An Introduction to Dr. Mario Livio:

The Universe is big. Sometimes, it can feel a little too big. The sun, which is not a particularly large star, 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.***

Humanity once assumed that we were the center of the cosmos, but as we come to the realization that our universe is more spectacular than we ever imagined, it becomes more difficult to define our place in it. 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.
