There's a Hole in the Universe 330 Million Light-Years Wide | Science Documentary for Sleep

There are 60 galaxies inside the Boötes Void. There should be 10,000. If our galaxy were at its center, we wouldn't have known other galaxies existed until the 1960s. This is the story of the largest void in the observable universe — how it was found by accident, why it shouldn't be this empty, and what it tells us about a cosmos that is mostly nothing. A deep space sleep documentary exploring the Boötes Void, cosmic voids, the large-scale structure of the universe, dark energy, and the unsettling possibility that we may be living inside a void of our own. Researched from peer-reviewed astrophysics. Designed for deep sleep.
