Preface of my understanding:
While galaxies may be moving, they are primary enacted upon by the expansion space.
while a galaxies standard motion accounts for some redshift, most redshift derives from the expansion of space.
Primary questions:
1. I am not entirely sure how space itself expanding impacts the frequeency of light, does it smear out light of the expanded area?
2. As space expands there is now more space TO expand therefore causing the acceleration we see. So can we observe the redshift of the most distant galaxies getting more and more red the further they get... if indeed the further they are the faster they go?(i.e. measure redshift today, come back next year and it's further redshifted?)
