Lab 2: Evolution of Cosmos and Life Exercise: Visualizing the Expansion of Space 1. Pick a galaxy to represent the Milky Way and match the overhead to the original. a. What direction are the other galaxies moving relative to the Milky Way? -The directions that the galaxies are moving are outwards and away from the Milky Way. It tends to stretch in all directions. b. Are all the galaxies moving at the same speed? - All of the galaxies are not moving at the same speed because some are moving faster than others. c. How does the velocity of nearby galaxies compare with that of galaxies further away? - The velocity of nearby galaxies compare with the galaxies further away in that it moves faster. 2. Pick another galaxy to represent the home of an alien civilization and redo question 1. a. The direction that the galaxies are moving is outwards again and it also stretches. b. All of the galaxies are not moving at the same speed because they differ in the way that some that are closer moves slower than those who are further away. c. The velocity compares in that it makes the galaxies move faster and seem further away
