The Cosmic Web: Voids, Filaments, and Walls
Quick fact
The universe's galaxies are distributed on enormous sheets and filaments, forming a vast network called the 'cosmic web', with voids that can span hundreds of millions of light-years—the biggest structures in the universe.
Why this is interesting
If you could zoom way out from Earth and see the entire universe at once, you'd find that galaxies aren't scattered randomly. Instead, they're arranged into a giant, foamy web of filaments and walls surrounding enormous empty voids. What created this pattern?
