by thinning the block nothing happens , unless the block becomes
smaller than the beam.

in which case the light entering the block is only less.


the problem with the experiment is that it is too small.

lets increase its size.

lets make it 93 million miles from the center of the centrifuge.

so that light from the center would take apx 8 minutes to reach the perimeter of the bowl.

like our suns light hitting the earth.

instead of using the sun we use a hand held laser.

and the laser is rotating , the light from the laser will
look as if it were bending if viewed from above.

lets reverse this , if we put the laser 93 million miles from the center of the bowl and point it at the center and let the laser orbit the center , it still takes apx 8 minutes for the laser light to reach the center.

looking at the laser beam from above the light will look as if its bending as it travels.

but all of the light is moving away from the center at a right angle to the center.

motion and time becomes involved.

like pointing directly at a moving target and trying to hit it
you will never hit the target.

if the space between the earth and the sun were made of glass
then the time would be greater than the 8 minutes because the glass would slow down the light waves.

which brings us back to the thickness in your first post.

does thickness of a medium matter?

on a sunny day is there light 1 mile down on the sea floor?

of course thickness matters.

light slowed down to the speed of a bicycle



now if the bose einstein condensate were rotating , the light
would exit the condensate at a different angle than it entered , it could even be sent backwards.
