OR

0.000000000000000000000000000000000000000000000000000000000003016 %

#### Explanation:

The Earth has a radius of 3959 miles, which gives us a volume of approximately 259,923,241,563 cubed miles.

Now the observable Universe has a radius of 46.6 Billion light years. 1 light year is 5,879,882,207,943 miles, so it has an approximate volume of $8.617 \text{ x } {10}^{70}$ cubic miles or 8617 followed by 67 zeroes.

Dividing the volume of the Earth by that of the Universe, we get that the earth compromises $3.016 \text{ x } {10}^{-} 60$ % of the Universe, or if you prefer it written without the exponent:

0.000000000000000000000000000000000000000000000000000000000003016 %
