I’ve been thinking about this excerpt of “Why We Need to Study Nothing,” by Paul M. Sutter since I read it earlier this month (emphasis my own): Because voids don’t change much through their lives, they retain a memory of the young universe. If you want to know what our universe was like billions of years ago, you can’t look into a galaxy or cluster—too much has changed. But a void? A void today is pretty much the same as a void billions of years ago.
