The theory that predicts there is a shortest measured interval assumes a
continuum. There's no logical contradiction is this. But physicists
tend to have a positivist attitude and think that a theory that assumes
things, like arbitrarily short intervals, might be better expressed and
simpler in some way that avoids those assumptions. This attitude does
not assume the mathematics itself is the reality, but only a description
of reality; so there can be different descriptions of the same reality.
