	The Assumption regarding the mass is incorrect in this case.  In
order to have any significant effect in intercepting photons in a
coherent
laser and still have enough mass left over to continue an effective
screen
over the large volume of space that we are talking about, would require
a
reasonably significant mass.  Therefore, it would take quite a bit of
energy
to keep this mass of swirling crystals to stay with the orginating
craft.
