All of oo?
Yes. All of the naturals are integers. Only half of all the integers are
naturals.
All of the points in (0,1] are in (0,2], but only half of all of the
points in (0,2] are in (0,1].
You are equating two quite different notions: smaller and half as large.
In case of two finite heaps of size a and b of numbers, a=b/2 implies a<b.
In case of a=oo and b=oo, we may have a=b/2 while a is not smaller than
b but simply not comparable: oo = oo/2.
