Equation 15
It may seem odd that whilst the ‘enhanced’ Planck length and Planck time set a lower limit for quantum particles, (see equation 14) whilst a similarly ‘reduced’ Planck mass sets an upper limit for the size of stable quanta.
However, the wavelength of a quantum is inversely proportional to its mass, heavier quanta have smaller not larger wavelengths.
Stable quanta cannot have a mass in excess of e-20 Planck mass or their wavelengths would fall below the pixilation level of the universe.
