Nucleosynthesis in the universe

The exact temperature depends sensitively on the density of the protons and neutrons at that time. The synthesized elements are dispersed into the interstellar medium during the planetary nebula or supernova stage with supernova being the best way to distribute the heavy elements far and wide.

Relative abundance of various elements following the Big Bang. This stellar debris formed the seeds of comets, planets, and even you! The Nucleosynthesis in the universe is from the Greek word galaxias, literally meaning "milky", a reference to the Milky Way galaxy.

Where did it all come from? Like to learn more? Since the universe is presumed to be homogeneousit has one unique value of the baryon-to-photon ratio. Nucleosynthesisfrom 3 minutes to 20 minutes: You will find out where the hydrogen and most of the helium atoms came from in the cosmology chapter.

Since the Big Bang, the universe has gone through several eras distinguished by the behavior of the universe's fundamental forces and particles. Notice that at higher temperatures, only free protons and neutrons existed. The total mass of a star is the principal determinant in its evolution and eventual fate.

All of the rest of the elements of the universe were produced by the stars in nuclear fusion reactions. The term universe may be used in slightly different contextual senses, denoting such concepts as the cosmosthe world, or nature.

The star's internal pressure prevents it from collapsing further under its own gravity. The discrepancy is a factor of 2. The dark matter must be made of particles that are not the usual protons, neutrons, electrons, etc.

Astronomers can determine the massage, chemical composition and many other properties of a star by observing its spectrum, luminosity and motion through space. This is the closest that current physics can get to the absolute beginning of time, and very little can be known about this period.

The process can be reversed if the photons have enough energy i.

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. Massive red giants are also able Nucleosynthesis in the universe make small amounts of elements heavier than iron up to mercury and lead through a slower combination of neutrons with heavy nuclei, but supernova probably generate the majority of elements heavier than iron and nickel and certainly those heavier than lead up to uranium.

If one assumes that all of the universe consists of protons and neutrons, the density of the universe is such that much of the currently observed deuterium would have been burned into helium Each atom is rearranged or re-used.

As the strong nuclear force separates from the other two, particle interactions create large numbers of exotic particlesincluding W and Z bosons and Higgs bosons the Higgs field slows particles down and confers mass on them, allowing a universe made entirely out of radiation to support things that have mass.

How did it all begin? Stars around the mass of our Sun can synthesize helium, carbon, and oxygen. It can be perceived with this UVS atomic model that those features and characteristics of local symmetry formed in an atom, had occurred as a result of the manifold manifestation of Lagrangian points with its chirality pairs, and are resonated to form within each of the three spheroidal structures with intrinsic angular momentum.

From the moment of initial expansion to seconds afterwards, cosmologists suspect that the four fundamental forces at work in the universe today strong, weak, electromagnetism, and gravity were combined into a single unified force.

The outer major planets Saturn, Uranus, and Neptune, can be perceived as the nested positrons coalesced spheroidal bodies of stellar materials formed with the cyclonic spinor field of the L1 Lagrangian points within the outer shell walls of the L, M, and N shells respectively.

Stars are massive, luminous balls of plasma held together by gravity. To reflect this, universe, galaxies and stars might under go a name change soon.

Nucleosynthesis

Click "Play" to see how heavier elements are synthesized. The gravitational constant G appears to truly be constant.

As noted above, in the standard picture of BBN, all of the light element abundances depend on the amount of ordinary matter baryons relative to radiation photons. See my copyright notice for fair use practices. Big Bang nucleosynthesis produced no elements heavier than lithium.

In the UVS worldviewthe entire Solar System in its nested encapsulation, can be coherently perceived as a macroscopic scale electron of its galactic scale atom.

R diagramallows the age and evolutionary state of a star to be determined. Quarks and anti quarks annihilate each other upon contact, but, in a process known as baryogenesis, a surplus of quarks about one for every billion pairs survives, which will ultimately combine to form matter.Discussion big bang nucleosynthesis.

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). Matter to Energy to Matter Conversion Chapter index in this window — — Chapter index in separate window This material (including images) is copyrighted!.See my copyright notice for fair use practices.

Einstein's equation E = mc 2 says that mass can be converted to energy and vice versa. If you extrapolate the expansion rate and temperature of the universe.

The Era of Atoms (, years – 1 billion years or so) began as the universe finally cooled and expanded enough for the nuclei to capture free electrons, forming fully-fledged, neutral atoms.

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) and formed in much smaller numbers.

The Era of Atoms (, years – 1 billion years or so) began as the universe finally cooled and expanded enough for the nuclei to capture free electrons, forming fully-fledged, neutral atoms. See the UVS topic on "The spheroidal pushed-in gravity" that elaborates on the causality for the mass effect of wsimarketing4theweb.com cognitive paradox that renders the obscured observation for the structure of atom, could thus be meticulously resolved with its underlying structure and mechanism illustrated.
