You’ve got two decay products, lead and helium, and they’re giving two different ages for the zircon. For this reason, ICR research has long focused on the science behind these dating techniques. These observations give us confidence that radiometric dating is not trustworthy. Research has even identified precisely where radioisotope dating went wrong. See the articles below for more information on the pitfalls of these dating methods. Radioactive isotopes are commonly portrayed as providing rock-solid evidence that the earth is billions of years old. Since such isotopes are thought to decay at consistent rates over time, the assumption is that simple measurements can lead to reliable ages. But new discoveries of rate fluctuations continue to challenge the reliability of radioisotope decay rates in general—and thus, the reliability of vast ages seemingly derived from radioisotope dating.
See this page in: Hungarian , Russian , Spanish. P eople who ask about carbon 14 C dating usually want to know about the radiometric  dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years. People wonder how millions of years could be squeezed into the biblical account of history.
How does the method attempt to estimate age? Can Science Measure Age? People often have grave misconceptions about radiometric dating.

Teaching about Radiometric Dating Students, particularly Young-Earth Creationists, may come in with misconceptions about how the age of the Earth and of various parts of the fossil record were determined.
For example, they may assume that the whole geologic timeline is based on radiocarbon dating, which only gives reliable results for dates back to 40, years before present Low, personal communication. Others will argue that decay rates could have changed Wise, , or that God could have changed them, which might result in too-old dates. The former argument is flawed because many radiometric dates are broadly supported by other estimates of change, such as tree rings and varved sediments for radiocarbon with some discrepancies, but still leaving the Earth far more than 6, years old.
The second is not a scientific argument. If supernatural forces are changing the laws of physics while we’re not looking, no form of science, “creation science” or otherwise, can prove or disprove it.
Creationist’s Blind Dates. The standard scientific estimate is that the universe is about 15 billion years old, the earth about 4. It is important to recognize from the start that there are independent procedures for obtaining each of these estimates, and that the procedures yield ranges of values that overlap. In the case of the universe, estimates can be obtained from astronomical methods or considerations of nuclear reactions.
Astrophysicists can measure the rate at which galaxies are receding and use these measurements to compute the time needed for the universe to expand to its present size.
Young Earth creationists tell us that we can’t. After all, it makes the same range of assumptions as other radiometric dating methods, and then.
Jul 7. Posted by Paul Braterman. Can we trust radiocarbon dating? After all, it makes the same range of assumptions as other radiometric dating methods, and then some. Other methods benefit from internal checks or duplications, which in the case of radiocarbon dating are generally absent. There are numerous cases where it appears to give absurdly old ages for young material, while apparent ages of a few tens of thousands of years are regularly reported for material known on other evidence to be millions of years old.
So can the Young Earth creationist 1 objections be rebutted, and if so how? The principle of radiometric dating is simple. For example, after one half-life we will have half the initial amount of that substance, after two half-lives only a quarter, after three half-lives just an eighth and so on, and there is a simple equation to deal with all amounts in between.

Cosmic-ray exposure dating. This dating method does on measuring certain nova produced by cosmic ray assumptions on exposed rock surfaces. Because cosmic rays constantly bombard meteorites flying through space, this crash has long been used to date the ‘ flight time’ of meteorites–that is the crash from when they were chipped off a larger body like an asteroid to the time they land on Earth. The cosmic rays produce small amounts of naturally-rare isotopes such as neon and helium-3, which can be measured in the laboratory.
The cosmic-crash exposure ages of meteorites are usually around 10 million years, but can be up to a billion years for some iron meteorites. In the last fifteen years, people have also used cosmic ray crash ages to genesis rock surfaces on the Earth.
Carbon dating does have a limit of about years. It is fairly accurate within that, but since human civilisation is not really that old, C14 dating methods work.
When some Christians first consider the possibility that Earth might have a much longer history than a few thousand years, they face a daunting challenge. Conventional scientists claim that dating methods are robust and reliable, but young-earth advocates insist that all are based on untestable assumptions and circular reasoning. Without the tools or expertise to independently evaluate the competing claims, many Christians default to the young-earth view, assuming there must be scientific justification for the young-earth claims.
For those of us who actually use these dating techniques, it is equally challenging to find ways to communicate the reliability of these methods in an understandable way. Fortunately, the availability of new experimental data is starting to make this task easier. We offer an example here of how independent dating methods can be combined to test assumptions and verify conclusions. Much more detail on this can be found in our recently published article in Perspectives on Science and Christian Faith.
The thin darker lines grow during winter or dry seasons, and the thicker, lighter rings during the summer or rainy seasons. So each pair typically represents one year.
A YOUNG EARTH? – A SURVEY OF DATING METHODS
The topic of radiometric dating and other dating methods has received some of the most vicious attacks by young earth creation science theorists. However, none of the criticisms of young earth creationists have any scientific merit. Radiometric dating remains a reliable scientific method.
What does carbon dating really show? •. What about other radiometric dating methods? •. Is there evidence that the Earth is young? •. PEOPLE who ask about.
Most people accept the current old-earth OE age estimate of around 4. This age is obtained from radiometric dating and is assumed by evolutionists to provide a sufficiently long time-frame for Darwinian evolution. And OE Christians theistic evolutionists see no problem with this dating whilst still accepting biblical creation, see Radiometric Dating – A Christian Perspective.
This is the crucial point: it is claimed by some that an old earth supports evolutionary theory and by implication removes the need for biblical creation. Some claim Genesis in particular, and the Bible in general looks mythical from this standpoint. A full discussion of the topic must therefore include the current scientific challenge to the OE concept.
This challenge is mainly headed by Creationism which teaches a young-earth YE theory.
Pictures Of Radiometric Dating – Dating methods and the age of the Earth
O ne of the main objections to radiometric dating on the part of young earth creationists is that radiometric ages do not agree with each other or that contamination renders ages meaningless. In fact, the claim is partially true. Early mass spectrometers were not as sensitive as machines today and the methods for separating, cleaning and analysis were less sophisticated.
Although ye-creationists like Snelling talk about contamination of isotopic systems as if it were a foreign concept to modern geology, most geochronologists routinely check for possible contamination using a variety of methods.
September 9, Radiometric dating methods have long been a target of young-earth creationists, and for good reason. Scientific Evidence for an Old Earth.
The rock walls were slippery and steep at points, and some people came in their dress shoes straight from the conference that brought them together. Let me see that. A brightly painted sign in the state park explained that million years ago these ancient creatures lived at the bottom of a warm, shallow sea during the Ordovician period. But none of these geologists believed it.
As young-earth creationists, they think the earth is about 8, years old, give or take a few thousand years. Creationist ideas about geology tend to appeal to overly zealous amateurs, but this was a gathering of elites, with an impressive wall of diplomas among them Harvard, U. They had spent years studying the geologic timetable, but they remained nevertheless deeply committed to a different version of history.
John Whitmore, a geologist from nearby Cedarville University who organized the field trip, stood in the middle of the fossil bed and summarized it for his son. Whitmore, who was wearing a suede cowboy hat, answered in a cowboy manner — laconic but certain. What was remarkable about the afternoon was not so much the fossils the bed is well picked over but the gathering itself, part of the First Conference on Creation Geology, held on the Cedarville campus.
Creationist geologists are now numerous enough to fill a large meeting room and well educated enough to know that in rejecting the geologic timeline they are also essentially taking on the central tenets of the field. But the participants in the conference insist that their approach is scientifically valid. Creationist geologists are thriving, paradoxically, at a moment when evangelicals are becoming more educated, more prosperous and more open to scientific progress.
How accurate are Carbon-14 and other radioactive dating methods?
Radioactive dating is a method of dating rocks and minerals using radioactive isotopes. This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks. Over naturally-occurring isotopes are known. Some do not change with time and form stable isotopes i.
Is the earth billions of years old or just thousands? Are radiometric methods of dating rocks and fossils reliable? What evidences support a young age for the.
Radiometric dating , radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon , in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay. Together with stratigraphic principles , radiometric dating methods are used in geochronology to establish the geologic time scale.
By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change. Radiometric dating is also used to date archaeological materials, including ancient artifacts. Different methods of radiometric dating vary in the timescale over which they are accurate and the materials to which they can be applied.
All ordinary matter is made up of combinations of chemical elements , each with its own atomic number , indicating the number of protons in the atomic nucleus. Additionally, elements may exist in different isotopes , with each isotope of an element differing in the number of neutrons in the nucleus. A particular isotope of a particular element is called a nuclide. Some nuclides are inherently unstable.
How Good Are Those Young-Earth Arguments?
David H. Bailey does not work for, consult, own shares in or receive funding from any company or organisation that would benefit from this article, and has disclosed no relevant affiliations beyond their academic appointment. In one respect, science and religion have been largely reconciled since the 19th century, when geologists such as Charles Lyell recognised the evidence for a very old Earth.
Within a few decades, most mainstream religious denominations accepted this view as well.
other young-Earth creationists have never found any rock on Earth that gives an age date of 6, years no matter what age dating method is.
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.
