> moving apart from each other at something like 2,087,340 km/s. Surely that should mean that any light emitted from those two objects never reaches the other as this is well above the speed of light.
At first I was reminded of thought exercises with trains moving at 0.9C, but I think this much simpler: The velocity of the object emitting light doesn't matter once the light has been emitted. The formula just involves light moving at 1C and the receiving object moving at less than that.
(But take me with a grain of salt, I may be missing what you're getting at.)
