(a nice description of rest and relative mass. Thanks Chris.)

But now I would like to take this a few steps deeper. What mass do I
deal with when the object is a collection of confined photons, and
possibly some neutrinos. The rest mass of a confined photon should be
it's ordinary mass, or just it's energy, eh? The gravitational mass of a
star then is (a bunch of stuff) + (the mass of the confined photons).
When the confined photons go streaming off to infinity, they can leave
as much as all of their mass/energy behind. Where is it? How is it left
behind?
