They called the study the RATE (Radioisotopes and the Age of the Earth) project.Upon completion of the eight-year investigation, the team announced the results at a conference in 2005.
C-12 is stable, meaning it does not decay into other elements over time. It is formed when cosmic radiation strikes N-14 (Nitrogen), converting it into C-14, and it decays back into N-14, with a half-life of 5730 years, meaning that for any sample of C-14, half of it will decay back into N-14 every 5730 years.
Carbon-14 is used to date dead plants and animals, because plants and animals incorporate C-14 into their bodies by eating, drinking, and breathing in an environment containing C-14.
The RATE team, however, because of their unshakable Biblical faith in a 6,000 year old Earth, rejects uniformitarianism (Humphreys 20) and argues that the rate of decay was greatly accelerated during the first two days of Creation Week and during the year-long Flood of Noah (De Young 200-151).
This paper examines the evidence RATE cites for believing that decay has been accelerated, the proposed mechanisms for that acceleration, and several difficulties with the theory.
Consequently they reasoned that decay rates must have changed and presented evidence for such a change.
In this article, I summarize the evidence the group presented and provide a response.These studies provide strong evidence that Earth formed over 4.5 billion years ago.Because a 4.5-billion-year-old Earth conflicts with a popular interpretation of Genesis (called the “calendar day” or “24-hour day”), a group of scientists adhering to this interpretation decided to study the validity of radioisotope dating in order to assess how it might comport with a 6,000- to 10,000-year-old Earth.Over 100 years ago, scientists discovered radioactivity and began realizing the potential of dating different objects using radioactive materials contained within them.They have since developed numerous techniques that utilize a suite of radioisotopes to date and crosscheck those dates. It would be hard to imagine that geologic processes could explain all these.
