Velocity Effect continued...
- A velocity away from the transmitter causes the observer to receive a later time signal than that received by a "stationary" observer (who is co-located when the time signals are received).
We referred to this as the "velocity effect", which we shall denote with the symbol o:
o = (s2 - s1) = v(t2 - t1) (where s1 and s2 are measured in light seconds, and v is measured in light seconds per second). Or:
o = (s2 - s1)/c = v(t2 - t1)/c (where s1, s2 and v are in SI units).
A New Concept
The problem illustrated in the thought experiment is that, under this scenario, two or more observers can receive different time signals from a distant transmitter, even though they are adjacent at that moment. Furthermore, when the experiment is re-run and the observers swap places, they still receive the time signals related to their own relationship to the transmitter. If you regard space as a physical entity, and light as photons or waves travelling through that space, then this "velocity effect" is impossible. It simply could not happen. Furthermore, unlike the Lorentz transformation, the relationship is linear, This suggests that we need a different conceptual explanation of the phenomenon. The scenario I wish to propose focuses on two classes of entities:
- Massless entities that can travel at the speed of light, and whose velocity is unaffected by the relative velocity of the source and the observer. For brevity I refer specifically to photons.
- Macro objects ranging from sand grains to planets that have mass, cannot travel at the speed of light, and whose velocity is affected by the relative velocity of the source (if any) and the observer. For brevity I refer to "macro objects".
