Hace 2 días · Long before the formation of stars and planets, the early universe was smaller, much hotter and, starting 10 −6 seconds after the Big Bang, filled with a uniform glow from its white-hot fog of interacting plasma of photons, electrons, and baryons.
Hace 1 día · Overview Chronology in five stages Diagram of evolution of the (observable part) of the universe from the Big Bang (left), the CMB-reference afterglow, to the present. For the purposes of this summary, it is convenient to divide the chronology of the universe since it originated, into five parts.It is generally considered meaningless or unclear whether time existed before this chronology:
Hace 4 días · The Cosmic Microwave Background is the remnant heat left over from the initial years immediately following the Big Bang. It is a crucial piece of evidence that supports the Big Bang Theory.

Hace 1 día · A supernova ( pl.: supernovae or supernovas) is a powerful and luminous explosion of a star. A supernova occurs during the last evolutionary stages of a massive star, or when a white dwarf is triggered into runaway nuclear fusion.
Hace 1 día · Today the universe has expanded into an age and size that is physically only in parts observable as the observable universe, which is approximately 93 billion light-years in diameter at the present day, while the spatial size, if any, of the entire universe is unknown.
Hace 3 días · A supernova of a star more than about 10 times the size of our sun may leave behind the densest objects in the universe—black holes. The Crab Nebula is the leftover, or remnant, of a massive star in our Milky Way that died 6,500 light-years away.
Hace 6 días · Wave-particle duality is the term for the fact that fundamental objects in the universe such as photons or electrons appear to exhibit aspects of either waves or particles depending on the experiment.
