The Planck length may not limit quantization, but it is a hard limit on measurement. Due to Heisenberg uncertainty, a photon that with a position small enough to do the measurement has a momentum so large the photon would collapse into a black hole (which would immediately evaporate).
- furgooswft13 8y agoI don't think this is right. Measuring a photons position to the plank length or below (probably not possible) would just mean the photon has a very large uncertainty in momentum. But that's no different than saying if you take a single slice of a 44.1khz PWM data stream you'd have 100% certainty of amplitude and 100% uncertainty of frequency.
