The largest thing in the universe is a supervoid in deep space.
Geege Schuman stashed this in The Universe
In deep space lies a ‘supervoid’ that could be the biggest structure ever known
I bet he has a lot to say about this.
Well not much, except "The Cold Supervoid" could be a rock band name.
What's now emerging as the top hypothesis is a cosmic supervoid. All the stuff in the cosmos - galaxies and invisible dark matter - stretches across space in a vast web of sheets, tendrils, and filaments. In between are pockets of emptiness called voids, which come in many shapes and sizes. A really big one could act as a kind of distorting lens, making the CMB appear cooler than it really is.
It's difficult to imagine something as big as 1.3 billion light years across.
You're right, it's a great concept.
Seen anything else about the supervoid?
