The scale of the solar system is even more mind-blowing. Using a grain of sand to represent the sun, the closest star is another grain of sand 5 miles away.
The distance between galaxies is unimaginably immense.
The average density of the universe is estimated a 1 to 3 hydrogen atoms per square meter.
