According to the [[materialism|materialist]] and [[uniformitarianism|uniformitarian]] view, what eventually became the solar system initially existed as a large, rotating [[cloud]] of [[dust]] and [[gas]], composed of hydrogen and helium produced in the [[Big Bang theory|Big Bang]] as well as small amounts of heavier [[element]]s. Around 4.57 billion years ago, the cloud began to contract, perhaps as a result of a [[shock wave]] from a nearby [[supernova]]. [[Inertia]] caused the rotating cloud to flatten into a disk. Most of the mass concentrated in the middle, and began to heat up. Eventually, the kinetic energy of the hydrogen was sufficient to overcome the [[electromagnetic]] repulsion between the protons, and fusion began. The resulting solar wind helped clear away much of the material which had not coalesced into planets or other orbiting bodies.<ref>"[http://www.tufts.edu/as/wright_center/cosmic_evolution/docs/text/text_plan_1.html Cosmic Evolution, Epoch 4: Planetary Evolution]."

Eventually, in a few billion years the sun will have expended most of it's Hydrogen, causing the outer shell to push outward and cool, turning into a Red giant, and Helium begins to be fused into Carbon. At this stage, Venus and Mercury will have been consumed by the now Red-Giant star, and possibly earth as well. Once the helium has been fused into carbon, there will not be enough heat to continue fusion to even heavier elements (as in larger stars), the core will collapse and the outer shell will be pushed off and form a Planetary Nebula, with a White Dwarf, and eventually a Black Dwarf at it's heart. <ref>http://imagine.gsfc.nasa.gov/docs/teachers/lessons/xray_spectra/background-lifecycles.html</ref>

The energy produced varies as the fourth power of the temperature--and at the temperatures thought to prevail in the sun's core, matter exists, not as ordinary matter with atomic nuclei and electrons, but as [[plasma]]--a form of super-hot matter in which atoms are totally denuded of their electrons.

The first equation above is assumed to be the rate-limiting step. The neutrinos produced should have an energy of 0.26 MeV--too little energy to be detectable by current technology. But processes occurring after this step ought to produce higher-energy neutrinos that ''would'' be detectable. Such neutrinos have been detected, but at a flux much smaller than predicted. This indicates that the presumed rates for these subsequent processes are higher than the true rates, or else the neutrinos produced somehow transform to a different type of neutrino that would be unobservable. That in turn would imply that neutrinos ''do'' have rest mass.<ref name=Britannica/>

According to current models, some of this energy is transferred to the surface by convection in the outer 20-30% of the body of the sun.<ref name=sunspot1/> [[Helium]] in this ''convective zone'' rises to or near the surface, releases its heat, and then sinks back to the center. Helium absorbs radiation more readily than does hydrogen, and for that reason the Sun is always getting marginally brighter with the passage of time.<ref name=Britannica/>

The magnetosphere oscillates in synchrony with the sunspots in a twenty-two-year cycle. The current amplitude of that cycle is 3.5 * 10²⁹ N-m-T. This amplitude has been decaying since creation, but relatively slowly, with a half-life of 13,170 Julian years. In fact, according to Humphreys<ref name=Humphreys/>, the sun's magnetic field has lost perhaps 25 percent of its strength since creation.

Measurements of the sun's magnetic dipole moment have not been exact enough to demonstrate whether the amplitude of the field's oscillations is constant or decaying. If those oscillations are in fact decaying, then the Sun cannot be a dynamo.<ref name=Humphreys/>

== Problems for uniformitarian theories posed by the sun ==

[[Uniformitarianism|Uniformitarians]] must admit that the sun continues to brighten as it continues to fuse hydrogen into helium. In fact, by uniformitarian estimates, the sun ought to be 40% brighter today than it was when the planets formed and 33% brighter than it was when life first formed (3.8 billion years ago by evolutionary assumptions). The Earth thus ought to be much hotter today than it once was--or rather, the Earth was much colder in the early days in which life has existed than it is today. The fossil record demonstrably does not bear this out.<ref name=Britannica/><ref name=Psarris>Psarris, Spike. ''Our Created Universe''. Seattle Creation Conference, 2007. Video presentation, 55 minutes.</ref> Uniformitarians answer that the Earth's atmosphere might be compensating for this increased brightness. (But these are often the same scientists who insist that industrial and transport-related introduction of [[carbon dioxide]] into Earth's atmosphere threatens to overheat the Earth, with potentially disastrous results.)

Uniformitarians have also had to admit that the sun rotates about 200 times more slowly than the [[nebula hypothesis]] would predict, simply on account of the contraction of the solar mass into its present volume. This violates of the Law of Conservation of Angular Momentum. This "angular momentum" problem has been apparent for hundreds of years and remains unresolved to this day.<ref name=Psarris/>

The sun's equatorial plane is inclined 7.25° to the ecliptic. (See [[Earth]].) By the nebula hypothesis, that inclination should be zero. The errant inclination poses an especially acute problem for the orbit of [[Neptune]]. Uniformitarians have speculated that a collision with an even larger object knocked the sun off a true perpendicular to its present inclination--but no scientist has offered a convincing speculation as to what that object might be.<ref name=Psarris/>

Conventional astronomers, [[Carl Sagan]] among them, insist that our star is mediocre and unremarkable. Yet the G-type of star is relatively rare, and furthermore its mass and position in the galaxy lie within very narrow tolerances for the support of life. The sun is also a singular star, not part of a binary--also a rare finding--and is remarkably stable in its energy output. These facts combine to make the sun an unusually hospitable star for a planet to have life on it.<ref name=Psarris/>

Finally, the only reason that uniformitarians can cite for a great age of the sun is the apparent great age of the Earth.<ref name=Britannica/>. Astronomer John Eddy has frankly admitted that the sun itself gives no clue to any such tremendous age, and that the acceptance of a very young age of the sun, like the six-thousand-plus years calculated by [[James Ussher]], might logically follow from a modicum of new evidence:<ref name=Psarris/><ref name=Ussher>Eddy, John.

Quoted in [[Larry Pierce|Pierce, Larry]], "The Forgotten Archbishop", in [[James Ussher]], ''[[The Annals of the World]]'', [[Larry Pierce]], ed., Green Forest, AR: Master Books, 2003 (ISBN 0890513600), pp. 891-2.</ref>{{cquote|There is no evidence based solely on solar observations, Eddy stated, that the Sun is 4.5-5 x 10⁹ years old. "I suspect," he said, "that the sun is 4.5-5 billion years old. However, given some new and unexpected results to the contrary, and some time for frantic recalculation and theoretical readjustment, I suspect that we could live with Bishop [[James Ussher|Ussher]]'s value for the age of the Earth and sun. I don't think we have much in the way of observational evidence in astronomy to conflict with that."}}
