Everyone has been there... we are taught to think in terms of "things" moving in straight lines (distances) in an amount of clock time. In the RS, there are no "things," only
speeds, so you have to think of things like a contour map, but in 3D.
In this case, where the photon is λ, you have this speed relation: A ↔ λ →← B. The photon is progression (moving outward) from A, and gravitating (moving inward) towards B. And notice I used an arrow with two heads... not a vector, but an outward "push" from between A and the photon, and an inward "pull" between B and the photon. There is no translational motion here.
What is important to remember here is that A and B are VASTLY DIFFERENT SIZES. A photon is emitted from an ATOM, which has a gravitational limit of a few angstroms. Once the photon is past that limit, it is progressing away from the atom (A) and on its own. A and B are both within the gravitational limit of a larger object, like the Earth, so the "inward motion" of the Earth becomes the ruling factor, and tries to pull the emitted photon towards itself. Object B adds a bit to the Earth's inward pull, so the photon crashes into it when it gets near enough and you "see" it.
The RS is all about pushes and pulls... scalar motion--changes in scale that we observe as outward (expansive) and inward (contractive). Our minds construct a 3D, coordinate model on those motions, to give the appearance of things moving in straight lines over an amount of clock time. (There is a post in the Models forum where Zuoqian and I discuss how to transform scalar motion to a coordinate system, if you are a programmer).
As I have found over the years, it's not about
learning the RS... it is about
unlearning what you have been told is the truth, to give your mind the freedom to determine, for itself, what is going on.
