I think photons could have a mass - but then again, since they travel at the speed of light, they should be massless. Thus, you could have an argument either way for a velocity.

Then if you think about it, light has a primary velocity (speed plus a first direction). What gravity is doing near a black hole is merely causing light to speed up in a second direction. This second velocity would be a mere fraction of the original speed. But one could argue that the original velocity of light never really changes due to gravity.

Then how do we explain something like this article then: Link
