That's the thing, though -- it's not possible to know precisely enough. The more precisely you establish the location of an electron, say, the less precisely it is possible to simultaneously determine its momentum. That's what the
Heisenberg uncertainty principle is all about. It's why there was a good bit of resistance to the acceptance of quantum mechanics by "classical" physicists in the early-mid 20th century; the fact that we
can't measure everything. Not that we lack the tools or knowhow, it's not possible.
So you're talking a level that not only isn't possible by mankind's technology, its not possible in principle either.
