light bent in gravitational field..
i am new to GTR. Mytext book use an example to show ligt bendinf.
when a light release from the back of the rocket which goes around the earth, since the rocket is in free fall, light would not bent relative to the rocket, but bent relative to earth.
my problem is, is that means the amount of bending depend on the speed of the rocket?
if the rocket is very fast, than light would travel greater distance relative the earth, so there more bending?
If there is no rocket, but just a light source above the earth, would it bent at all?

It would indeed be a problem if two geodesics, initially tangent at a given point in spacetime, later diverged. But that isn't the case here.
