this is why sqrt(2) can not physically exist

in fact the natural numbers do not physically exist either, there is no '1' that i can hand you or manipulate. there are measurements such as 1 metre etc. but with this reasoning any real number x would physically exist by just taking a line of length y metres and coming up with a new measurement system (say 'netres') where 1 netre = y/x metres. then your physical line of length y metres is also a line of x netres, but this doesn't mean the real number x physically exists
