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

[[Uniformitarianism|Uniformitarians]] commonly estimate that the Sun is about 4.5 billion years old, has consumed about half its nuclear fuel ([[hydrogen]]), and will begin to die within about 5 billion years.<ref name=thinkquest>"[http://library.thinkquest.org/29394/sun.htm Entry for 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/>
