Importance of nucleosynthesis in big bang
WitrynaOver the last two decades big-bang nucleosynthesis (BBN) has emerged as one of the cornerstones of the big bang, joining the Hubble expansion and the cosmic microwave background radiation (CBR) in this role. Of the three, big-bang nucleosynthesis probes the Universe to the earliest times, from a fraction of a second to hun-dreds of seconds. Witryna1 gru 2024 · 2 24.

WitrynaThere also four types of Nucleosynthesis namely the Big Bang, Stellar, Explosive Nucleosynthesis, and Cosmic ay Spallation. Big Bang Nucleosynthesis is the reaction that came within three minutes from the formation of the Universe. It is also responsible for the high levels of different elements, especially Helium in outer space.
