Re: What composes the mass of an electron?

A definition of mass, as found in Google:
 
"Mass is a measurement of the amount of matter or substance in an
object.
It's the total amount of protons, neutrons, and electrons in an object."

So you have that wrong too. (can't you get anything right?)
You must add the kinetic energy (positive)
and subtract the binding energy, by E=mc^2.

It's "accepted" since the 60s that protons and neutrons are not
elementary particles anymore. As stated in the Standard Model of
Elementary Particles, protons and neutrons are composed of quarks, with
different flavors.

I know you are going to hate this,
but most of the mass of the proton is kinetic energy.
Being confined in a small volume the quarks
(and gluons) have large zero point energies.
In fact they are highly relativistic.
Quark rest mass is only a small part of the proton mass.

But electrons are thought as elementary particles, so they can't be
formed by a collection of other elementary particles. Even quarks are
currently thought as working together with elementary gluons (QCD, Gauge
Bossons).
 
So, what is THE MATTER that electrons contain?
 
This is one of many FAILS of the current SMEP.
 
Is that the electron's mass is composed of unknown matter? Maybe of
electromagnetic nature?

Nope, the electrons do not 'contain' mass,
they are massive.
For an explanation you need to wait for the theory of everything,
