Today, though, a friend of mine shared this youtube video from AiG about radiometric dating, and why it is supposedly unreliable for determining the age of rocks. Now, I am not a scientist, and most scientific discussion makes my eyes glaze over. My brain is wired for literature, poetry, and Biblical Studies. As I watched this short video, though, a few thoughts popped into my head that I just have to share.
First, take minutes and watch for yourself.
Many get fed up with Ken Ham and Answers in Genesis continually misrepresented normal science. Poor Ken, he has a thing about “billions of.
Most people envision radiometric dating by analogy to sand grains in an hourglass: the grains fall at a known rate, so that the ratio of grains between top and bottom is always proportional to the time elapsed. In principle, the potassium-argon K-Ar decay system is no different. Of the naturally occurring isotopes of potassium, 40K is radioactive and decays into 40Ar at a precisely known rate, so that the ratio of 40K to 40Ar in minerals is always proportional to the time elapsed since the mineral formed [ Note: 40K is a potassium atom with an atomic mass of 40 units; 40Ar is an argon atom with an atomic mass of 40 units].
In theory, therefore, we can estimate the age of the mineral simply by measuring the relative abundances of each isotope. Over the past 60 years, potassium-argon dating has been extremely successful, particularly in dating the ocean floor and volcanic eruptions. K-Ar ages increase away from spreading ridges, just as we might expect, and recent volcanic eruptions yield very young dates, while older volcanic rocks yield very old dates. Though we know that K-Ar dating works and is generally quite accurate, however, the method does have several limitations.
First of all, the dating technique assumes that upon cooling, potassium-bearing minerals contain a very tiny amount of argon an amount equal to that in the atmosphere. While this assumption holds true in the vast majority of cases, excess argon can occasionally be trapped in the mineral when it crystallizes, causing the K-Ar model age to be a few hundred thousand to a few million years older than the actual cooling age.
Secondly , K-Ar dating assumes that very little or no argon or potassium was lost from the mineral since it formed. But given that argon is a noble gas i. Finally —and perhaps most importantly—the K-Ar dating method assumes that we can accurately measure the ratio between 40K and 40Ar. I emphasize this assumption, because it is so commonly overlooked by those unfamiliar with radiometric dating!
We often take it for granted that measuring chemical concentrations should be an easy task, when it is not.
How accurate are Carbon-14 and other radioactive dating methods?

Others had tried. to find the answer in geological processes. many of the major institutions of young-Earth creationism such as Answers in Genesis and Carbon, like the potassium-argon and rubidium-strontium isotope dating methods.
The chronological figures related to genealogies in Scripture add up to approximately 6, years since the creation of described in Genesis. Many creationists consider these figures to be relatively complete, and thus the Earth is considered to be about 6, to perhaps as much as 10, years old. Biblical scholars do not agree on whether the Bible indicates that the planet Earth was created at the beginning of creation week or if it was already present as a lifeless, wet and dark planet here prior to creation week.
The Bible does not give an age for the Earth, nor is any theological point drawn from the age of the Earth, so it may not be as important as some of the other issues. Most scientists believe the Earth is about 4. This figure is based on radiometric dating. Some creationists have attempted to reconcile this figure with the creation in Genesis by proposing that the rocky, lifeless planet was created long ago perhaps 4.
Other creationists hold that the planet itself was created during creation week, perhaps early in the first day of creation.

Equipping youth pastors, parents, and students with Biblical answers for evolutionary teaching in public schools. Carbon dating assigns ages to once-living materials such as wood, bone, teeth, and shells. Evolutionary researchers do not use it to age-date rocks. It begins by measuring the ratio of radioactive versus stable versions of an element. Carbon dating works by basing an age calculation on the ratio of radioactive carbon 14 C to normal carbon 12 C in the atmosphere before nuclear bomb testing to the same ratio in the sample.
Carbon decays to nitrogen. Given the relatively short 14 C half-life of 5, years, organic materials purportedly older than , years nearly 18 half-lives should contain absolutely no detectable 14 C. However, coal, diamonds, and even dinosaur bones contain amounts of 14 C at levels detectable by modern instruments. Carbon dating begins with sound, repeatable science when researchers record isotope ratios.

The following comprises a series of essays written in response to a discussion held on the Message Board of this web site. The discussion, between a young creationist, Rob, and several other regular contributors, eventually came to the issue of radio isotope dating. Rob mentioned that Steve Austin’s Grand Canyon dating experiment cast doubt on the viability of absolute dating systems.
Naturally the notion was rebuffed and respondents pointed to articles heavily critical of the YEC experiment. Wanting to hear both sides of the issue, Rob wrote to Answers in Genesis, highlighting some particular lines written by Chris Stassen in an article critical of Austin’s Canyon work. The relevant lines were:.
Radiometric dating is based on the fact that radioactive isotopes decay to form isotopes of different elements. The starting isotope is called the.

Others had tried. But Drs Humphreys and Baumgardner realized that there were too many independent lines of evidence the variety of elements used in ‘standard’ radioisotope dating, mature uranium radiohalos, fission track dating and more that indicated that huge amounts of radioactive decay had actually taken place. It would be hard to imagine that geologic processes could explain all these.
Rather, there was likely to be a single, unifying answer that concerned the nuclear decay processes themselves.
Radiometric dating involves dating rocks or other objects by measuring the extent to which different radioactive No Answers in Genesis.
Radiocarbon dating can easily establish that humans have been on the earth for over twenty thousand years, at least twice as long as creationists are willing to allow. Therefore it should come as no surprise that creationists at the Institute for Creation Research ICR have been trying desperately to discredit this method for years. They have their work cut out for them, however, because radiocarbon C dating is one of the most reliable of all the radiometric dating methods.
This article will answer several of the most common creationist attacks on carbon dating, using the question-answer format that has proved so useful to lecturers and debaters. Answer: Cosmic rays in the upper atmosphere are constantly converting the isotope nitrogen N into carbon C or radiocarbon. Living organisms are constantly incorporating this C into their bodies along with other carbon isotopes.
When the organisms die, they stop incorporating new C, and the old C starts to decay back into N by emitting beta particles. The older an organism’s remains are, the less beta radiation it emits because its C is steadily dwindling at a predictable rate. So, if we measure the rate of beta decay in an organic sample, we can calculate how old the sample is. C decays with a half-life of 5, years. Question: Kieth and Anderson radiocarbon-dated the shell of a living freshwater mussel and obtained an age of over two thousand years.
ICR creationists claim that this discredits C dating. How do you reply?
