Of course, the question has crossed your mind, at least once: What would it be like to fly through the universe? Now you can find out.
According to NASA's Astronomy Picture of the Day website, the clip above offers perhaps the best simulation yet. The animated flight takes you through 400,000 galaxies (each spot represents one galaxy) and brings you to a point 1.3 billion light years from Earth. And that's just a small slice of the larger universe. Miguel Aragon-Calvo and Alex Szalay (both of Johns Hopkins) produced the video along with Mark Subbarao of the Adler Planetarium using images from the Sloan Digital Sky Survey.
