Dark Matter and the Cosmic Web
Quick fact
Although we cannot see dark matter directly, its gravitational pull has steered ordinary matter into the vast network of filaments and clusters that we call the cosmic web. Without dark matter, galaxies would be spread far more evenly, and the web-like structure would not exist.
Why this is interesting
If you could see the entire universe in a single snapshot, you'd notice galaxies are not scattered randomly—they form a giant web of filaments and empty voids. What invisible hand weaves this cosmic pattern?
