60 Galaxies Where 2,000 Should Be - The Boötes Void

The Boötes Void spans 330 million light-years — with only 60 galaxies where 2,000 should be. How does this much nothing exist?

The Boötes Void is not a black hole. It is not a dark cloud. It is a transparent volume of near-absence, where the few surviving galaxies are running experiments in isolation that cannot be replicated anywhere else in the observable universe. This video traces how the void formed, names the three galaxies still inside it, and ends with a question that reframes everything: what if Earth sits inside a void too?
