Astronomy. Universe's Largest Structure is a Cosmic Conundrum. Astronomers have found a mind-bogglingly large structure -- so big it takes light 10 billion years to traverse -- in a distant part of the universe.
The discovery poses a conundrum to a fundamental tenet of modern cosmology, which posits that matter should appear to be distributed uniformly if viewed at a large enough scale. NEWS: Scientists Discover Universe's Largest Structure The newly found structure is more than double the size of the previous record-holder, a cluster of 73 quasars referred to as the Huge-LQG, or Large Quasar Group, which spans 4 billion light-years. It is six times larger than the 1.4-billion-light year diameter Sloan Great Wall.
Light travels at about 671 million miles per hour, or about 6 trillion miles per year. The Scale of the Universe 2. Ten of the Most Interesting Structures of the Universe. To quote the late Douglas Adams (the beloved author of “The Hitckhikers Guide to the Galaxy” books): “Space is big.
You just won’t believe how vastly, hugely, mind- bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space.” Sci-Tech.
