If you can't measure it, the Heisenberg Uncertainty Principle doesn't
even apply! HUP tells you that you cannot MEASURE both position and
momentum at the same time to more than a certain accuracy.  It does NOT
put restrictions on the actual accuracy of either position or momentum
beyond that.  For example, in trying to determine whether an electron is
really point-like, we've measured its diameter to within 10^-19 meters, a
really really small number.  Maybe even smaller than this by now.  This
doesn't violate HUP as any attempt to measure its momentum at the same
time would result in a rather large number.
