do inertial reference frames exist?

anonymous · Answer

I think this is one of those things where you have to say 'locally' inertial reference frames, because it wouldn't apply at distances where the expanding universe would need to be taken into consideration.

yeah in a local domain the transformations are sound.

Is there such transformations that will be correct for galactic scales,
would these transformations resolve issues with dark matter,
