The older a sample is, the less (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to around 50,000 years ago, although special preparation methods occasionally permit accurate analysis of older samples.The idea behind radiocarbon dating is straightforward, but years of work were required to develop the technique to the point where accurate dates could be obtained. The method was developed by Willard Libby in the late 1940s and soon became a standard tool for archaeologists.
They point to a catastrophic origin for granites, consistent with the biblical timeframe for earth history and God’s judgment during the Flood.
Radioactive dating is very interesting because often this is where history and science mingle.
Radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements--has been in widespread use for over half a century.
There are over forty such techniques, each using a different radioactive element or a different way of measuring them.
One example of radioactive dating is carbon-14 dating.
Carbon-14 dating can be used on anything that was once alive, be it plant or animal.Yet few people know how radiometric dating works or bother to ask what assumptions drive the conclusions. This figure wasn’t established by radiometric dating of the earth itself. Radiohalos shouldn’t exist, according to conventional wisdom!Though they are very tiny, polonium radiohalos have a huge message that cannot be ignored.Proponents of evolution publicize radioisotope dating as a reliable and consistent method for obtaining absolute ages of rocks and the age of the earth.This apparent consistency in textbooks and the media has convinced many Christians to accept an old earth (4.6 billion years old).Many accept radiometric dating methods as proof that the earth is millions of years old, in contrast to the biblical timeline.
