From the eyewitness testimony of God’s Word, the billions of years that such vast amounts of radioactive processes would normally suggest had not taken place.
So it was clear that the assumption of a constant, slow decay process was wrong.
The rules are the same in all cases; the assumptions are different for each method.
To explain those rules, I'll need to talk about some basic atomic physics. Hydrogen-1's nucleus consists of only a single proton.
In another very important paper, scientists from the RATE group summarized the pertinent facts and presented further experimental data. This effectively limits the age of all buried biota to less than (at most) 250,000 years.
(When one takes into account the probability that before the Flood the ratio of radioactive to ‘normal’ carbon was much lower, C was primordial (existing from the very beginning), and not produced by cosmic rays—thus limiting the age of the entire earth to only a few thousand years.
Radiometric dating methods are the strongest direct evidence that geologists have for the age of the Earth.
All these methods point to Earth being very, very old -- several billions of years old.Nevertheless they contained radioactive carbon, even though, if the billion-year age were correct, they ‘shouldn’t have’.This is exceptionally striking evidence, because a diamond has remarkably strong lattice bonds (that’s why it’s the hardest substance known), so subsequent atmospheric or biological contamination should not find its way into the interior.With the release of key peer-reviewed papers at the 2003 ICC (International Conference on Creationism), it is clear that RATE has made some fantastic progress, with real breakthroughs in this area.When physicist Dr Russell Humphreys was still at Sandia National Laboratories (he now works full-time for ICR), he and Dr John Baumgardner (still with Los Alamos National Laboratory) were both convinced that they knew the direction in which to look for a definitive answer to the puzzle of why radiometric dating consistently gives ages of millions and billions of years.(These include the variety of elements used in ‘standard’ radioisotope dating, mature uranium radiohalos and fission track dating.) It would be hard to imagine that geologic processes alone could explain all these.
