For the record, here's what triggered all this...
>Even unmoving two portals at a 45 relative to each other should change how far 'equidistant' objects appear. Because the ones going in at the closest edge are literally making a shorter trip than the ones going in at the farther one.
>You really gonna tell me violet in picrel is the same distance as green?
With pic related.
Note how it doesn't even indicate rotation in any way? Note how it doesn't use red and green but rather purple? Note how the post itself makes explicit mention of UNmoving portals and rather asserts that it is the ANGLE that is relevant? My response >>15270281 is merely intended to show what a straight line actually looks like at an angle.

But it was too late. People started imagining propellers. They started insisting it was "obviously" moving this or that way, which gave rise to these >>15269978 >>15269980 competing interpretations. And of course "obviously" the top line actually had to be red, that was so "obvious" it went without saying. Why, someone had even drawn a helpful diagram that showed it "turning": >>15270281, see! None of the criticism raised here >>15270080 were ever even acknowledged. A beam of light is just like a guitar string, see, "obviously" (they got that one backwards too).

And then if you say
>I get the whole redshift/blueshift thing, but why are you people so desperate to pretend this shitty diagram is showing something insightful when you have to make numerous alterations to make it say anything on the subject at all?
They look at you like you got two heads. I'm starting to think I'm the only person in this whole debacle who wasn't trolling.

You are a dipshit desu. He's making a point about arrival times with moving/rotating apertures, and you are just ignoring it. Even unmoving two portals at a 45 relative to each other should change how far 'equidistant' objects appear. Because the ones going in at the closest edge are literally making a shorter trip than the ones going in at the farther one.

You really gonna tell me violet in picrel is the same distance as green?
