Muons might be considered cute because they're small — like electrons and tau particles, they are considered to be point phenomena at the quantum level with no practical physical size (at or below {{w|Planck units#Planck length|subatomic Planck-scale}}), although ''possibly'' that (and the time they last) changes as a function of the quantum expander being applied to them. It might possibly also reference a certain way of pronouncing &amp;quot;muon&amp;quot;, which starts with a &amp;quot;mew&amp;quot; sound, which in turn is associated with kittens (and {{w|Mew (Pokémon)|a fairly cute Pokémon}}).&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
