# Uncertainty principle fundamental or not? [duplicate]

The Heisenberg uncertainty principal says we cannot currently precisely measure position and momentum of a particle. So in principle and one day if we figure out how, or have more better sensitive technology, we could. How will this change quantum mechnics? It seems to me we would need to rewrite all of it since this principle is fundamental?

• The laws of arithmetic say we cannot have an odd number that's divisible by 2. So in principle, if one day we develop better technology to produce such numbers, how will this change arithmetic? – WillO Oct 5 '20 at 9:49
