ħello. Here is my question: Has the so-called "planck length" (~1.61622837 * 10^(-35) meters) been derived with mathematical rigor within standard quantum field theory? If so, I need help finding this proof. Any literature would be appreciated.(adsbygoogle = window.adsbygoogle || []).push({});

Also: If it has, then doesn't this imply a lowest delta-momentum, since momentum is the complex conjugate of length via Heisenberg Uncertainty principle?:

S(momentum) * S(location/"length") ≥ ħ/2
