Nucleosynthesis theory

Big Bang nucleosynthesis

Or more precisely, allowing for the finite precision of both the predictions and the observations, one asks: The UVS atomic model In a similar recursive manner, the 32 Lagrangian points in the N shell are harmonically manifested on the 4s, 4p, 4d, and 4f subshells.

Synthesis of these elements occurred either by nuclear fusion including both rapid and slow multiple neutron capture or to a lesser degree by nuclear fission followed by beta decay. The nuclei of these elements, along with some 7Li and 7Be are considered to have been formed between and seconds after the Big Bang when the primordial quark—gluon plasma froze out to form protons and neutrons.

Those atoms are rearranged to produce the vast variety of things around and in you. From the UVS perspective, the motions of Jupiter and all other major planets, are governed by the nested dual-core orbitals of the nested Solar System electron shell in its nested L1 and L2 Lagrangian points, which spin around the BOTSS to render the effect of elliptic orbits in two-axis spin with their apsidal precessions to apparently rotate and revolve around the Sun.

In the years immediately before World War II, Hans Bethe first elucidated those nuclear mechanisms by which hydrogen is fused into helium. After about 15 minutes from the Big Bang, the universe had expanded and cooled so much that fusion was no longer possible.

All of the protons, neutrons, and electrons in matter today were created in the first few seconds after the Big Bang.

Big Bang Nucleosynthesis

Extremely small amounts of Lithium-7 were also produced during the early universe nucleosynthesis process. It shows that there cannot be more than the three types of neutrinos already given by the Standard Model of Particle Physics. Such a process would require that the temperature be hot enough to produce deuterium, but not hot enough to produce helium-4, and that this process should immediately cool to non-nuclear temperatures after no more than a few minutes.

If you extrapolate the expansion rate and temperature of the universe back to much closer to the Big Bang than when the cosmic microwave background was produced, you find that within the first few seconds, the energy of the photons was great enough to create particles like electrons and protons.

The antimatter counterpart of an ordinary particle has the same mass and opposite charge of the ordinary particle if it is not neutral. The BBFH theory, as it came to be known, postulated that all the elements were produced either in stellar interiors or during supernova explosions.

That paper defined new processes for the transformation of one heavy nucleus into others within stars, processes that could be documented by astronomers. Each atom is rearranged or re-used. Since the universe is presumed to be homogeneousit has one unique value of the baryon-to-photon ratio.

The primary L1 and L2 Lagrangian points from the 1s subshell, are also harmonically manifested on the 2s subshell, which are labeled as Ls and Ls in the illustrated UVS atomic model on right.

That fusion process essentially shut down at about 20 minutes, due to drops in temperature and density as the universe continued to expand.

This is why there was still some ordinary matter left over when all the antimatter had been annihilated. Nucleosynthesis is the process that creates new atomic nuclei from pre-existing nucleons, primarily protons and neutrons. The first nuclei were formed about three minutes after the Big Bang, through the process called Big Bang nucleosynthesis.

Problems practice. Hydrogen fusion in the sun is a multistep reaction, but the net result is that four hydrogen atoms fuse into one helium atom (plus a bunch of junk). Nucleosynthesis is the process that creates new atomic nuclei from pre-existing nucleons, primarily protons and first nuclei were formed about three minutes after the Big Bang, through the process called Big Bang elleandrblog.comeen minutes later the universe had cooled to a point these processes ended, so only the fastest and simplest reactions occurred, leaving our.

Discussion 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 ( s).

Hydrogen and helium and some lithium, boron, and beryllium were created when the universe was created.


Stellar nucleosynthesis is the theory explaining the creation (nucleosynthesis) of chemical elements by nuclear fusion reactions between atoms within the stars. Stellar nucleosynthesis has occurred continuously since the original creation of hydrogen, helium and lithium during the Big is a highly predictive theory that today yields excellent agreement between calculations based upon it.
