The explosion had the energy of approximately 9000 type Ia supernovae if the emission was isotropically emitted, and the gas jets emitting the initial gamma rays moved at a minimum velocity of approximately 299,792,158 m/s (99.9999% the speed of light), making this blast one of the most extreme recorded.

Universe Sandbox is a series of simulation video games.In Universe Sandbox, users can see the effects of gravity on objects in the universe and run scale simulations of the Solar System, various galaxies or other simulations, while at the same time interacting and maintaining control over gravity, time, and other objects in the universe, such as moons, planets, asteroids, comets, and black holes.
A universe in which most of the comics published by Dynamite Entertainment are set in, including Army of Darkness, Red Sonja, Vampirella, Project Superpowers, Green Hornet, Xena: Warrior Princess, and more. This shared universe is also known as Earth-818793 as part of the Marvel multiverse. E-Man's Universe E-Man No. 1 1973
The timeline of the Universe lists events from its creation to its ultimate final state. For a timeline of the universe from the present to its presumed conclusion, see: Timeline of the far future; Chronology of the universe; Timeline of the universe
[94] [95] The jets of gamma-ray bursts are ultrarelativistic, and are the most relativistic jets in the universe. [ 96 ] [ 97 ] The matter in gamma-ray burst jets may also become superluminal , or faster than the speed of light in the jet medium, with there also being effects of time reversibility .
The chronology of the universe describes the history and future of the universe according to Big Bang cosmology.. Research published in 2015 estimates the earliest stages of the universe's existence as taking place 13.8 billion years ago, with an uncertainty of around 21 million years at the 68% confidence level.
The most recent naked-eye supernova was SN 1987A, which was the explosion of a blue supergiant star in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. Theoretical studies indicate that most supernovae are triggered by one of two basic mechanisms: the sudden re-ignition of nuclear fusion in a white dwarf , or the sudden ...
SN 1054 remnant (Crab Nebula)A supernova is an event in which a star destroys itself in an explosion which can briefly become as luminous as an entire galaxy.This list of supernovae of historical significance includes events that were observed prior to the development of photography, and individual events that have been the subject of a scientific paper that contributed to supernova theory.
