I am curious why a more intimate relationship between light and empty space is not something one ever hears about when I think about the three obvious examples of why there seems to be a relationship. 1) Light follows a curve when in a curved spacetime (a gravitational field), 2) photons at large distances from us can move away from us at speeds exceeding c due to the expansion of space, and 3) inertia felt by acceleration and acceleration felt by rotation are absolute in nature which (it seems to me) must imply they are relative to some kind of physical spacetime structure.
What I'm asking is given these 3 examples, why isn't it acceptable to consider a strong relationship between light and space, a relationship that would allow for (and even explain) the constancy of the speed of light while still allowing for a structure that would help to explain the 3 examples given here. Isn't it possible to define a type of space that both upholds relativity but also can be pictured as something physical that can be stretched, moved, and spun to accommodate things like curving spacetime, expanding space, and a Newtonian type of absolute space? A theory to describe what such a space could physically consist of or be made of so it could be pictured? I'm sure I'm not the only one to have thought about this so is it just simply impossible or illogical?
