To measure small things you need comparably short wavelengths. If you
make a photon with a wavelength so short it can measure the Planck
length it will have so much mass-energy that it will fold spacetime
around it and become a black hole...so you won't be able to use it to
measure anything.

What is the argument for the claim that we cannot, in principle,
measure any length smaller than Planck length? TIA, AG
