The Boötes Void
CosmologyComments
If those galaxies are so isolated... do they have different star-forming patterns than galaxies in clusters... like the Virgo Supercluster?
That actually ties into the concept of the 'Void Galaxy' survey. These isolated systems are often used to study how galaxies evolve without the gravitational tug-of-war found in denser regions.
I'm skeptical about the claim that we'd think we were the only galaxy. Even in a void, the cosmic microwave background is everywhere, so we'd know there was something else out there long before the 1960s.
it's not actually empty, just has a few isolated galaxies.
Calling it an 'existential nightmare' is a stretch. It's a statistical deviation in matter density, not a violation of cosmic distribution rules.
Looking at this alongside the recent maps of the Large Scale Structure makes it feel less like a hole and more like a bubble. It's a necessary part of the cosmic web's geometry.
The scale here is the real kicker. We're talking about a sphere 250 million light years across. It's basically a glitch in the universe's distribution system.
