Cosmic superclusters, the Universe’s largest structures, don’t actually exist (Synopsis)

“It’s the gravity that shapes the large scale structure of the universe, even though it is the weakest of four categories of forces.” -Stephen Hawking Galaxies don’t just exist in isolation in our Universe, but are often found bound together as a part of even grander structures. Our own Milky Way is bound in a … Read moreCosmic superclusters, the Universe’s largest structures, don’t actually exist (Synopsis)
