Actually, I found what you wrote enlightening because it had this mindbending effect on me that I found interesting. It makes me think of some stuff that I hope doesn't reduce your question with something boring, and conversely, some stuff that doesn't assume I have an answer, riddled with inscrutable jargon. It's just more questions really.
All I was going to say was something obvious; that I have noticed that if I see a plane in local airspace, it seems to have cleared the area of space that is visible to me quicker than an aeroplane thousands of feet higher.
The plane farther away is travelling faster than the nearer one that recently took off from the local airport, but it appears to be getting from A to B more slowly relative to my position. I guess also, along with the spatial context thing, because the light that creates the visual impression of the more distant plane took longer to reach me it is a light impression coming from the past?
I am seeing a light impression that does not accurately reflect that plane's real time to its occupants. Like if I am seeing the plane and looking at my watch and it says 3 o'clock, but the actual light impression of the plane I am seeing if I could somehow see through the walls magnified like it is Wonder Woman's plane - and with a comic book style magnified cutaway at that - could see a passenger looking at their watch, and their watch had been synchronized with mine before they left, it would be fractionally before 3 o'clock? Is there such a thing as objective time, or is it a kind of fallacy, or a tool we use that only works in a relatively localized field?
This doesn't mean the passenger existed before me does it? I mean, I just saw them earlier on, when we synchronized our watches. It just means the impression I am seeing of the plane they are in happened before I saw it?
The plane that is higher has a lot more space to appear to travel across which adds to the contextual illusion that it appears slower, or, to take more time?
Faster-than-light ships seem to be able to control the speed at which they travel right across the range of the visible-to-the-naked-eye spectrum and then outside of that. I think Time, or rather, our perception of it, is localized. Does this have to mean this effect has anything to do with a big bang, or necessarily expansion?
Our perception of density and objects' relative distances alter radically the further away they are from us, and of course red shift is based on the fact that the tools we are using to see that far away are representing those light impressions to us in the infra red spectrum. So it is already sort of out of our normal frame of perceptual reference, as are radio galaxies I guess?
Nope. Can't answer your question, sorry. Enjoyed thinking about it though.
