A transverse wave (as you seem to think light is a wave in a medium) doesn't
involve anything actually moving in the direction of propagation. So I'm
not sure if that makes Newton's first law relevant.

If there is such a medium.

Research is always a good idea

I want everyone to notice that *INERTIAL* so far refused to answer the
question.

What is the distance between C and D, at the moment [T1] when [C is
adjacent to A] and [B is adjacent to D].

The clocks at A and B shows same timing for C respective D, but
inertial seems to think that the distance between A and B have some
special properties within C and D. So come on inertial tell us the
distance between C and D at [T1]?

Or have you chickened out?

I did answer. But not in the earlier reply you are dishonestly quoting now.

My answer was that there is *NO* moment T1 as you describe, when both C is
adjacent to A and D is adjacent to B (in system A and B, or in system C and
D).

There is a time moment what C is adjacent to A, and another when D is
adjacent to B.

I also told you the distance between C and D in the A and B system is approx
4.24km

The distance between A and B in the C and D system is also approx 4.24km

Of course not .. why would I be afraid of you? I answered you already. And

Actually the reply above already had the answer .. 4.24 km. But it came
BEFORE you answered the question about [T1] that I had already answered in
another subsequent reply
