: : If energy or e-m waves travel at the speed of light, is it also suspended in time? I know photons have zero mass, does this mean it does not follow special relativity's rules, thus goes through time as well? or does it behave differently because it is a boson (ie. no exclusion principle).

: : Is there and analagous way of explaining attractive forces (exchange of gravitons)?. I've heard the repulsive forces explained via recoil, which makes sense.

: photons have zero mass at rest

::(daViper) Hmmm. That forces me to ask two questions myself.

If you are implying that photons do not have zero mass when in motion, where does the mass come from as a result of this motion?

If the universe is expanding, can anything, including a photon, ever be said to be "at rest"?
