The Fractal Structure of Large-Scale Cosmic Filaments

Quick fact

Simulations show that the cosmic web's filamentary network is remarkably self-similar over a range of scales, from a few million to hundreds of millions of light-years, much like the branching of a fractal tree.

Why this is interesting

If you zoom out from Earth, the galaxies aren't scattered randomly—they form a gigantic web of filaments and voids. What if the entire universe is just one structure repeating itself at ever larger scales?
