Galaxies in Clusters -- the New York Cities of the Universe

After a very brief introduction to galaxies and galaxy clusters, I will talk about what happens to galaxies in such a crowded environment. That person walking through the crowded subway and jostling everyone? Happens to galaxies. That person who bumps into you running down the sidewalk so you drop your groceries? Happens to galaxies. How you have to grab on and hold tight to stay together in Times Square? Galaxies do too. How when it rains, you may not hit anyone, but your umbrella constantly gets snagged by other umbrellas? Even this, in a way, happens to galaxies.
