Ask yourself this: what "physical process" keeps the light moving in a straight line?

I would suggest that if light moves in a straight line it is because of the ABSENCE of a physical process which would make it deviate.

What "physical process" makes it be _straight_?

(I am trying to get you to see just one of the many ASSUMPTIONS
you make without acknowledging them.)
