Can we measure structures to a precision better than the Planck length?

TL;DR

This paper critically examines recent claims that the Planck length is not a fundamental limit to measurement precision, demonstrating that the argument does not substantiate such a conclusion.

Contribution

The authors analyze and refute the argument suggesting measurement precision can surpass the Planck length, clarifying the true implications of quantum gravity limits.

Findings

The claim that the Planck length is not a measurement limit is unsupported.

The analysis shows the original argument does not hold under scrutiny.

The paper clarifies the fundamental limits imposed by quantum gravity.

Abstract

It was recently claimed that the Planck length is not a limit to the precision by which we can measure distances, but that instead it is merely the Planck volume that limits the precision by which we can measure volumes. Here, we investigate this claim and show that the argument does not support the conclusion.
