The Universe Is Mostly Empty Space

Vast stretches of the universe known as cosmic voids are not truly empty, yet they remain largely barren of stars. These massive, silent regions act as cosmic deserts that shape the structure of everything we see.

While these voids look like nothingness, they still contain a significant amount of matter that failed to clump together into galaxies. They act as distinct zones where the expansion of the universe behaves differently than in the dense clusters we inhabit. Most matter in the cosmos is actually concentrated into thin filaments, leaving these enormous gaps to make up the majority of space. It is a strange reminder that our home is just a small spark in a largely vacant cosmic web.
