This timeline of the big bang describes the events according to the widely accepted scientific theory of the big bang, using the cosmological time parameter of comoving coordinates best available measurements as of 2009 suggest.
Overview according to the big bang theory, the following sequence of events is believed to have occurred the starting point for this timeline, 1373 ± 012 billion years ago 1, is the time at which in general relativity there exists a.

We present an overview of the standard model of big bang nucleosynthesis (bbn), which describes the production of the light elements in the early universe the theoretical prediction for the abundances of d, 3 he, 4 he, and 7 li is. [/thrive_custom_box] suddenly, reviewing mission data, you see all nucleosynthesis stops abruptly at three minutes after the big bang now, the universe transforms into a large, dark and still place you wonder, if nucleosynthesis.

Timeline of the big bang - early universe - photon epoch - nucleosynthesis nucleosynthesis only lasts for about seventeen minutes, since the temperature and density of the universe has fallen to the point where nuclear fusion.
2013/06/06 big bang events event evidence big bang nucleosynthesis occurred between 3 and 20 minutes after the big bang happened this period of time is responsible for the elemental production of hydrogen, deuterium, helium. Big bang nucleosynthesis began a few seconds after the big bang, when the universe had cooled sufficiently to allow deuterium nuclei to survive disruption by high-energy photons this time is essentially independent of dark matter. Despite the self-consistency and remarkable success of the big bang model in describing the evolution of the universe back to only a fraction of a second, a number of unanswered questions remain regarding the initial state of the. 2014/01/07 so, let us take a moment to delve into the big bang–into the timeline of everything that has ever existed before the big bang: cosmologists have come up with several possible speculations as to what existed before.
