The Hercules-Corona Borealis Great Wall is the largest known structure in the universe. It is an enormous cluster of galaxies forming a giant structure which is about 10 billion light years in length, 7.2 billion light years wide, and almost 1billion light years thick. It is 10 billion light years away in the constellation of Hercules and Corona Borealis. It was discovered in November 2013 by mapping gamma ray bursts; these are very luminous explosions of distant and massive stars which are the most powerful explosions in the universe. A typical burst releases more energy in less than a tenth of a second than the Sun will release in its entire life of 10 billion years. Buy measuring these bursts, astronomers are able to determine this structure's length at 10 billion light years. The Great Wall appears to exceed the maximum structural size predicted by universal inflationary models. This structure, if it is that large, would put in dispute the many theories about the evolution of the universe. The Great Wall is eight times larger than the allowed limit, contradicting Einstein's theory called the cosmological principle. It's a puzzle as to how the Great Wall came to be at all. It actually inflated to 10 billion light years in 3.8 billion years. For now, the existence of the Great Wall is still a mystery for cosmologists.
