1.The Milky Way is a barred spiral galaxy, with four man spiral arms named Perseus, Cygnus, Centaurus, and Sagittarius. 2.Galaxies are organized and distributed into subgroups within the universe 3.Gravity is very important within our universe because, it is what holds together our galaxies 4.Galaxies vary in shapes, sizes, types and number of stars they contain 5.The force of gravity and dark matter shape and contort galaxies ultimately deciding their form Critical thinking
1.Galaxies are in a constant state of change. Due to the massive sizes involved and distances it is difficult to see the change in a single lifetime.
2. proposed that matter started out in these “smaller” clumps (mass on the order of globular clusters), and then
