How does nucleosynthesis support the big bang

WebDiscussion big bang nucleosynthesis. By the first millisecond, the universe had cooled to a few trillion kelvins (10 12 K) and quarks finally had the opportunity to bind together into free protons and neutrons. Free neutrons are unstable with a half-life of about ten minutes (614.8 s) and formed in much smaller numbers. WebThe Big Bang model is supported by three important observations: The expansion of the Universe as deduced from the distance - redshift relationship for galaxies and described by the Hubble law.

In physical cosmology, Big Bang nucleosynthesis (abbreviated BBN, also known as primordial nucleosynthesis) is the production of nuclei other than those of the lightest isotope of hydrogen (hydrogen-1, H, having a single proton as a nucleus) during the early phases of the Universe. Primordial nucleosynthesis is believed by most cosmologists to have taken place in the interval from roughly 10 seconds to 20 minutes after the Big Bang, and is calculated to be responsible fo… WebTheories without a "hot big bang" need to propose alternative mechanisms for the CMB. None are able to reproduce the spectrum. Nucleosynthesis. The universe is mostly hydrogen and helium (about 24% of the mass is helium).
