How much space in the universe does Earth take up? How would you describe this as an analogy, like a grain of sand in comparison to our entire Earth?

Earth is, to the Universe, smaller than 1 atom of 1 grain of sand is to the Earth.


The Earth is
#3.016" x "10^-60# % of the Universe
0.000000000000000000000000000000000000000000000000000000000003016 %

That is an insurmountable number to imagine, and even analogies fail here. To compare, a grain of sand is #5.726" x "10^-32# % of the size of the Earth, so we would need to break the grain of sand into each of it's approximate 50,000,000,000,000,000,000 individual atoms, and STILL only one of those atoms would be about 200,000,000 times bigger in comparison to the size of the Earth than Earth is to the size of the Universe.
