Can we measure structures to a precision better than the Planck length? (English) Zbl 1246.83077

Summary: 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.
