So, it is not surprising that Brennecka’s team has now found a need to tweak the age formulas used for dating meteoritic material.Although it is apparent that millions of years worth of decay—at today’s slow rates—has occurred in isotope decay systems, it is clear that the decay occurred rapidly, during a period of extreme acceleration.These discordant dates should not be evident if the assumption of rate constancy—which underlies radioisotope dating of igneous materials and is used to support the “billions of years” age for the solar system—is accurate.
Even the solar system has been dated using one of these systems, by measuring the amount of a decaying element and comparing it to the amount of its stable (decayed) daughter material in meteorites.
However, a recent analysis using state-of-the-art equipment found that a basic assumption underlying one of these clock systems needs to be re-evaluated.
Only in this way could Helium have become trapped in granites, Although Brennecka and his colleagues detected only a small difference in the Uranium isotopes within the same rock, this was enough to cast a measure of doubt on a procedure that has been deemed nearly infallible for many decades.
And this dovetails with other valid research which has unearthed enough other data to call into question the assumed reliability of isotope clock dating systems.
To understand this process we must first understand a little bit about the atoms themselves and how they get their names.
