Question
Can you tell me if a universe is as same as a galaxy.

Thak you

Answer
No, the universe is different from a galaxy. Think of our human society. The galaxies are like individuals. The universe is like the whole society on the Earth. The whole universe is composed by billions of galaxies. The Milky Way is a small galaxy.
