Last July, I spent four days with my college literature professor and her husband at their 200-year-old stone cottage in County Clare, Ireland. The tiny house sat along a gravel road on a small (and very rural) peninsula between the Shannon River and the Atlantic Ocean.
Besides the peacefulness of the area, the main local attractions include the Cliffs of Moher and the Burren. I saw both, but it was the Burren that stuck out most in my mind. My professor told me that many people describe the unusual topography of the Burren as lunar. From far away the rocky terrain certainly looks like a copy of the moon’s surface, but an up close inspection reveals a place with a strong connection to life.
The Burren is a karst landscape, featuring limestone pavements broken up into clints and grikes. It looks as though a giant had raked the rocks in an attempt to farm. The grikes are a cornucopia of plant life. I was surprised to recognize flowers, like harebells, that I’ve seen in Montana.
In addition to the incredible variety of flora, the Burren also features an abundance of archaeological sites, including the Neolithic Poulnabrone Dolmen. Though much less impressive than Stonehenge, this particular portal tomb is older than both Stonehenge and the Pyramids of Egypt. The limestone, on which the dolmen stands, clocks in at around “340 million years” old. As I studied Poulnabrone, straddling a grike full of grass and ivy, I felt humbled by the age and history of the whole place. But how can we be so sure that the Burren really is millions of years old?
Recent research, dubbed the RATE project (Radioisotopes and the Age of The Earth), by the Institute of Creation Research (ICR) and the Creation Research Society, called into question the validity of radioisotopic dating results that show the earth to be anything older than about 6,000 years. The work was published in two volumes (2000 and 2005, respectively). RATE project researchers put forth four specific challenges to the currently accepted age of the earth, which were reviewed by Randy Isaac, executive director of the American Scientific Affiliation.
Isaac summarizes these scientists’ points in the June 2007 edition of Perspectives on Science and Christian Faith:
“The claim that the earth is approximately 6,000 years old is supported by biblical interpretation and from four areas of scientific study: helium diffusion in zircons, radiohalos in granites, isochron discordances, and the presence of trace amounts of carbon-14 (C-14) in pre-Cambrian material.”
The rest of Isaac’s article critiques the RATE project’s assertions. He notes numerous problems with the authors’ conclusions, among them the problems of intense heat and radiation that would have been produced by the proposed “accelerated decay rates during the Flood.” Heat of the magnitude required to fit the researchers’ criteria would have vaporized the earth without “an extraordinary mechanism of cooling.” Although the authors acknowledge this issue, they assert that such a miraculous mechanism must have existed and is yet to be discovered.
However, even if the heat could be cooled enough, the radiation produced by the heat would have caused considerable damage to Noah, his family, and all the animals on board the ark. (I can’t imagine any fish in the water would have been happy about it either.) Presently, no suggested solution to this problem exists, but as with the heat issue, the RATE group maintains that it will be solved through further research. Additionally, the group’s stance would need to be validated by evidence for periodic changes in the otherwise steady radioactive decay rates.
Isaac’s concern is that the RATE team’s conclusions violate integrity in science. They acknowledge that 1) their results present huge difficulties; 2) therefore, their results are not compatible with currently accepted scientific processes; and 3) they agree that there are mountains of evidence for billions-years-old earth. Yet they still draw the conclusion that their own studies support a young-earth interpretation of both nature and Scripture and enthusiastically promote it as such.
This month Perspectives on Science and Christian Faith published the RATE group’s response to Isaac’s criticisms and his reply to them. They insist that, “To weakly assert the significance of this evidence would not only do a great disservice to Christians but also to the advancement of science.”
Yet Isaac again points out that in the face of the evidence in favor of steady decay rates and the proven accuracy of current radioisotope dating methods, the RATE team continues to “postulate accelerated decay rates to accommodate the idea of a young earth.” It seems to me that this is just as irresponsible as reworking naturalistic interpretations to discount the growing evidence for design.
Though scientific hypotheses may waver or evolve, it is a comfort to know that the God who orchestrated the carving of the beautiful patterns in the Burren’s ancient limestone “is the same today and yesterday and forever.”
