yes that is the main problem!
photon mass is too small to be detrected by our existing tools but ....
we have in addition to it th elittle machine that is above our shoulders (:_)

a wonderful question ! why did you came with it so late ?(:-)
that is what my little machine above my shoudees tells me -: --
*that is may be the only way to reconcile between -photon has mass'
and the fact that it moves with the velocity of light!!
(thremendously simple !!!)
anyway 
who on earth enshured you that the gama factor (that was not invented by God
but human people) ensuored you that the limits of that gama factor
are limitless???!!!
did you ever heared a postulation that ANY
physical formula or equation  HAS ITS LIMITS ???
that is imho the diffeence between mathematics and PHYSICS
(even mathematical formulasha soften their limits !!)
the roll of the (unparrot) physicist is to ....
find those limits !!!

yes scince in spight its pompous pose (pompous people !)
while it deals with dead ends- is nothing but a trial and error system

i agree to anything above except your 'discredited'
  But you know this.

btw we ddint finish our discussion about iirc the(fucken (:-))
 electron shell theory
in most casses it is rather  the young people who are the  revolutionists
in my case it seems that  - i am the  'youngster'.....
all the best
