Answer correctly and read the questions corretly, this is all one quesiton if done correclty and organized I will write a very nice review about you!
1. How did Edwin Hubble measure the distance to the Andromeda Galaxy?
He deduced it from its redshift.
He measured its parallax.
He used Cepheid variables in the Andromeda Galaxy.
He used white dwarf supernovae in the Andromeda Galaxy.
Part A
What was the distance between the points that would someday become, respectively, the center of the Milky
Way Galaxy and the center of the Virgo Cluster at the time of decoupling? (The present separation is 18
Mpc.)
