do light particles have mass? because if they do then shouldn't theory of relativity apply to them? u know all that travelling at light speed jazz?? just an idle thought


banzu_o :confused:

No photons do not have mass. (They do have impulse.)

hey banzu_o

there is already a thread like this, in the astronomy, exobiology, and cosmology part...

it's called 'light has mass?'

Have fun!
