You have been contradicting yourself!
You agreed that the domain of applicability of SR is limited
to 'inertial' frames.

Please pay attention to what I actually said. What I said is that
there are many frames that are not *absolutely* inertial, but in which
the non-inertial effects are much smaller than the effect being
measured and are therefore negligible (where "negligible" literally
means "can be neglected").

Iow, you agree with what I wote:

"Claiming that nothing changes physically when the Earth moves
wrt the plane is wrong, because the Earth is gravitationally
linked with the Sun (neglecting the Galaxy, and even the whole
Universe), and you should know that SR cannot be applied
in gravitational fields."

No, I don't agree with it. Please read what I wrote about the
equivalence principle, which is one of the underlying bases of GR.

I wrote: "you should know that SR cannot be applied

to GR! Does that imply that SR also applies (nothing
coming from SRists can surprise me, even bad faith)!

Please pay attention. I told you where to re-read. Since you are
incapable of doing that, I will repeat myself.

One of the backbone principles of GR is that any sufficiently small
laboratory in free-fall (that is, IN A GRAVITATIONAL FIELD) is
indistinguishable from an inertial frame of reference. So, yes,
special relativity can be applied even where there is a gravitational
field as long as the tidal effects due to gravity are much smaller
than the other effects (including ones predicted by special
relativity) being measured. Furthermore, you made the earlier
incorrect statement that special relativity cannot be used where there
is acceleration. That is also incorrect.


Let's settle this first before continuing.
