You may want to include Frank Wilczek's insight (See Below). That is,

quarks and gluons. :-)

Most of the proton?s mass arises from the fact
that the quarks and gluons inside it are moving around quite
vigorously. Therefore they have a lot of energy. It is just that
energy, through the magic of m = E/c2, which accounts for most of your
mass.

Oooh, ouch.

That is NOT what Frank just said.
