There's no absolute frame refrence in physics. We're talking math theory here.

Light in an accelerating elevator is physics. Light in an anything is physics.

    The math that describes light in one reference frame is a mathematically perfect straight line. In a different reference frame the math that describes light is curved.

    Just like a straight line in one coordinate system can be transformed into a curved line in another system.

    You're just repeating yourself. It doesn't make you right.

    A straight line in a curved space that adheres to the curved space is still a curved line. An actual straight line exists between the two same points that is shorter than the path light would take. That is the mathematical minimum distance.
