Isochron Dating

See this page in: Hungarian , Russian , Spanish People who ask about carbon 14C dating usually want to know about the radiometric [1] 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. Clearly, such huge time periods cannot be fitted into the Bible without compromising what the Bible says about the goodness of God and the origin of sin, death and suffering —the reason Jesus came into the world See Six Days? Christians , by definition, take the statements of Jesus Christ seriously. This only makes sense with a time-line beginning with the creation week thousands of years ago. It makes no sense at all if man appeared at the end of billions of years. We will deal with carbon dating first and then with the other dating methods.

The Truth About Dating Methods

The belief that radiodating methods give absolute measurements of time is widespread as a result of scientific popularization in journals, conferences, and the media. In fact, due to the difficulties in applying the experimental method to events in the past, all chronometers based on natural or artificial nuclear disintegration need a calibration.

This calibration supposes a great number of basic assumptions concerning initial conditions. The choice of these initial conditions affects the results.

The relative dating methods themselves are generally sound when used with good assumptions. However, when scientists apply relative dating to a preconceived uniformitarianism model, the dating methods are only as good as the model. This article is also available in Spanish.

Robert Holloway home In the continuing disagreement between religious fundamentalists and mainstream science, the subject of various dating methods is often discussed. Typically, fundamentalists are upset by the implications of the scientific dating methods since these methods often show an earth must older than the fundamentalists are willing to accept.

Even the radiocarbon method often comes in for criticism although it is suitable only for objects less than 50, years old. This criticism usually comes from Young Earth Creationists who believe that the earth is less than 10, years old. Because the radiocarbon method can reliably date carbon containing objects much older than this, they apparently feel uncomfortable with the results. One such critique regarding the carbon method was published by Apologetics Press of Montgomery, Alabama.

Age Dating the Earth

Radiocarbon Dating and the Bible Is carbon dating or radiocarbon dating always reliable and beyond question? Are all radioactive dating methods unreliable? Have carbon C14 dates millions of years old been proven wrong? Is carbon dating useless before 2, B. Or are the above statements all false, and the truth is something else?

on Radioactive and Other Dating Methods. Essays on Origins. Dr. David Menton, The problem with all radiometric “clocks” is that their accuracy critically depends on several starting assumptions which are largely unknowable.” Creationists Call Their Shot.

How accurate are carbon-dating methods? All methods of radioactive dating rely on three assumptions that may not necessarily be true: Rate of Decay It is assumed that the rate of decay has remained constant over time. This assumption is backed by numerous scientific studies and is relatively sound. However, conditions may have been different in the past and could have influenced the rate of decay or formation of radioactive elements. Evolutionists assume that the rate of cosmic bombardment of the atmosphere has always remained constant and that the rate of decay has remained constant.

Thus radioactive dating relies purely on assumptions. We could put forward the following counter arguments to the constancy of these assumptions:

SCIENCE vs. EVOLUTION

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.

How does carbon dating work? 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.

Jan 11,  · SEVEN INITIAL ASSUMPTIONS At the very beginning of this analysis, we need to clearly understand a basic fact: Each of these special dating methods can only have accuracy IF (if!) certain assumptions ALWAYS (always!) apply to EACH specimen that is tested.

There are lots of ways to guesstimate ages, and geologists knew the earth was old a long time ago and I might add that they were mostly Christian creationist geologists. But they didn’t know how old. Radiometric dating actually allows the measurement of absolute ages, and so it is deadly to the argument that the earth cannot be more than 10, years old.

Radiometric methods measure the time elapsed since the particular radiometric clock was reset. Radiocarbon dating, which is probably best known in the general public, works only on things that were once alive and are now dead. It measures the time elapsed since death, but is limited in scale to no more than about 50, years ago. Generally applied to igneous rocks those of volcanic origin , they measure the time since the molten rock solidified.

If that happens to be longer than 10, years, then the idea of a young-Earth is called into question. If that happens to be billions of years, then the young-Earth is in big trouble. As of January, , The oldest rocks found on earth are 4. This is reported in the paper Priscoan 4. Williams; Contributions to Mineralogy and Petrology 1:

Radiocarbon dating

Until recent years, scientists who believe in creation haven’t had the necessary resources to explore radiometric dating in detail. A 10 gram sample of U Now that has changed, and some important discoveries are being made. When granite rock hardens, it freezes radioactive elements in place.

Also, different radiometric dating techniques independently converges with each other and with other dating techniques such as dendrochronology, layers in sediment, growth rings on corals, rhythmic layering of ice in glaciers, magnetostratigraphy, fission tracks and many other methods.

Shop Now Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth. Many people have been led to believe that radiometric dating methods have proved the earth to be billions of years old. With our focus on one particular form of radiometric dating—carbon dating—we will see that carbon dating strongly supports a young earth. Note that, contrary to a popular misconception, carbon dating is not used to date rocks at millions of years old.

Basics Before we get into the details of how radiometric dating methods are used, we need to review some preliminary concepts from chemistry. Recall that atoms are the basic building blocks of matter. Atoms are made up of much smaller particles called protons, neutrons, and electrons. Protons and neutrons make up the center nucleus of the atom, and electrons form shells around the nucleus.

The number of protons in the nucleus of an atom determines the element. For example, all carbon atoms have 6 protons, all atoms of nitrogen have 7 protons, and all oxygen atoms have 8 protons. The number of neutrons in the nucleus can vary in any given type of atom. So, a carbon atom might have six neutrons, or seven, or possibly eight—but it would always have six protons.

The illustration below shows the three isotopes of carbon. There are two main applications for radiometric dating.

Evolution’s Radiometric Dating Methods: Are they accurate?

Are There Gaps in the Genesis Genealogies? Many view the original New Answers Book as an essential tool for modern discipleship. Both of these books answer such questions as: Can natural processes explain the origin of life? Can creationists be real scientists?

Jan 04,  · Secondly, radiometric dating methods (K-Ar in particular) do not estimate the age of a rock, The assumptions that go into the dating and the layers of assumptions into the earth dating (at the time) were never taught, and I was being trained to teach high school students. Has Answers in Genesis debunked K-Ar dating? (

Though they may know it as carbon dating or carbon 14 dating, there is an understood notion that when anything old is found, like an ancient artifact, it can be radiocarbon dated to find out exactly how old it is. Yet, as simple and straightforward as this seems, the process of dating objects via radiocarbon is far from simple and straightforward. Here I will present what radiocarbon is, the dating methods, the assumptions that govern them, and the known discrepancies that plague the method.

With a thorough understanding of this dating method, it is my opinion that its ingenious fundamentals can be appreciated, yet greatly overshadowed by its limitations. Radiocarbon Every day cosmic rays bombard our atmosphere. These cosmic rays release free neutrons which zip around our nitrogen rich atmosphere at high velocities.

As the Carbon 14 slowly descends into our lower atmosphere it bonds with oxygen becoming the very unpopular CO2 greenhouse gas Bowman, Though the vast majority of CO2 is comprised of the more common and stable isotope of carbon, carbon 12 C12 , a small fraction of CO2 one in million , contains C

Answers to Creationist Attacks on Carbon-14 Dating

Katherine Loop On a recent trip to the Grand Canyon, I was reminded of how misunderstood dating methods have become. Few understand that the answer to a math problem is only as accurate as the starting information—and that in the case of dating methods, that starting information is based on unverifiable assumptions. The area of a rectangle equals the length times the width. Now, that area is correct if and only if the length is 5 feet and the area is 4 feet.

There are several methods of radiometric dating. Carbon dating has limited value for evolution because its half-life is too short. The method assumes that the production of Carbon in the atmosphere from nitrogen is a process that is in equilibrium, and it is not. The other methods deal with dating igneous rocks.

See this page in: Russian How old is planet Earth? There are enormous differences of opinion. The most common view is that Earth is approximately 4. The lowest age defended on a scientific basis is in the 6 to 10 thousand year range. Theoretically, Creationism remains workable within a wide range of age estimates. Scientists have proposed numerous age estimation methods. Most systems promoted by Evolutionists involve radioactivity. Various radioactive elements are involved, including Carbon , Uranium , Thorium , and Potassium And it does not work on rocks or thoroughly mineralized fossils; it is only useful for relatively well-preserved organic materials such as cloth, wood, and other non-fossilized materials.
