The sun is roughly a million times the size of the Earth. If the universe were scaled down so that the Sun were only 5 feet in diameter, the nearest star to us would still be 25,000 miles away. There is so much ‘empty’ space in the universe that when the Milky Way and Andromeda galaxies collide four billion years into the future, chances are that not a single star, of the more than a trillion involved, will collide with any other star.

In this film, astrophysicist Dr. Mario Livio reveals that in order to understand something unimaginably huge, it is important to remember the significance of the small.
