Distances in Space Lab
Analysis:
1. The other galaxies are moving away from the Milky Way as the universe is expanding.
2. Scientist know that galaxies are moving away because of the red shift. Through a telescope, they see that the galaxies moving away have a lower frequency and are red.
3. Yes, somewhat but the only flaw is that the the dots closest to the opening did not move much and the dots farthest from the opening move a lot.
