## Main Question or Discussion Point

(question inspired by a thread on the cosmology subforum)

Is there an intuitively simple theoretical reason for the existence of elementary units of charge but not of mass?

The parallels between Gauss's law for EM and gravity, the inverse-square law for both, the fact that energy is quantized, like charge is, and that there are elementary particles seem to lead to the notion of the existence of an elementary mass unit.

Is a matter of its smallness in case it existed and teherefore difficulty to be experimentally verified, like the suspected planckian length unit(mass is sometimes expressed in terms of length)? But that seems to imply the fundamental discreteness of our universe wich is far from being clear as of now.
