What is the difference between a universe and a galaxy?

Answer 1

The Universe is the whole thing, while a galaxy is only a part and there are billions of galaxies in the Universe.
universe consists of many galaxies
(astronomy) a collection of star systems; any of the billions of systems each having many stars and nebulae and dust is known as galaxy

Everything that exists anywhere is known as universe

ex:"they study the evolution of the universe"
A 'galaxy' is a collection of stars and planets in one space orbiting a core or a very large star. The 'universe' holds all these Galaxy's and could be infinite.

E.g. We live in one of millions of Galaxy's but all the Galaxy's live in one universe.

(the best way I can explain it in typing.)

Answer 2

A universe is the entire system of all matter and energy that exist, including galaxies, while a galaxy is a massive collection of stars, gas, dust, and dark matter held together by gravity. Galaxies are just one component of the universe, which contains all galaxies, stars, planets, and other cosmic entities.

Answer 3

The Universe Is the whole, where all the galaxies are, and galaxies are just big clusters of starts, planets and different types of debris.

Answer 4

The Universe contains the galaxy's which contain the solar systems which contain the planets and stars.

Answer 5

A galaxy is made up of solar systems and a solar system is just a part of a galaxy. Our solar system is just a dot in the Milky Way galaxy.

Answer 6

The Universe is defined as "Everything", and includes several billion galaxies.
