Question

How was galaxy made​

Answer 1

Astronomers aren't certain exactly how galaxies formed. After the Big Bang, space was made up almost entirely of hydrogen and helium. Some astronomers think that gravity pulled dust and gas together to form individual stars, and those stars drew closer together into collections that ultimately became galaxies.

Following the big bang, the primordial universe consisted of only radiation and subatomic particles. Scientists have two kinds of theories, both of which hinge on the gravitational effects of collapsing gas in the early galaxy.
