What evidence can you give that we live in a galaxy?

Expert Solution & Answer
Check Mark
To determine

The evidence that life exists in a galaxy.

Answer to Problem 1RQ

The living organisms of the Milky Way galaxy are made up of the same constituents as the living organisms on earth are made up of. Hence, the life exists in a Milky Way galaxy.

Explanation of Solution

The galaxy in which life exists is the Milky Way Galaxy, the diameter of this galaxy is more than 80,000ly in diameter and the number of star are more than 100 billion.

The Milky Way Galaxy in which the life exists and which the living organisms live in has millions of stars, these stars are made up of the same basic constituents that the living organisms of the Earth and most of the atoms are made up of.

Therefore, the life exists in Milky Way galaxy.
