Q 1)Briefly describe why a differential rotation of gas or stars
in a disk galaxy will cause the winding problem of spiral arms.
Q 2)Spiral galaxies that we observed do not have winding arms.
This can be explained using a combination of Kinematic
Arms Theory and Density
Wave Theory. Use words AND equations to describe
clearly how these two theories solve the winding problem to create
spiral arms that do not wind and last through the age of the
Universe.
