Using the new terminology to describe the physics behind the constant speed of light: ( transmissions is not of seen light moving from place to place in the environment external to the observer but unseen Pre-light-binaries in observation independent reality.
Reason for the constant speed of ‘light’ in a vacuum
The Pre-Light binary(transmitted by electromagnetism) is only an existing/happening thing when it is formed within the environment, being in part a particular environmental disturbance. It is not a transmissible composite without it. Without a transmission means the particle component does not move to the receiver and cause the chemical changes allowing a seen product to be formed. The (as it seems) indivisible particles emitted and associated with seen light are not themselves alone the Pre-light binary necessary for the wave behaviour inferred from interference patterns observed in the outcomes of various experiments. They initiate the pre-light transmission process, and enable detection of it but are not sufficient themselves. The Pre-light binary exists until it is absorbed by a receiving material or object, when it ceases to be existing and happening.
The motion of the source prior to formation of the pre-light binary does not determine the speed of the Pre-light binary (speed of light) when it is in the environment. Likewise the speed of the receiver plays no part in the speed of the Pre-light’ binary after receipt as the Pre-light binary no longer exists. Only the travel in the environment between source material and sink material corresponds to existing of the Pre-light binary. The composition, constituents and concentration, of the environment determines the speed when not in a vacuum. When in a vacuum the speed is constant.
A material object, such as a ball, exists before it is released, and after catching. Taking on the speed of the carrying objects, which will be added or subtracted (depending on same or opposite direction of motion, from the speed of the ball would have if the carriers were stationary relative to the observer.
