Tell me what is dark matter?
What exactly is dark matter?
Does Hubble's Law work well for galaxies in the Local Group (such as Andromeda)?
No, because dark energy is accelerating the universe's expansion over those distances.
No, because we do not know the precise value of Ho.
No, because Hubble did not know the Local Group existed when he discovered his law.
Yes, it works well for all galaxies.
No, because galaxies in the Local Group are bound gravitationally together.
