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.)


I have already answered that question. As per Newton's laws of motion. If you like it is an axiom of physics that 'straight' is natural and a physical process is required to change it from that natural state.
