Light is rather slow. if you visualize a laser, mounted in one end of a
rigid tube, say, 1 light year long.

Turn on the laser, and at the same instant, rotate the rigid tube one
revolution in eight minutes, and then stop the rotation, keep the laser
on, or turn it off

Of course the light will have travelled 93,000,000 miles, in 8 minutes,
while the tube's opposite end will have travelled 1 light year, in
effect. by rotation.


This concept can be scaled up, or down,  and is easy to visualize, but
the effect, of rotation on the rigid tube, is always faster than the
linear velocity of light. 

It's instantaneous, in other words.  

Of course if you took 1 light year to rotate the rigid tube, the laser
light would reach the opposite end of the tube at the same time the
rotation is completed & so forth with different values of measure.
