intensive metric (i.e. density, a rational)
will do better.

- Two or three
*such* paradoxes were encountered in this work and resolved by applying
density as a measure.

-Much work revealing problems in infinite sets (e.g.
Cantor's
dust, a set of zero measure but
infinite content) is seated within the continuum of the number line.

-But the Collatz conjecture involves only **integers**, thus
avoiding this trap involving "measure".

-The assertion that the predecessor tree contains all the odd
integers on the basis of infinite summations of their densities (which gives 1/2)
is grounded in the density measure.

-Summation of the densities of the powers-of-2 multiples of all the odds
in the predecessor tree gives 1/2 also.
