There’s Growing Evidence That the Universe Is Connected by Giant Structures

Becky Ferreira


Quote:Scientists are finding that galaxies can move with each other across huge distances, and against the predictions of basic cosmological models. The reason why could change everything we think we know about the universe.



Quote:Galaxies within a few million light years of each other can gravitationally affect each other in predictable ways, but scientists have observed mysterious patterns between distant galaxies that transcend those local interactions.

These discoveries hint at the enigmatic influence of so-called “large-scale structures” which, as the name suggests, are the biggest known objects in the universe. These dim structures are made of hydrogen gas and dark matter and take the form of filaments, sheets, and knots that link galaxies in a vast network called the cosmic web. We know these structures have major implications for the evolution and movements of galaxies, but we’ve barely scratched the surface of the root dynamics driving them.

Scientists are eager to acquire these new details because some of these phenomena challenge the most fundamental ideas about the universe.
