Dense areas pulled in An increasing number of issue through gravity, and the greater enormous they turned, the more make any difference they could pull in by gravity, forming stars, galaxies and bigger structures generally known as clusters, superclusters, filaments and partitions, with "fantastic walls" of thousands of galaxies reaching in excess of a billion light-weight several years in duration. Much less dense areas didn't increase, evolving into area of seemingly empty space identified as voids.

From studying the consequences of gravity on both equally issue and light, it's been uncovered which the universe has a great deal more issue than is accounted for by visible objects; stars, galaxies, nebulas and interstellar gasoline. This unseen make a difference is named darkish matter,[16] (dim signifies that there's a wide range of robust oblique proof that it exists, but we haven't nonetheless detected it straight) having come into existence alongside the rest of the physical universe ahead of steadily accumulating right into a foam-like structure of filaments and voids and allowing for other forms of issue to type jointly into seen structures.
