I understand it has no rest math. But where does the mass come from?
There has to be mass to exert pressure. Does the mass just appear from
nowhere? I doubt it...

Another question... when subatomic particles are created in pairs from
energy, where does the mass come from?


I have no idea - which is why I'm asking these questions.

Maybe you need to learn more about mass in general, including rest
mass... a quote from wikipedia page on the Higgs Boson.

http://en.wikipedia.org/wiki/Higgs_b...entific_impact

"about 99% of the mass of baryons (composite particles such as the
proton and neutron) is due instead to the kinetic energy of quarks and
to the energies of (massless) gluons of the strong interaction inside
the baryons."

Photons are not alone nor especially unique.
