I don't think the suggestion is that they arrived quicker, but rather they were emitted before the gamma burst. Whatever process...

An article on giant (or monster) stars came to my attention. Astronomers have been looking at system GS 3073 with the JWST. Too Much...

That still doesn't help, because the area that needs to be covered in the models being proposed can't be limited to just such areas...

Instead, looking for negligible tidal effects one would consider areas far away from gravitational centers like stars and galaxies...

So, if you say "that it (the equivalence principle) only applies locally, over a scale where spacetime curvature is negligible and an...

Such scales refer to Galaxy cluster which as I understand it don't feel isotropic expansion. If we consider them as spacetime patches...

You can, but many people have a hard time picturing how this is possible. My suggestion provides a way to picture this that was helpful...

Why can't one simply argue that in an infinite expanding universe the distance between any two comoving objects grows without limit?

Unexpectedly for me this seems a crucial point! PeterDonis and Ibix, many thanks for enlightening comments.
