I am not a sociologist. But asking a counter question has to do more with logic, I think. You say that you are not a physicist (I claim that I am interested in physics, and hence doing some work in theoretical physics), but your questions are logical. I think the whole physics is based on logic. However, the present day physics has changed the meaning of logic (I think to suit the requirements) and says logic is not what you poor fellows think.

Regarding the straight line motion, I mean the actual word meaning of straight-line motion. (It is held that in a curved space-time, the motion of any body will be curved; it is logical provided there is an entity like space-time.) I think that in a three-dimensional space, bodies can move only three-dimensionally; I propose a helical motion for all bodies in the universe. Light is particles of matter moving along a helical path.
