Since Einstein proved his theory of relativity by the bending of light though space-time,

and,

since Hubbel proved that the speed of light is constant (methods are another topic but let's assume it's fakt)

Doesn't it follow that light has mass since it curves along the gravitational forces?

 

If light did not have mass, would it not just continue into space without bending? Disregarding the gravitational effects on space-time?

>Photons (light) only has mass when it is moving.

Sounds dumb at first, but I'm trying the logic.

 

If weight has weight on earth and isn't moving, it still has weight, but it is moving (accelerating) toward the center of the earth.

 

In space, no movementโ€ฆ no weight. No weight, no mass.

 

I see the logic, but light cannot idle, it moves BECAUSE it has weight. The vacuum of space PROVES this does it not? An asteroid can sit motionion-less in the vastness of space, but can a beam of light do the same?
