Question 4How does the traditional theory of the formation of the galaxy explain the origin of globular clusters?
a. They formed in the disk and later were ejected to the halo.
b. They formed in other galaxies and were captured by close interactions.
c. They build over time from the collision of stars in the halo.
d. They formed early on during the free-fall collapse of the proto-galactic material.
