The universe also has vast regions of relative emptiness; the largest known void measures 1.8 billion ly (550 Mpc) across. [114] Comparison of the contents of the universe today to 380,000 years after the Big Bang, as measured with 5 year WMAP data (from 2008). [115] Due to rounding, the sum of these numbers is not 100%.
Discovered through gamma-ray burst mapping. Largest-known regular formation in the observable universe. [8] Huge-LQG (2012–2013) 4,000,000,000 [9] [10] [11] Decoupling of 73 quasars. Largest-known large quasar group and the first structure found to exceed 3 billion light-years. "The Giant Arc" (2021) 3,300,000,000 [12] Located 9.2 billion ...
The Huge-LQG was estimated to be about 1.24 Gpc in length, by 640 Mpc and 370 Mpc on the other dimensions, and contains 73 quasars, respectively. [5] Quasars are very luminous active galactic nuclei, thought to be supermassive black holes feeding on matter.
The universe's size is unknown, and it may be infinite in extent. [14] Some parts of the universe are too far away for the light emitted since the Big Bang to have had enough time to reach Earth or space-based instruments, and therefore lie outside the observable universe. In the future, light from distant galaxies will have had more time to ...
The Cosmic Calendar is a method to visualize the chronology of the universe, scaling its currently understood age of 13.8 billion years to a single year in order to help intuit it for pedagogical purposes in science education or popular science.
The Giant Arc is a large-scale structure discovered in June 2021 that spans 3.3 billion light years. [1] The structure of galaxies exceeds the 1.2 billion light year threshold, challenging the cosmological principle that at large enough scales the universe is considered to be the same in every place (homogeneous) and in every direction ().
I remember watching a video on how the universe might end. It was a 30-minute time lapse of what occurs from the Big Bang to the "end." EARTH'S entire existence from beginning to end wasn't even a ...
[6] [7] [8] The current version of The Scale of the Universe 2 uses Pixi.js instead of Flash, ported by Matthew Martori. [6] The Scale of the Universe was featured on NASA's Astronomy Picture of the Day on October 7, 2018. [9] In 2020, animation studio Kurzgesagt released the app Universe in a Nutshell, which took inspiration from The Scale of ...
