The slight flaw in Old Earth arguments is their reliance on the assumption that the [[Radiometric dating|rate of radioactive decay]] remains constant over billions of years. In fact, a large number of physical processes, such as neutron capture and fluctuations in solar radiation, can affect the rate of radioactive decay of elements in the Earth's crust and render radioactive dating measurements unreliable with errors up to 5%, depending upon the specific methods used. However, this 5% difference is mediocre when compared to billions of years.<ref>http://www.sciencedirect.com/science/article/pii/S0899536205000138#bib6</ref> | The slight flaw in Old Earth arguments is their reliance on the assumption that the [[Radiometric dating|rate of radioactive decay]] remains constant over billions of years.
