: : 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"? Actually, what I was wondering about doesn't really have anything to do with the mass of a photon. Because when an object approaches the speed of light, time slows down for it (relatively), and when 'c' is reached, time would stop, mass becomes infinite etc. So, since light travels at 'c' does this mean time has stopped for it? It is said that ligth has zero rest mass, how can it have mass when it is moving. The mass of a moving photon is probably just it's energy equivalent(e=mc2). Is there anyone out there who can answer or clarify this? Where's that nate person, he/she seems to know alot about this stuff. |
