Hunh? This is certainly true, but on the other hand between any two rational
numbers there are also an infinite number of irrationals.

But even if this were not the case, the fact that any two rationals have
other rationals in between would not make Hal's claim of continuity true;
rather it would prove the opposite, discontinuity.

Seems to me we have here a demonstration that, as in physical reality,
continuity cannot exist. What could it possibly mean?
