In 1976, two astronomers on an Arizona mountain drew a wedge of galaxies and found a region where the dots simply stopped. The gaps have only grown since: emptier than any vacuum we can make, hundreds of millions of light years wide, and one of them is pushing our galaxy right now. So how big is the biggest thing in the universe, and what does that make us?
Tonight's path runs from an old globe marked with dragons to a cold patch on the oldest light in the sky.
Settle in and let this slow walk through the emptiest places in the universe keep you company tonight. Subscribe to Sundown Science if you enjoy the long way around the universe.
